Guide Rings have the task of guiding the rods and pistons of pneumatic and hydraulic cylinders and preventing direct metallic contact with the cylinder housing. They must have the capacity to absorb strong transverse forces even over a short guide distance while keeping frictional losses low. Depending on the load, a variety of materials have come into use – PTFE, polyamide and fabric-based laminates. The KBS Technologies portfolio offers the right Guide Ring for every type of cylinder, with maximum reliability and longevity.
