G .5
Y BY X DP
Used whenever edge face clamping is desired. Generates straight clamping motion and force along with pull-down clamping force to hold and pull down parts. Pull-down force is approximately 1/3 of the respective clamping force. Standard version with serrated and hardened jaw, complete with mounting bolts (ISO). Optional jaws are available in this section. Oil supply through threaded ports or manifold.

Jaws and pistons are connected by a joint that avoids the introduction of a bending movement to the piston and extends clamp life. Body of burnished tempered steel with case-hardened ground pistons for long life. Fastened with two mounting bolts from above and four bolts from the bottom to insure maximum hold within operating limits.

All dimensions are in mm.
NOTE: Do not overstress mounting bolts.
Observe maximum permissible torque.
Vertical travel should be restricted so that stroke "E" cannot be exceeded. *For manifold mounting, remove the (S) screw and sealing washer and install the included o-ring.
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 µm R a
Maximum operating pressure 400 bar (40 MPa)
