Piston guide ring, type KF
The type KF piston guide ring prevents contact between sliding metal parts and absorbs transverse forces. It is made of PTFE-carbon or PTFE-bronze as standard and offers high wear resistance, good sliding behaviour and excellent chemical resistance to various hydraulic media.
Guidance and protection with high-quality piston guide rings
The type KF piston guide ring prevents sliding metal parts from touching and absorbs the transverse forces that occur. As standard it is made of PTFE-carbon or PTFE-bronze; other materials are possible depending on the application.
Thanks to its very good media resistance, the piston guide ring can be used with mineral oil-based hydraulic fluids, environmentally friendly hydraulic fluids, water-oil emulsions and fire-resistant hydraulic fluids.
It offers excellent sliding behaviour, good emergency running properties and high wear resistance. It also helps to dampen mechanical vibrations, ensuring quiet and long-lasting operation of the cylinder components.
