Precision rotary motion in an easy-to-integrate package

ServoBelt Rotary is a series of compact, high-torque rotary stages that offer through hole size and speed comparable to direct-drive rotary tables costing thousands more.

• Big Through Holes, Small Package. Available in 50-, 100- and 200-mm through holes and profiles under 67-mm, these belt-drive stages are easy to integrate into tight machine envelopes. The large through holes leave plenty of room optics, utility connections, slip rings or more.
• Direct Drive Performance. Designed for NEMA 23 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. Motor-to-table ratios optimized for intertia matching at high speeds.
• Robust Bearings. ServoBelt Rotary incorporates large angular contact bearings for its size, imparting moment and load capacities far in excess of its usual application requirements. This excess load capacity, along with a lubed-for-life design, translates into virtually limitless bearing life.
• 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.
