Locking Assemblies

Frictional Locking Assemblies are standard machine elements used to connect shafts and hubs. They are capable of transmitting Torque, axial forces, radial forces and bending moments.

Shrink Discs and Cone Clamping Elements:

Among the frictional Locking Assemblies Shrink Discs and Cone Clamping Elements take an important position. By tightening clamping screws conical surfaces are pulled together generating radial forces


  • Backlash free connections
  • Easy alignment of hub to shaft
  • No notch effect in contrast to keyway connections
  • Compact solutions due to high power density
  • Ideal for reversing operation
  • Reduced costs due to simple shaft and hub geometry
  • Simultaneous transmission of torque and axial force
  • Connections can be released even after long operation time
