GMT make Power Operated Pneumatic Front end Chuck.
GMT make Power Operated Pneumatic Front end Chucks are designed to utilize in full, the spindle bore for bar/pipe work. This design avoids rear mounting of the actuating cylinder and necessary draw bar connections.
Principle of Operation
Power Operated Pneumatic Front end Chuck has two special rubber seal rings on the distributor assembly. The special seal ring is compressed when the chuck is pneumatically actuated to facilitate opening and closing of chuck jaws. Once the job is clamped due to venting of the air supply, the special seal rings lift to ensure rotation of the chuck. This design eliminates wear on the special seal rings.
