Read MoreThe Dunkermotoren PLG 22 HT Series Planetary Gearbox is a compact and high-torque transmission solution, engineered for applications that require precise, efficient, and space-saving power transmission. With a robust steel gear design and multiple reduction ratios up to 3188:1, this gearbox is ideal for robotics, automation, and medical equipment.
Key features include high torque output in a small form factor, with continuous torque ratings up to 2.10 Nm and acceleration torque up to 2.30 Nm. The PLG 22 HT is available in 1 to 5-stage versions, offering a wide range of reduction ratios from 3.75:1 to 3188.65:1. Optional low-backlash configurations are available for applications demanding enhanced positional accuracy.
Designed for reliability, the gearbox features lifetime lubrication and supports axial loads up to 45 N and radial loads up to 135 N (on 6 mm shaft). It operates under S1/S8 duty cycles and maintains high efficiency, even at higher reduction ratios. The IP52 protection rating and optional food-grade or low-temperature lubrication options make it suitable for diverse environments.
For compact installations requiring high torque and durability, the Dunkermotoren PLG 22 HT Series Planetary Gearbox delivers exceptional performance and integration flexibility.
