Torque limiters are mechanical and electromechanical power-transmission devices that protect machine sections (or workpieces they’re servicing) from overloads, crashes, and damage from jams. Torque limiters work either by slipping or completely disconnecting the drive from the driven load. Some torque limiters of the former type (especially those employing friction plates) are also called slip clutches. […]

Large through-hole angle encoders from HEIDENHAIN offer high accuracy
HEIDENHAIN’s new sealed angle encoders can be used as an alternative to modular angular encoders in motion control machining applications that require a larger than usual through-hole. The new RCN 6000 series absolute sealed angle encoders with integral bearings have an exceptionally large hollow shaft diameter of 180 mm (7.09 in.), allowing larger scale machines […]
