Product Display

Compact Design with High Torque Density

The WHJ series features a compact, lightweight structure that delivers high torque in a small footprint. With rated torque options from 3 N·m to 60 N·m, it helps reduce overall robot weight and save installation space.

High-Precision Dual-Encoder System

Equipped with a 16-bit incremental encoder and an 18-bit absolute position encoder, the WHJ series provides precise position feedback for accurate motion control and reliable positioning in robotic applications.

Integrated Design with Hollow Routing

The integrated joint design simplifies robot assembly, while the hollow shaft provides space for internal cable routing. This helps create a cleaner mechanical layout and supports compact, modular robot structures.

Reliable Control and Flexible Integration

Supporting CAN FD communication and multiple rated torque options, the WHJ series offers flexible integration for different robotic joint requirements. Selected models feature soft braking or pin-type braking to meet different application needs.
