Clamping Elements
PN63-20-3-4B

Rod clamping with maximum clamping force

Pneumatic Rod Clamping
Holding force 849.78 lbs
Holding torque 309.78 in-lbs

Immediate clamping in case of loss of pneumatics: suitable for rods with diameters of 20 mm to 40 mm (0.79 to 1.57 in), the clamping elements LOCKED PN absorb the forces axially and rotationally. With holding forces of up to 8,093 lbs. (36,000 N), they reach or exceed the levels of hydraulic clamps, with lower system costs.

Alongside clamping in both directions of motion, the LOCKED-Family PN also surprises with its compact design. They need less installation space and enable short rod lengths. Many users appreciate the modular system. It allows several segments to be stacked so that the necessary clamping force can be attained for every application.
