The SHA-CG actuators feature a compact, hollow shaft configuration for design versatility in demanding applications. Ideal for machine tool applications, the SHA Series of brushless actuators provide high torque for fast acceleration and positioning. SHA-CG actuators are composed of a Harmonic Drive® CSG zero-backlash gear combined with a brushless servomotor with an encoder resolution at the output up to 20,971,520 pulse/rev.

The actuators are also available with an optional brake. Positional accuracy better than 1 arc-min and repeatability better than ±5 arc-sec is achieved while delivering up to 3,400 N m of torque. A robust cross-roller bearing allows mounting of large loads directly to the actuator without the need for additional support.

The SHA-CG has a Torque to Weight ratio as much as 8 times greater than comparable housed direct drive motors, and a Torque to Volume ratio as much as 6 times greater. This allows for a more compact and light-weight machine design.

Known for its expert engineering and manufacturing, Harmonic Drive LLC products are relied upon every day for precision motion control.

SHA-CG Specifications:

  • High Accuracy:  Zero-backlash Harmonic Drive® gear reducer
  • Hollow Shaft diameter:   17-45mm
  • Available in 4 sizes, 20, 25, 32, 40
