Design:

Cylinder body from steel, hardened. Support pin with internal thread case hardened and ground. Wiper to protect against dirt and cooling water. Internal parts from stainless steel. Oil supply through threaded connection or an O-ring connection on the underside.

Application:

The support element is used as an extra support to prevent sagging and vibration of a workpiece.

Features:

Element with high load capacity and low height. Oil pressure: The plunger is retracted in the normal position. When pressure is applied, the support pin advances with a weak spring-applied force against the inserted workpiece. The spring force varies with the pin stroke. As the hydraulic pressure rises, the support pin is hydraulically clamped. When the pressure is released, the support pin returns to the normal position. Very high repeatability ensures optimum production quality. The basic body can be removed for direct installation of the screw-in cartridge.

Note:

Support pin must be protected against the entry of dirt and splash water by fitting a set screw or plug. When placing into operation, ensure that all air is bled from the system. Failure to do so can cause destruction of the clamping element by the escaping diesel effect.
Connections P1, P2 and the O-ring connection are all connected. Each can be used as an oil connection. To achieve a controlled clamping sequence, there is the option of screwing the sequence valve 6918-XX-XXX directly into threaded connection P1. The surface finish of the O-ring connection must be Rz 6.3 and flatness must be 0.08.

To be able to absorb machining forces, the supporting force should be matched to the clamping force.
The supporting force should always be at least twice as high as the clamping force.
