Pull-Down Clamp, Eccentric
Single and Double Acting
- 5-sided machining can be carried out safely without clamp interference.
- Workpiece can be loaded and unloaded by handling equipment.
- Optional oil supply through G1/8 port or manifold connection.
- Disk spring for staged pull-down effect.
- Body, sleeves and draw bar are made of nitride-hardened alloy steel for longer trouble-free life.
- Clamping sleeves are segmented and serrated to form and grip the clamping hole.
- These Pull-Down Clamps also serve as a support surface and “Z” locator for the workpiece.
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 mµ Ra.
Maximum operating pressure 150 bar (15 MPa)
Minimum operating pressure 30 bar (3 MPa)
