DMR Seals FB01 profile is a tight tolerance guide ring / wear ring which can be manufactured from a number of our high-performance thermoplastic materials to provide precise clearance control of mating metallic hardware members in fluid power or pneumatic systems.

The tight tolerance control on the FB01 profile ensures excellent bearing contact which helps minimise and control misalignment while the piston or rod is under static or dynamic load which helps significantly increase seal life when compared to high volume moulded rings.

FB01 is supplied either in solid format or split for ease of installation and can be supplied with spiral grooves on the main contact surface to prevent entrapped pressure between the seal and the guide ring itself. The addition of these grooves can also help eliminate jet-erosion, which is where the high-pressure fluid of the hydraulic system is forced through the localised split in the ring and damages the seal.
