ST Torque Rotating Unit

Rotate and pivot with precision and extremely high dynamics

The ST torque rotating unit, featuring a direct drive and absolute encoder, is exactly the right tool to use when fast, precise and highly dynamic rotating, tilting and gripping motions are required. Whether for feeding or orienting parts, in the process, as a swivel module for grippers or as a replacement for standard servomotors with planetary gears, the ST rotating unit provides the optimal solution.

Compatible control packages: W.A.S. 2 COMPACT, W.A.S. 2 SCALABLE
