Product description

Unlike thrust bolts or clamping screws, quick release shaft collars GN 704 generate locking force on the shaft via an eccentric lever. This quick release design allows the collars to be set or adjusted rapidly and without tools. The aluminum design results in low mass inertia values.

The specified tightening torque of the screw is a recommended value with which the collar clamped to a shaft (with closed eccentric lever) is capable of reaching the specified axial load capacity. The details on the axial load capacity are non-binding guidance values and do not constitute a warranty of characteristics.

Keeping the friction surface of the eccentric lever slightly greased will help to prolong the useful service life.
