SFS81 Series

Servo Finishing Stand

The PushCorp SFS81 Servo Finishing Stand combines compliant force control with a high-torque 5.7 hp [4.28 kW] servo motor. This precise force and speed control allows you to achieve unprecedented levels of quality and consistency.

The SFS81 Servo Belt Stand is designed to enable maximum flexibility for any robotic part-in-hand material removal application. Linear travel compliance and excellent access allow a robot to easily manipulate parts over the belt media and perform the following operations.

  • Deburring (parting lines, chamfer)
  • Polishing (glass, wood, metal)

If the application will require more torque, the SFS91 is the largest finishing stand in the series. It features a robust set of linear bearings, can apply 250 lbf [1112 N], and has 62 lb· ft [84 N·m] continuous stall torque.

The SBS81 Servo Finishing Stand is belt driven by a high-torque servo motor. This drive system has a 2:1 reduction that provides plenty of power at the contact wheels.


  • Passive Force Control
  • Servo motor amplifier included
  • Contact wheel position output
  • Accurate media speed control
  • 1.6 in [40 mm] linear compliant stroke
  • All fittings, fasteners, and threaded holes are METRIC
