GN 709.8 clamping pads are used in jig and fixture construction, for example for clamping workpieces, as a movable bearing surface or as a stop. The swivel-mounted ball compensates 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 mobility.
