Spherical Plain Bearing

Category Description

Spherical Plain Bearing

FRB BEARINGS SPHERICAL PLAIN BEARINGS have an inner ring with a sphered convex outside surface and an outer ring with a correspondingly sphered but concave inside surface.

Features :   
FRB Spherical Plain bearings' design makes them particularly suitable for bearings arrangements where alignment movements between shaft and housing have to be accommodated,or where oscillating or recurrent tilting or slewing movements must be permitted at relatively slow sliding speeds.FRB radial spherical plain bearings are available with different sliding contact surface combinations’ i.e. the sliding surfaces of inner and outer rings are made from different materials.There are two main groups: spherical plain bearings requiring maintenance(steel-on-steel) and maintenance-free spherical plain bearings.

Applications :   
Engineer machine, automation equipment, hydranlic engineering equipment,engineer hydraulic cylinder, speed reducers

We have the series below, click to see each details:

1.Radial Spherical Plain Bearings
Radial spherical plain bearings requiring maintenance(steel-on-steel)have hardened sliding contact surface on both rings.The surfaces are treated with molybdenum disulphide and phosphated.It has characteristics of wear-resistance and wear-corrosion.

2.Maintenance-free Radial Spherical Plain Bearings
Maintenance-free spherical plain bearings sliding contact surfaces have three groups:steel-on-PTFE composite material,steel-on-PTFE fabric and steel-on-copper alloy.Dynamice load support capability of steel-on-PTFE composite material.
