Built-in elements

Built-in elements are directly integrated in the fixture body. Such created cylinders can be used as push or pull cylinders. Built-in elements are used on fixtures with narrow spaces, and for applications where mounted standard clamping elements limit the machining space or impede swarf flow.

The built-in elements consist of piston and threaded  bushing. The piston is inserted into the location hole of the fixture. Then the built-in bushing is screwed into the fixture body. The bushing is let-in flush to the housing. Tightening of the threaded bushing is made with a pin-type face spanner. Sealing with minimum leakage at the piston rod is obtained by two independent sealing steps. In addition, a wiper protects against contamination. Sealing in the fit hole is made by an O-ring / back-up ring combination.
