Self Centering Internal Clamps - 12061 - 12072
What is...
The Internal Centering Clamp provides autocentric chucking inside both round and square holes, at the simple turn of a hexagon screw. Precise self-centering is achieved through the expansion of the ring of balls which, during clamping, are pressed outward across a precision cone. As the outer diameter of the clamp changes, the balls transmit force between its body and the bore. The Clamps are used in machining and welding fixtures, product assemblies and transfer units.
