Single Acting Pull-Down Clamp, Spring Return, Manifold Mounted
Special Use Clamps
- 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.
- Manifold oil supply only.
- Body of burnished tempered steel with case-hardened ground pistons for long life.
Jaws and pistons are connected by a joint that avoids the introduction of a bending moment to the piston and extends clamp life. Fastened with two mounting bolts from above and four bolts from the bottom to insure maximum hold within operating limits.
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 mµ Ra.
NOTE: Do not overstress mounting bolts. Observe maximum permissible torque. Maximum operating pressure 400 bar (40 MPa).
