Servo Belt Stand

The PushCorp SBS91 Servo Belt Stand combines compliant force control with a high-torque 16.5 hp [12.3 kW] servo motor. This precise force and constant speed allows you to achieve unprecedented levels of quality and consistency.

The SBS91 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.

  • Grinding (casting gates, weld beads)
  • Deburring (parting lines, chamfer)
  • Polishing (glass, wood, metal)

The contact wheels of the SBS91 Servo Belt Stand are 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. The belt media is tracked remotely keeping personnel out of the workcell during operation. Easily removable contact wheels allow widths of 1", 2", 3", and 4", plus a wide range of different rubber hardness. Changing the belt media is a snap with pneumatic tension and conveniently positioned manual valves.
