FB05

DMR Seals piston guide ring / wear ring profile FB05 has the addition of a locating ring on the inside diameter to reduce axial movement in reciprocating applications.

Piston guide ring profile FB05 is a tight tolerance ring which is commonly used in pneumatic applications where precise piston movement is critical. This wear ring can be manufactured from several of our high-performance thermoplastic materials to provide precise clearance control and low friction operation.

The tight tolerance control on the FB05 profile ensures excellent bearing contact which helps minimise and control misalignment while the rod is under static or dynamic load. This profile is split for ease of installation and normally locates on the piston in the centre of two single acting (uni-directional) piston seals working in a back-to-back configuration.
