Overview Bearing Elements

The internal and external elements safely absorb transverse forces and ensure perfect conduction on the piston and cylinder head. The specially developed wear-resistant and durable material compound has the lowest coefficients of friction even in dry running. Thanks to the patented tongue-and-groove profile geometry, the distance between the metallic components is increased to a maximum. Seals can be supported directly on these elements and are protected against gap extrusion. Damage to the cylinder barrel and the rod due to metallic contact is a thing of the past - this results in increased operational reliability and a noticeably longer service life.
