GN 704 Quick Release Shaft Collars Aluminum


Product description


Unlike thrust bolts or clamping screws, GN 704 quick release set collars generate locking force on the shaft via a cam 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.

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