DMR’s FB09 profile is a modification of our standard FB08 rod working guide ring which incorporates a scraping / wiping edge on the non-pressure side to allow it to be utilised in heavy duty applications where the removal of heavy particles of mud or ice may be present.

As per our FB08 guide ring the FB09 is a tight tolerance ‘U’ shaped rod working guide ring / wear ring which is produced with additional retaining lugs to help prevent axial movement while the rod is reciprocating under pressure. It can be manufactured from several 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 ensures excellent bearing contact which helps minimise and control misalignment while the piston is under static or dynamic load which helps to significantly increase seal life when compared to high volume moulded rings.

This profile is provided split for ease of installation and is commonly utilised in multistage hydraulic rams where space is limited and where metalwork clearance gaps need to be quite large.
