82 Aero Camino, Goleta, CA (805) 685-1029 www.bell-everman.com DATA SHEET ServoBelt Rotary Stage Precision rotary motion in an easy-to-integrate package.

  • Big Through-hole, Small Package. Available in 50, 100 and 200 mm through holes and profi les under 67-mm, these belt-drive stages are easy to integrate into tight machine envelopes.
  • Direct Drive Performance. Designed for NEMA 23 and 34 motors, the belt-drive stages offer speeds up to 1,000 rpm, continuous torque to 6.6 N-m and accuracies down to 0.27 arc-sec with Renishaw ring encoders or tape scales for partial rotation.
  • Application Flexibility. ServoBelt Rotary supports both continuous rotation and variable indexing applications.
  • Robust Bearings. ServoBelt Rotary incorporates large bearings for its size, imparting moment and load capacities far in excess of its usual application requirements. This excess load capacity translates into virtually limitless bearing life. Lubed-for-life, full duplex, preloaded angular contact bearings.
  • Cost Effective. ServoBelt Rotary offers an economical solution for a variety of medium-duty rotary motion jobs such as driving carousel tables on packaging and assembly machines and providing fourth-axis rotary motion for laser cutting and mini CNC machines. continuous rotation and variable indexing applications.
