Pneumatically-operated clamping unit PSLC-M

pneumaticspringshaft

Overview
Pneumatic shaft-locking clamps PSLC-M provide rapid, secure locking of sliding shafts and spindles after position adjustment. The unit uses spring clamping when air is removed and pneumatic unclamping when air is supplied, ensuring clamping force is maintained despite potential air leakage. PSLC-M-S variants allow sensor mounting to monitor clamping condition. Body and cover are 5052A anodized aluminum; clamping shaft is 1045 steel with electroless nickel plating.

Product types
