Technical Specifications

Description & Advantages

 

NS-248 FI bearing ring type FI is mainly used on piston rods. It provides guiding and bearing surfaces between

rod and housing and prevents metal to metal contact between them. The FI 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 inwards for fitting into the rod housing where it springs back out into corresponding installation grooves. The bearing groove arrangement secures it against axial movement. The bearing rings can be used as single rings or multiple rings arranged adjacent to each other. The number of bearing rings depends on the expected side loads. The butt joints in adjacent bearings should be staggered.
