Spring Clamping Cylinders

Applications

Unpressurised long-term clamping of moveable machine parts, dies, fixtures, pallets and workpieces

Function

The force of the spring clamping cylinder is mechanically transmitted to the tie rod or the clamping spindle by a pre loaded Belleville spring assembly. The hydraulic connection is only required for unclamping the clamping cylinder.

Special features

• large choice of clamping forces
• long service life by low-friction Belleville springs placed between hardened and ground thrust washers
• piston secured against rotation
• oil ports radial and axial
• easy installation
