Guide Rings

Guide rings absorb lateral forces in hydraulic cylinders and ensure precise guidance of the pistons and piston rods. They prevent metal-to-metal contact, reduce friction and wear, and extend the service life of the sealing system. Available as ready-to-install guide rings or by the meter, made from high-performance synthetic and fabric composite materials—for a variety of loads and operating times.
