Technical information on plain bushes
Metal/polymer composite plain bushes, maintenance-free
Maintenance-free plain bushes are used for rotary, oscillating and linear motion. These plain bearings are bearings for very small radial or axial design envelopes. These products are available as bushes and flanged bushes. The bushes are available in metric sizes and in inch sizes. They are rolled from a cut section of strip and have a butt joint over the entire width of the bearing.
The plain bushes are supplied with either steel backing or bronze backing. Bearings with a bronze backing have high corrosion resistance and very good thermal conductivity and are antimagnetic.
If the plain bushes are to be used in the aerospace sector or in the food or pharmaceuticals industry, please contact the Schaeffler engineering service.
Maintenance-free plain bearing material
For maintenance-free metal/polymer composite plain bearings from Schaeffler, the sliding material E40 and E40-B is used. The basis of the dry lubricant is polytetrafluoroethylene PTFE with embedded chemically non-reactive additives.
