SD High Torque Series

Torque ranges from 173 oz-in to 486 oz-in.

Driver is pre-adjusted for fast and easy installation.

Automatic current cutback at standstill reduces power consumption and heat build up.

Precision manufactured motors on fully automated line ensures the highest quality.

The most compact system available.
