Keyless Shaft Hub Locking Element & Shrink Discs

Mecaloc Keyless Shaft Hub Locking Element & Shrink Discs are shaft hub locking devices once mounted offer a perfect interference fit, with the case of a slide fit during assembly and disassembly to give a backlash free torque transmission. When the locking screws are tightened, a radial pressure is produced through the taper wedge cross-section of the device to expand into the hub and to shrink on to the shaft to cause a frictional locking between the shaft and the hub. Mecaloc locking devices offer the most advanced solution in the field of locking elements of transmission equipment as it combines the precision of the transmission of synchronous motion with the high power that can be transmitted by a friction coupling.
