Shaft Clamping Elements, also known as Power Locking Assemblies, by means of frictional forces, provide connection of all types of transmission equipment to their respective shafts, enabling transmission of both torque and axial thrust loads. Precision tapered thrust cones within the clamping elements create high pressure between shaft and hub to securely fasten pulleys, sprockets, gears, impellers, propellers etc.

These keyless lock assemblies are shaft-to-hub frictional locking devices that provide easily adjustable and releasable mechanical shrink fit. They offer simple installation, increased shaft strength and high torque transmission capacity.

HOLK Bearing offers a comprehensive range of different types of clamping elements to meet individual needs.
