Quick release shaft collars GN 704 are clamped by reducing the slot height using an eccentric lever.
That allows the collars to be adjusted easily and quickly without tools.
The aluminum design delivers low 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 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.
