Easy assembly and disassembly

Both actions take place by locking and unlocking the clamping screws with common tools.

The use of a torque wrench is only necessary when a more precise torque is required.

Superior holding power

The action of the clamping cones creates shaft clamping torque superior to a normal keyed hub.

Overload protection

When the pre-set torque is exceeded locking device will slip, preventing the connected elements from being broken.

Note: Locking units are not friction couplings, so excessive slip will cause damage.

Easy adjustment

Combining the locking device design of smooth cone action with superior holding power, the hub can be clamped at any position along a shaft, eliminating the need for lock washers, spacers , stop rings, etc.
