GN709.6 Clamping Pad, Adjustable, with O-Ring, Steel
These adjustable clamping pads, GN 709.6, are also used in jig and fixture construction, for example for clamping workpieces, as movable bearing surface or as a back stop.
The swivel mounted ball compensates for uneven and non-parallel contact surfaces by as much as 10°. It is also secured against further twisting.
The O-ring holds the ball in position and prevents dirt from penetrating, resulting in a long service life and constant mobility.
