Technical Specifications

Description & Advantages

 

The NS-247 bearing type FA is mainly used on pistons. It provides guiding and bearing surfaces between piston and cylinder tube and prevents metal to metal contact between them. The FA 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 easily expanded for fitting into corresponding installation grooves on the piston. The U-shaped groove arrangement secures the bearing 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.
