Pneumatic shaft-locking clamps are designed for quick change applications. They provide secure clamping of sliding shaft and spindle after position adjustment of parts and units in the machinery. Spring clamping occurs when air is removed, and unclamping when air is provided. Spring clamping and pneumatic unclamping mechanism prevents the decrease of clamping force by air leakage. PSLC-M-S type can be used in combination with sensors to detect the clamping condition. (Sensors supplied separately by customer). Brackets are available to mount a sensor to the PSLC-M-S type clamps (sold separately). Pneumatic clamp body and cover are made from 5052A anodized aluminum. Clamping shaft is made from 1045 steel with an electroless nickel-plated finish.
