The Dunkermotoren PLG 63 HT Series Planetary Gearbox is a high-torque, industry-grade solution designed for demanding motion control applications where strength, reliability, and compact integration are key. With a hardened steel ring gear and high-efficiency gear design, the PLG 63 HT is engineered for smooth operation and long-lasting performance in automation, robotics, mobile equipment, and heavy industrial systems.

Available in 1-, 2-, and 3-stage configurations, this gearbox supports a broad range of reduction ratios from 3:1 to 350:1. It delivers continuous torque output up to 58 Nm and peak acceleration torque up to 88 Nm. Emergency stop torque ratings reach 169 Nm, ensuring robust performance in dynamic applications.

Featuring IP65 protection (excluding the output shaft when used with BG 66 motors), the PLG 63 HT is built to withstand harsh environments. The double ball-bearing output shaft enables axial and radial loads of up to 800 N, while a maximum backlash as low as 29 arcmin ensures excellent positioning accuracy.

With up to 90% mechanical efficiency in single-stage versions, lifetime lubrication, and compatibility with both S1 (continuous) and S8 (cyclical) duty cycles, the PLG 63 HT offers long service life with minimal maintenance.

This gearbox is an ideal choice for compact drive systems requiring high torque, long durability, and industrial-grade reliability.
