RSF Supermini Series Brushless Servo Actuator
|
RSF-3C (standard)
RSF-5B (standard)
RSF-5B (With Brake)
|
The RSF Supermini Series is an ultra-miniature brushless servo actuator that delivers high torque and precision by combining a zero-backlash Harmonic Drive® gearhead with a high performance servo motor. The output shaft is supported by a robust 4-point contact bearing which often allows mounting of the load directly to the shaft of the actuator. Performance matched servo drives are also available to deliver the full capabilities of these high performance actuators.
Machinery and equipment designs requiring high torque with limited available space will benefit from this product.
