Abstract: When clamping, compressed air within a second chamber (22) of a pneumatic cylinder (12) is discharged and fresh compressed air is supplied to a first chamber (21). Then a pressure of the compressed air within the first chamber (21) and an urging force of a compression spring (25) move a piston (20) leftwards. The piston (20) moves an output rod (26) rightwards strongly through a plurality of engaging balls (34) and a first pressure receiving member (31). When unclamping, the compressed air within the first chamber (21) is discharged and fresh compressed air is supplied to the second chamber (22). Then a pressure of the compressed air within the second chamber (22) moves the piston (20) rightwards and at the same time the output rod (26) leftwards.

Abstract: A clutch and a workpiece support incorporating the same selectively restrict rotation of a rotatable member through the use of one or more rollers that are pinched between the outer surface of the rotatable member and corresponding convergent surfaces disposed on a housing opposing such outer surface. In effect, each roller is interposed between a surface on a fixed housing and an outer surface of a rotatable member such that rotation of the rotatable member rolls the roller toward a converging gap to restrict further rotation of the rotatable member. A biasing mechanism biases the roller toward the converging gap, and a release mechanism is utilized to quickly and efficiently decouple the roller from the rotatable member by biasing the roller in a direction away from the converging gap and thereby preventing the roller from inhibiting rotation of the rotatable member.
