WITTENSTEIN AG AC20001394 Shrink Disk Gearhead

The WITTENSTEIN AC20001394 Shrink Disk is a precision-machined shaft-to-hub clamping device used in industrial motion control and power transmission to secure torque transmission between servo gearheads and rotating machinery, delivering a backlash-free shaft locking in servo gearbox assemblies, robotic automation systems, CNC equipment, and other continuous-duty industrial installations. It is mounted on the shaft for gearhead size 140, supports up to 30 Nm of torque, uses a friction-based locking system to create a secure, low-backlash mechanical connection, and is engineered for continuous service in demanding manufacturing environments. Part of the WITTENSTEIN line, this unit carries secondary reference 240432 and is commonly replaced by Ringfeder RFN Series Shrink Disk, Tollok TLK Series Locking Assembly, and Fenner Drives Trantorque Keyless Bushing for retrofit or replacement projects in servo gearboxes and automated machinery.
