Rotation is generated by a cam-bushing design that has been tested to millions of cycles. Attaching a clamp arm to the cylinder (Bimba EFG1), the actuator becomes a clamp for light-duty holding applications. The twist clamp is available in four bore sizes, 25, 40, 50 and 63 mm. The clamp can exert up to 600 lb of force with a 140-psi air supply.
