GAM EPL Inline Planetary Gearboxes

The GAM EPL Series is a family of inline planetary gear reducers engineered for precision, performance, and versatility in servo-driven automation systems. With ratios from 3:1 to 1000:1 and frame sizes ranging from 50 mm to 155 mm, the EPL line offers a balance of torque density, compactness, and affordability. Its modular design supports multiple output configurations—including metric, NEMA, flange, and hollow output styles—making it adaptable to both new builds and retrofit applications.

Each EPL gearbox is built with hardened precision gears for quiet, smooth operation and long service life. Whether integrated into linear actuators, conveyors, or packaging machines, the EPL series delivers consistent motion control and low backlash performance for demanding automation environments.


EPL Series Key Features:

  • Inline planetary design for high torque density and compact integration
  • Ratios available from 3:1 to 1000:1
  • Low backlash for precise motion control
  • Metric and NEMA output options for design flexibility
  • Heavy-duty bearings and optimized gear geometry for durability
  • Suitable for servo motors and linear actuator assemblies

GAM EPL Series Comparison:

Model Output / Mount Ratio Range Frame Sizes Key Features
EPL-W Metric shaft output 3:1–1000:1 50–150 mm Heavy-duty output bearings and robust performance for general automation applications.
EPL-X (NEMA) NEMA shaft output 3:1–1000:1 NEMA 17–56 Designed to fit standard NEMA motor sizes for simplified system integration and retrofits.
EPL-H Linear Mount Hollow output 3:1–1000:1 Zero-backlash clamping ring; mounts directly to off-the-shelf linear belt or ball screw modules.
EPL-A Metric shaft output 3:1–1000:1 50–155 mm Matches output dimensions of many common inline gear reducers for easy interchangeability.
EPL-F Flange output 3:1–1000:1 64–110 mm Compact flange-mount design offering high stiffness and minimal footprint.
EPL-UH Hollow output with actuator adapter 3:1–1000:1 64, 84, 118 Includes motor and actuator adapters; ideal for linear actuator integration and modular assemblies.
