The precise self-centring action of the GN411 provides solid stable clamping of workpieces with uneven or irregular external surfaces
The precise self-centring action of the GN411 provides solid stable clamping of workpieces with uneven or irregular external surfaces - such as castings.
GN411 clamps are available to accommodate bores from 12 to 102mm.
Operation is manually by means of clamping screw or by hydraulic/pneumatic activation.
The unit contains a circular cage with three or six hardened balls (depending on size of unit), which are forced outwards over an ingenious double cone ramp system, thus exerting an outward thrust and gripping the workpiece securely.
For delicate materials the GN411 can be supplied with barrel shaped hex section segments in place of balls.
These offer a more gentle surface gripping action by spreading the load over a larger area. Request a free brochure from Elesa (UK) ...
