Bottom clamping cam units GN 918.6 are fitted with a rotating helix. They allow rapid and safe clamping and releasing with a relatively long movement and high clamping force.
The ball lever handle is linked with the clamping mechanism via mating serrated parts, thus allowing an individual positioning of the ball lever handle.
Bolt and washer are matched to allow an effortless release from the clamped position. The clamping bolt can also be used with T-slot nuts on machine beds.
Bottom clamping cam units offer the advantage that they can be rotated away from the clamping area after release.
Bottom clamping cam units can also be used as stepless adjustable end stops. If the washer is removed, the bolt can be clamped direct to its support. Spherical clamping bolts with flat faced ball GN 605 are recommended for use with these clamping bolts.
