Product Description
GN521.6 Disc Handwheel, Plastic, Stainless Steel Bush and Retracting Mechanism
The handle in the handwheels GN 521.6 is locked in a conical bore in the operating position.
For reversal, it must first be pulled from the cone in axial direction.
A pressure spring holds the handle in both positions. When swung out, it automatically engages again.
The cover conceals clamping elements, e.g. countershaft pulleys, as well as protruding and recessed shafts. For mounting, the cover is pushed in by hand. For dismantling, the cover can be raised and taken off by applying moderate pressure in the rim of the cover.
