Description & Advantages

NS-249 bearing ring with wiping function type FAI is mainly used on piston rods. It allows space-saving construction due to its integrated wiping function. It provides guiding and bearing surfaces between rod and housing and prevents metal to metal contact between them. The bearing ring FAI consists of an extremely abrasion -resistant and low friction POM-PTFE Bronze compound. It can be used for hydraulic oil with a mineral oil base, for water-oil emulsions and for fire resistant fluids as well as compressed air. It has a U-shaped cross-section and is split with an angled butt joint. It can be spirally compressed in wards for fitting into the rod housing where it springs back out into corresponding installation grooves The bearing groove arrangement secures it against axial movement.
