Engineered for general-purpose servo and stepper motor applications, it delivers a balance of accuracy, compactness, and value that makes it the default starting point for machine builders worldwide.<\/p>\n<p>Four frame sizes \u2014 EP-PL\/PF60, EP-PL\/PF80, EP-PL\/PF120, and EP-PL\/PF160 \u2014 cover motor power from 50\u2009W compact steppers to 7,500\u2009W heavy-duty servo drives. One-stage, two-stage, and three-stage configurations provide 22 standard gear ratios from 3:1 through 512:1, all manufactured in our Ansan-si precision gear facility using 5-axis CNC hobbing and grinding processes.<\/p>\n<p>Both round flange (EP-PL) and square flange (EP-PF) output variants share identical internal gear trains, bearings, and seals \u2014 the only difference is the output housing geometry. This lets you standardise on one gearbox platform across machines that require different mounting interfaces.<\/p>\n<p><a style=\"display: inline-block; background: #005baa; color: #fff; font-weight: 600; font-size: clamp(13px,1.5vw,15px); padding: 12px 28px; border-radius: 6px; text-decoration: none; margin-top: 12px; transition: all .2s;\" href=\"https:\/\/planetary-gearboxes.cn\/ko\/contact-us\/\">Request a Quote \u2192<\/a><\/p>\n<\/div>\n<div style=\"flex: 1 1 300px; min-width: 260px;\"><!-- Product Image Placeholder --><br \/>\n<img decoding=\"async\" style=\"width: 100%; max-width: 480px; border-radius: 8px; display: block; margin: 0 auto;\" src=\"https:\/\/planetary-gearboxes.cn\/wp-content\/uploads\/2026\/06\/EP-PL_PF-Series-Standard-Precision-Planetary-Gearbox.webp\" alt=\"EP-PL\/PF Series Standard Precision Planetary Gearbox - round flange and square flange inline output\" title=\"\"><br \/>\n<!-- Key Stats Row --><\/p>\n<div style=\"display: flex; flex-wrap: wrap; gap: 10px; margin-top: 16px; justify-content: center;\">\n<div style=\"background: #f5f8fc; border: 1px solid #dce6f0; border-radius: 6px; padding: 10px 16px; text-align: center; flex: 1 1 90px;\">\n<div style=\"font-size: clamp(18px,2.2vw,24px); font-weight: 800; color: #005baa;\">\u22648\u2032<\/div>\n<div style=\"font-size: 11px; color: #6b7b8d; margin-top: 2px;\">Backlash (P1)<\/div>\n<\/div>\n<div style=\"background: #f5f8fc; border: 1px solid #dce6f0; border-radius: 6px; padding: 10px 16px; text-align: center; flex: 1 1 90px;\">\n<div style=\"font-size: clamp(18px,2.2vw,24px); font-weight: 800; color: #005baa;\">720<\/div>\n<div style=\"font-size: 11px; color: #6b7b8d; margin-top: 2px;\">N.m Max Torque<\/div>\n<\/div>\n<div style=\"background: #f5f8fc; border: 1px solid #dce6f0; border-radius: 6px; padding: 10px 16px; text-align: center; flex: 1 1 90px;\">\n<div style=\"font-size: clamp(18px,2.2vw,24px); font-weight: 800; color: #005baa;\">\u226596%<\/div>\n<div style=\"font-size: 11px; color: #6b7b8d; margin-top: 2px;\">Efficiency (1-stg)<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<h2 style=\"font-size: clamp(20px,2.8vw,28px); font-weight: bold; color: #0a1628; margin: 36px 0 8px; padding-bottom: 8px; border-bottom: 3px solid #005baa; display: inline-block;\">Available Frame Sizes \u2014 From Compact to Heavy-Duty<\/h2>\n<p>The EP-PL\/PF planetary gearbox range spans four frame sizes.

The only difference is the output flange geometry: EP-PL has a round bolt-circle flange suited for rotary applications, while EP-PF has a square corner-bolt flange preferred for linear-motion and rack-and-pinion installations.

Each frame covers a specific motor shaft range (Frame 60: 6\u201319 mm, Frame 80: 8\u201322 mm, Frame 120: 14\u201335 mm, Frame 160: 19\u201342 mm). Verify that your motor\u2019s shaft diameter falls within the frame\u2019s compatible range, then confirm the required output torque does not exceed the rated torque for your chosen ratio. Our engineers can confirm the selection within 24 hours if you send your motor model number to sales@planetary-gearboxes.cn.<\/div>\n<\/details>\n<details style=\"border: 1px solid #e8eef4; border-radius: 6px; margin-bottom: 10px; overflow: hidden;\" open=\"open\">\n<summary style=\"padding: 14px 18px; cursor: pointer; font-weight: 600; color: #0a1628; background: #f5f8fc; font-size: clamp(14px,1.5vw,16px); list-style: none;\">\u25b6 Can the EP-PL\/PF gearbox handle frequent reversing applications?<\/summary>\n<div style=\"padding: 14px 18px; font-size: 14px; line-height: 1.7; color: #444;\">Yes. For applications with frequent CW\/CCW reversals, specify the OP4 reinforcement integral hoop clamp coupling instead of the standard OP1. The OP4 coupling features a reinforced clamping structure specifically designed for the cyclic loading pattern of reversing duty. This is common in servo press drives, oscillating conveyors, and pick-and-place reciprocating axes.<\/div>\n<\/details>\n<details style=\"border: 1px solid #e8eef4; border-radius: 6px; margin-bottom: 10px; overflow: hidden;\" open=\"open\">\n<summary style=\"padding: 14px 18px; cursor: pointer; font-weight: 600; color: #0a1628; background: #f5f8fc; font-size: clamp(14px,1.5vw,16px); list-style: none;\">\u25b6 What is the maximum input speed for the EP-PL\/PF series?<\/summary>\n<div style=\"padding: 14px 18px; font-size: 14px; line-height: 1.7; color: #444;\">The EP-PL\/PF series is rated for a maximum input speed of 3,000 rpm for continuous operation. Short-duration peak speeds up to 6,000 rpm are permissible on single-stage units during acceleration and deceleration phases. Noise levels and bearing temperatures should be monitored if sustained operation above 3,000 rpm is planned. For applications requiring higher sustained input speeds, consider the EP-HAB high rigidity planetary gearbox series which offers enhanced bearing capacity and torsional stiffness.<\/div>\n<\/details>\n<details style=\"border: 1px solid #e8eef4; border-radius: 6px; margin-bottom: 10px; overflow: hidden;\" open=\"open\">\n<summary style=\"padding: 14px 18px; cursor: pointer; font-weight: 600; color: #0a1628; background: #f5f8fc; font-size: clamp(14px,1.5vw,16px); list-style: none;\">\u25b6 Does Korea Ever-Power offer custom shaft and coupling configurations?<\/summary>\n<div style=\"padding: 14px 18px; font-size: 14px; line-height: 1.7; color: #444;\">Yes. The EP-PL\/PF series supports six input coupling types: OP1 (integral hoop clamp, standard), OP2 (split type hoop clamp), OP3 (integral with keyway), OP4 (reinforced for frequent reversing), OP5 (keyway only), and OP6 (custom adaptor). Output shafts are available in S1 (smooth), S2 (keyed), and T (custom specification).

Internal gear quality, bearing class, and torsional stiffness are also upgraded in the PBL\/PBF series. If your application tolerates \u22648 arcmin and does not require washdown or dust-proof protection, the EP-PL\/PF offers significant cost savings. For semiconductor, laser, or medical applications where \u22645 arcmin and environmental sealing are mandatory, the EP-PBL\/PBF high precision planetary gearbox is the recommended upgrade path.<\/div>\n<\/details>\n<\/div>\n<p><!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 FINAL CTA \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"background: linear-gradient(135deg,#0a1628 0%,#1a3a5c 100%); border-radius: 10px; padding: clamp(24px,4vw,40px); text-align: center; margin: 36px 0 20px;\">\n<div style=\"font-size: clamp(20px,2.8vw,28px); font-weight: bold; color: #fff; margin-bottom: 10px;\">Specify Your EP-PL\/PF Planetary Gearbox<\/div>\n<p style=\"color: #8ab4d9; font-size: clamp(14px,1.6vw,16px); max-width: 640px; margin: 0 auto 20px; line-height: 1.7;\">Send us your motor model, required ratio, output torque, and duty cycle.
