After the clamping process, the contact surfaces of clamping pads type BR and RR automatically reset themselves to their initial position. This prevents the bearing from jamming in an inclined position when the workpiece is inserted.
The bearing can be rotated by a maximum of 9° and is secured against further rotation.
