Why Packaging Machinery Spans the Entire Gearbox Precision Spectrum — From Food-Grade P0 to Economy P2

EP-FAL planetary gearbox installed in form-fill-seal packaging machine jaw drive — IP65 washdown 600 cycles/min high-speed servo

Korea Ever-Power EP-FAL integrated belt-pulley planetary gearbox — FFS jaw drive and high-speed conveyor applications. IP65 on every unit; rated for 600 cycles/min at daily washdown environments.

No other industry places as wide a range of gearbox requirements within a single production line as packaging. A form-fill-seal machine may have a jaw drive running at 600 cycles per minute with IP65 washdown and ≤3 arc-min backlash, a film draw roller running at 6,000 rpm input needing low heat generation, a rotary indexing station demanding ±0.01° positional accuracy, and a carton folding axis where ≤8 arc-min economy-grade precision is perfectly sufficient at 18% lower cost. All on the same machine, all driven by servo motors, all connecting through a planetary gearbox.

This range — from food-grade EP-FADS P0 on a liquid filling nozzle axis to EP-FPG P2 on a carton erector — is exactly what Korea Ever-Power’s eight-series architecture is designed for. The C1–C10 universal motor adapter system means a packaging machine OEM that qualifies a single Yaskawa servo motor model covers every gearbox on the BOM, from the precision filling axis to the economy-tier infeed belt drive. One qualification. One adapter catalogue item. Zero re-engineering when the series changes between drive points on the same machine.

The IP65 requirement is the second defining characteristic of packaging applications. Daily CIP (clean-in-place) washdown cycles with hot water, caustic cleaning agents, and pressurised spray are the operating environment for food and pharmaceutical packaging lines — not an exceptional event. A gearbox with a failed IP seal allows cleaning agents into the lubrication chamber. Korea Ever-Power applies pneumatic pressure decay testing to every EP-FAL, EP-FAB, EP-FAD, and EP-FADS unit before shipment — the same 60-second pressure test on the last unit of the day as on the first. This is not an inspection sampling standard: it is a 100% production test.

The FFS Jaw Drive: 600 Cycles/Min, IP65, and the Eccentricity Problem

A form-fill-seal cross-seal jaw drive cycles from open to closed and back 600 times per minute at the maximum rated throughput of a high-speed pouch machine. The jaw drive gearbox must survive daily washdown, maintain IP65 seal integrity under repeated thermal cycling, and deliver backlash ≤3 arc-min to keep jaw registration within the heat-seal tolerance. EP-FAL solves the additional problem of belt hub eccentricity: in conventional FFS jaw drives with a separate belt pulley hub bolted to the gearbox output shaft, hub-to-shaft eccentricity of 0.05–0.12 mm generates a periodic jaw registration error at belt rotation frequency. EP-FAL’s integrated pulley eliminates this interface — pulley bore and gearbox output shaft are the same machined surface, zero eccentricity.

Application Scenarios

Six Packaging Machine Applications — Series, Engineering Rationale, and Critical Specifications

The six scenarios below cover the drive types that packaging machine engineers encounter most frequently when specifying planetary gearboxes. They range from the most demanding (high-speed FFS jaw drive with daily CIP washdown) to the most cost-sensitive (economy-tier carton folding and case packing), representing the full width of the packaging machinery gearbox market.

01 — Form-Fill-Seal Cross-Seal Jaw Drive

High-speed pouch / sachet / pillow pack machine

EP-FAL P1
Frame 090–150 mm
600 cycles/min

The FFS jaw drive runs at the highest acceleration-deceleration duty of any packaging machine axis — reciprocating from full open to closed and back 600 times per minute, with the jaw force profile generating peak torque at reversal points. The conventional solution uses a gearbox plus a separate belt pulley hub; the hub-to-shaft eccentricity (typically 0.08 mm) generates a periodic jaw registration error at belt rotation frequency that adds to the total heat-seal positioning uncertainty. EP-FAL’s integrated timing belt pulley eliminates this interface: pulley bore and output shaft are the same machined surface, reducing periodic registration error from 0.08 mm to ≤0.015 mm in the same machine design — the difference between a customer acceptance and a rejection on tight seal tolerance specifications.

Key spec: F_rad 34,200 N (AT10 jaw belt); IP65 every unit; 5–20:1 ratio; 5,000 rpm max input; 30,000 hr S5 design life; NYOGEL 792D for daily CIP washdown with no relubrication interval.

02 — High-Speed Rotary Indexing Drive

Precision station indexer — carousels, turntables, dial plates

EP-FAB P0
Frame 090–110 mm
≤1 arc-min P0

Rotary indexing drives in high-speed packaging machines — dial-plate stations, carousel bottle conveyors, rotary filling heads — require ±0.01° angular repeatability to maintain station-to-station registration. At a carousel radius of 200 mm, 1 arc-min of uncompensated backlash produces 0.058 mm of linear position error — sufficient to cause bottle misalignment on a 4-lane filling head or label placement offset on a rotary labeller. EP-FAB P0, with individual backlash grade stamped on every unit at ≤1 arc-min, is the standard specification for these drives. The high fatigue life of the DIN Class 5 profile-ground gears sustains ±0.01° accuracy over 30-million-cycle production runs between maintenance intervals.

Key spec: ≤1 arc-min P0 individual stamp; 5–20:1 ratio; 4,000 rpm max input; IP65; 20,000 hr S5 life; DIN Class 5 profile-ground ring gear — same standard as European premium brands.

03 — Liquid Filling Machine Nozzle Axis

Food-grade precision fill volume control

EP-FADS P0
Frame 047–060 mm
Food-grade NYOGEL

Liquid filling machine nozzle axes require P0 precision for repeatable fill volume: the nozzle valve position at the moment of cut-off determines fill weight deviation, and backlash in the valve actuator drive directly adds to fill weight variation. Food and pharmaceutical regulations require that lubricant is contained — no external grease points, no relubrication intervals, and no lubricant egress onto the product contact surface. EP-FADS P0 with NYOGEL 792D sealed lifetime fill satisfies all three requirements: the motor shaft inserts directly into the gearbox (no external adapter plate that could trap contamination), NYOGEL 792D is contained within the sealed housing, and the compact 047–060 mm frame fits within the tight envelope of a rotary filling head.

Key spec: NYOGEL 792D sealed lifetime fill — no external grease points; ≤1 arc-min P0; direct-insert motor (no adapter plate contamination trap); IP65; 6,000 rpm max input; 30,000 hr design life.

04 — Thermoformer Forming Station Drive

Sheet forming indexer — cold-chain packaging lines

EP-FAB P1
Frame 090–110 mm
−10°C to +90°C

Thermoformers for cold-chain and chilled food packaging operate in environments where forming station temperatures cycle between ambient and chilled film temperatures, and the machine may be in a refrigerated production hall at below 0°C ambient. The gearbox must maintain seal integrity and lubrication performance across this temperature range. EP-FAB P1 with NYOGEL 792D is rated for continuous operation down to −10°C — the lowest rated temperature among the EP-series for cold-chain packaging environments. IP65 is standard: forming station wash cycles use high-pressure hot water that would rapidly ingress a batch-sample-tested IP seal.

Key spec: NYOGEL 792D rated −10°C minimum; IP65 every unit; ≤3 arc-min P1; 10–30:1 ratio; 4,000 rpm input; 20,000 hr S5 life for forming station high-cycle duty.

05 — Labelling Machine Carousel / Turret Drive

Container rotation — wet-glue, self-adhesive, sleeve labellers

EP-FAD P1
Frame 060–090 mm
≤56 dB noise

Labelling machine carousels and turret drives operate at 100–400 container rotations per minute with smooth, vibration-free motion — vibration in the container drive produces label placement error and wrinkle in self-adhesive sleeves. EP-FAD P1 with helical planet gears delivers the lowest vibration level in this frame size range among Korea Ever-Power’s standard production: helical meshing geometry generates approximately 60% lower vibration amplitude than straight-cut gear designs at equivalent pitch-line velocity. Low noise (≤56 dB at FAD060) satisfies production hall noise requirements without acoustic enclosures around the labelling head.

Key spec: ≤56 dB at rated speed; ≤3 arc-min P1; 5–16:1 ratio; 6,000 rpm max input; IP65 washdown; 30,000 hr design life; NYOGEL 792D compatible with food/pharma cleanroom-adjacent environments.

06 — Carton Erector / Case Packer Economy Drives

Folding cams, infeed belts — secondary packaging OEM

EP-FPG P2 / FPGA
Frame 040–090 mm
≤5–8 arc-min

Carton erectors, carton folders, and case packer infeed belts operate in secondary packaging environments where ≤8 arc-min (economy-grade) backlash is fully adequate for the motion requirements, and where production volumes of 50–500 units per machine BOM make unit cost a significant factor. EP-FPG P2 (≤5 arc-min) and EP-FPGA standard grade (≤8 arc-min) deliver closed-loop position control accuracy at 35–50% lower cost than EP-FAB at the same frame size. The FPGA square housing mounts flat against carton erector frame faces without an adapter bracket — the same simplification that makes it effective in conveyor automation.

Key spec: Economy tier pricing; IP65 option (carton erectors with wash duties); 10–50:1 ratio; 3,000 rpm input; 20,000 hr S5 life; C1–C10 universal adapter for same motor as precision axes on the same line.

Every Unit

The EP-FAL integrated pulley is machined from the same forging as the output shaft — not a separately machined hub pressed or keyed onto the shaft. There is no tolerance accumulation between the gear centreline and the belt pitch circle.

Four EP-FAL Design Features That Matter for Packaging

Packaging machine builders have used conventional gearbox-plus-pulley-hub arrangements for decades because the alternative — a purpose-built integrated pulley gearbox — has not been available in a standard production item at competitive pricing. EP-FAL changes that equation. Four internal design features explain why:

01
Integrated Timing Belt Pulley — Zero Hub-Shaft Eccentricity

In a standard gearbox-plus-hub arrangement, the belt pulley is a separate component clamped or keyed onto the output shaft. The manufacturing tolerance between the hub bore and the shaft OD (typically h6/H7 fit) produces a concentricity error of 0.03–0.05 mm. The keyway adds a further angular offset. Total hub-to-shaft TIR of 0.05–0.12 mm appears as a periodic positional error at belt rotation frequency — in a 600 cycles/min FFS jaw drive, this is a 600 Hz error signal that the servo controller cannot fully compensate. EP-FAL’s integrated pulley machined from the same component as the output shaft has zero additional concentricity — the gear output axis and the belt pitch circle share the same centreline by design, not by tolerance. Documented result: periodic jaw registration error reduced from 0.08 mm to ≤0.015 mm in direct machine substitution tests.
02
Oversized Output Bearing for Belt Radial Load — F_rad to 34,200 N

A standard planetary gearbox output bearing is sized for torque transmission, not for sustained radial belt loads. When a separate pulley is added to a standard gearbox output shaft, the belt tension force creates a bending moment at the output bearing that exceeds its design load — reducing bearing life by a factor of 2–5× depending on belt tension and shaft overhang length. EP-FAL specifies an oversized output bearing as part of the standard design, rated for maximum radial force of 34,200 N at the frame sizes relevant to FFS jaw drives. No external support bearing is needed.
03
NYOGEL 792D Sealed Lifetime Fill — No Washdown Relubrication

NYOGEL 792D synthetic grease is rated for −10°C to +90°C continuous operation and is contained within the sealed housing — no external lubrication points, no grease nipples. In a packaging machine subjected to daily CIP washdown cycles, the absence of lubrication maintenance points eliminates two risks: the risk of washdown water entering the gearbox through a grease fitting, and the risk of lubricant egress onto the product contact area during a relubrication event. The sealed lifetime design covers the full 30,000-hour S5 design life without any scheduled lubrication service.
04
IP65 Pneumatic Pressure Decay — Every Unit, Not Batch Sample

Every EP-FAL unit undergoes a 60-second pneumatic pressure decay test at all dynamic seal interfaces before shipment. This test identifies any IP seal that would fail under the first production washdown cycle — a failure mode that batch-sample testing cannot reliably detect across a production lot. For packaging machine builders supplying to food and pharmaceutical customers, the difference between “IP65 tested” and “IP65 every unit tested” is the difference between a supplier qualification that passes the customer’s incoming inspection criteria and one that requires a corrective action report after the first field failure.

The combined effect of these four features — zero eccentricity, oversized bearing, sealed NYOGEL fill, and 100% IP65 testing — is that the EP-FAL replaces not just the gearbox in a jaw drive design, but the entire gearbox-plus-hub-plus-external-support-bearing sub-assembly, reducing the drive assembly parts count from four components to one.

Korea Ever-Power — IP65 on Every Unit, Grade-Stamped Backlash, and Food-Grade Lubrication

Korea Ever-Power test center — IP65 pneumatic pressure decay testing and backlash measurement for EP-FAL packaging machine gearboxes

IP65 pressure test station (every unit, 60-second decay test) and gear-grinding workshop at Korea Ever-Power, Ansan-si, Korea.

Three production quality standards differentiate Korea Ever-Power EP-FAL and EP-FAB from alternative packaging gearbox suppliers — and all three are directly relevant to the operating environment of food, beverage, and pharmaceutical packaging lines.

IP65 on every unit: Packaging machine OEMs and end-users have reported IP seal failures in competitive gearboxes within 3–6 months of production washdown operations. The failure mode is predictable: a gearbox that passes a batch-sample IP test but has a marginal seal on the production unit that was not individually tested will allow cleaning agent ingress within the first thermal cycling of the seal material under washdown temperature. Korea Ever-Power’s 60-second pneumatic pressure decay test on every EP-FAL, EP-FAB, EP-FAD, and EP-FADS unit identifies marginal seals before they ship — not after they fail in the field.

Individual backlash grade stamping: Packaging machine acceptance tests typically include a jaw registration or station-to-station accuracy check. When a machine fails this test after installation, the engineer needs to know whether the gearbox’s actual backlash is within the specified grade. With batch-sample testing, the answer is “probably, based on the sample” — which does not satisfy a machine acceptance protocol. With Korea Ever-Power’s per-unit stamping, the answer is “yes, this specific unit measured X arc-min at 2% rated torque on this date” — a directly auditable datum.

NYOGEL 792D sealed lifetime fill: In food and pharmaceutical packaging environments, any lubricant that exits the gearbox is a potential product contamination event and a regulatory non-compliance. NYOGEL 792D in EP-FADS, EP-FAB, and EP-FAD is contained in a sealed housing with no external access points. There is no scheduled relubrication event that could result in accidental grease discharge onto a product contact surface.

✅

Three Tests on Every EP-FAL / EP-FAB Unit — Not Batch Sampling

(1) Backlash measurement: Loaded at 2% rated torque; measured grade stamped on nameplate. (2) IP65 pressure decay: 60-second pneumatic test on all dynamic seal interfaces; pass required before packing. (3) Noise and vibration: Closed-loop servo dynamometer test; units above noise threshold are regraded or rejected. These three tests apply to every unit, on every production shift, regardless of order size — 1 unit or 500 units receives the same testing standard.

What Packaging Machine Engineers Say About EP-FAL and EP-FAB

★★★★★

“We had a persistent jaw registration problem on our 600-cycle FFS machine — a periodic ±0.09 mm error at belt rotation frequency that our servo tuning could not fully compensate. Switched to EP-FAL with the integrated pulley. The periodic error dropped to ±0.015 mm on the first machine. We haven’t touched the servo parameters since. The customer’s seal integrity test went from 94% pass to 99.7%. EP-FAL solved a problem we’d been fighting with separate-hub designs for three years.”

Shin B., Lead Mechanical Engineer

Form-Fill-Seal Machine Manufacturer — Busan, Korea

★★★★★

“Our rotary filling machine uses EP-FADS P0 on the nozzle axes. The food-grade requirement was non-negotiable — the customer specified sealed lifetime lubrication, no external grease points, and IP65 on a 24/7 CIP washdown line. EP-FADS checked all three boxes. The direct-insert motor mounting also eliminated the adapter-plate contamination trap we’d had on a previous design — no crevices for product residue around the gearbox input end. The P0 grade stamp went directly into our CE documentation without any additional test data.”

Oh J., Principal Design Engineer

Liquid Filling Machine OEM — Incheon, Korea

★★★★★

“We build a 12-station indexing carousel for cosmetic packaging. Station repeatability spec is ±0.02 mm at 150 mm carousel radius — which requires ≤1 arc-min backlash after our servo compensation. EP-FAB P0 with the per-unit backlash stamp gave us documented traceability for each machine’s qualification record. After switching from a European brand, the unit cost saving was 32%. The C1–C10 adapter covered our Mitsubishi servo motors without any engineering change — same adapter we use on the economy FPG drives on the same machine’s infeed conveyor.”

Frequently Asked Questions — Packaging Machine Gearbox Selection

Why does the FFS jaw drive need an integrated belt pulley rather than a standard gearbox plus hub?＋

The jaw drive problem is not backlash — it is hub eccentricity. In a conventional gearbox-plus-hub setup, the belt pulley is a separate component that mounts onto the output shaft via a keyway or clamp. The manufacturing tolerance between the hub bore and the output shaft diameter (typically h6/H7 = 0–25 µm clearance, plus keyway angular offset) produces a concentricity error of 0.03–0.12 mm. This eccentricity appears at the jaw as a periodic position deviation at belt rotation frequency — in a 600-cycle-per-minute jaw drive running a 100 mm pitch-diameter pulley at 1,500 rpm, the error repeats 1,500 times per minute, which the servo controller processes as a disturbance it must compensate at every cycle. EP-FAL eliminates the hub-shaft interface entirely: the pulley groove is machined on the same forging as the output shaft, sharing the same centreline. Documented result from a direct substitution in a 600-cycle FFS machine: periodic registration error reduced from ±0.09 mm to ±0.015 mm. The servo parameters did not require re-tuning.

What does “IP65 on every unit” mean in practice for a packaging line?＋

IP65 certification means the gearbox is sealed against dust ingress and against water jets from any direction at up to 12.5 litres per minute. The critical word in Korea Ever-Power’s quality standard is “every unit” — not “batch sample” or “AQL sampling plan.” Every EP-FAL, EP-FAB, EP-FAD, and EP-FADS unit leaving the Ansan-si production facility has passed a 60-second pneumatic pressure decay test on all dynamic seal interfaces (input shaft seal, output shaft seal, housing joint seals). A unit that shows any pressure decay above the threshold is rejected and does not ship. In practical terms for a packaging OEM: the probability that a gearbox in your production line has a marginal IP seal that passes the batch-sample inspection standard but fails on the first CIP washdown cycle is eliminated by design — it cannot pass the production line test. This matters most for food and pharmaceutical lines where a gearbox IP failure is a potential contamination event rather than just a maintenance call.

Is NYOGEL 792D in EP-FADS suitable for direct food-contact applications?＋

NYOGEL 792D is a synthetic hydrocarbon grease contained within the sealed EP-FADS housing with no external access points. It is not an H1 food-grade lubricant under the NSF registration system — it is not formulated for incidental food contact. However, because it is sealed within the gearbox housing and there are no external grease nipples, grease ports, or relubrication events, the probability of lubricant contact with the product stream is by design near zero under normal operating conditions. For applications where the gearbox is located within a product contact zone and regulatory compliance requires H1 or H2 lubricant certification, consult Korea Ever-Power application engineering to confirm whether an H1-certified grease substitution is available for your specific frame size and operating temperature. Contact [email protected] with your application details and required certifications.

Can EP-FAL handle the full AT10 belt tension at 600 cycles per minute without external support?＋

Yes, within the rated frame sizes. EP-FAL specifies a maximum radial force of 34,200 N at the rated overhang distance for the relevant frame sizes (FAL110 through FAL280). This rating includes the dynamic belt tension component from the jaw acceleration-deceleration profile at 600 cycles per minute. An AT10 belt of standard width for a 090–150 mm frame jaw drive generates a peak belt tension well within this envelope at rated machine speed. The output bearing in EP-FAL is oversized relative to the standard EP-FAB output bearing — it is specified as part of the FAL design specifically to carry the sustained radial belt load without lifetime reduction. For non-standard belt configurations (extra-wide AT10, multi-strand AT5, or operating beyond the rated overhang distance), contact Korea Ever-Power application engineering with your belt specification, jaw mass, and cycle rate — a bearing life calculation can be provided as part of the application engineering review.

How does the C1–C10 motor adapter simplify a packaging machine BOM with multiple gearbox series?＋

A typical high-speed packaging machine may have four or five different gearbox series on the BOM — EP-FAL for the jaw drive, EP-FAB P0 for the rotary indexer, EP-FADS for the filling nozzle, EP-FAD for the film draw roller, and EP-FPG for the infeed conveyor. With a conventional gearbox supplier, each series would require a separate motor adapter qualification: different adapter ring geometries, different torque specifications, different installation procedures. With Korea Ever-Power C1–C10, the adapter ring geometry for a given servo motor model is identical across all eight series. The same C7 adapter (for example) that you qualify for your Yaskawa SGMJV-04A motor on the EP-FAL jaw drive installs unchanged on the EP-FADS filling axis and the EP-FPG conveyor drive. One qualification documentation package covers the entire motor-gearbox interface for the full BOM. When the machine specification changes and EP-FPG is upgraded to EP-FAB on a particular axis, the motor adapter does not change — only the gearbox body changes.

Specify EP-FAL, EP-FAB, or EP-FADS for Your Packaging Machine

Send your drive point list with motor model, cycle rate, and IP requirement — Korea Ever-Power will provide a full series and frame-size recommendation for every axis within 24 hours. One C-adapter qualification covers the complete BOM.
