Plain BushesPlain 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.
