Technical information on plain bushes

Metal/polymer composite plain bushes, maintenance-free

Features

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.

ATTENTION
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.

Metal/polymer composite plain bushes, low-maintenance

Features

Low-maintenance plain bushes are used for rotary, oscillating and linear motion. These plain bearings are bearings for very small radial or axial design envelopes. They are rolled from a cut section of strip and have a butt joint over the entire width of the bearing.

ATTENTION
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.

Low-maintenance plain bearing material

For low-maintenance metal/polymer composite plain bearings from Schaeffler, the sliding material E50 is used. The basis of the sliding layer is polyoxymethylene POM.

Plain Bushes

Plain bushes are used not only for rotary and oscillating motion but also for linear motion with short or long stroke lengths.

In the case of maintenance-free, polymer composite plain bearings with the sliding material E40, lubrication is not necessary at any point during the operating life due to the use of PTFE as a dry lubricant.

The low-maintenance, polymer composite plain bearings with the sliding material E50 receive an initial lubrication at the start of operation. Since the sliding layer has lubrication pockets, this initial lubrication is sufficient in most cases.

In addition to the polymer composite plain bearings, there are also plain bushes with Elgoglide and Elgotex filament wound bushes.

The maintenance-free wound bushes made from filament composite are non-metallic and thus resistant to numerous media. For use in water, Schaeffler has developed the sliding material Elgotex-WA.
