Reconditioning
Features
Many bearings are replaced completely in the course of maintenance work although they could be restored to almost as-new condition by means of reconditioning. In the case of maintenance-free spherical plain bearings with ELGOGLIDE, this may represent an economically attractive alternative, ➤ Figure.

Advantages
The advantages for the customer are as follows:
- longer useful life due to high quality maintenance work
- short downtime periods due to swift implementation of the maintenance process
- little mounting work, since the bearings are returned in a condition ready for mounting
- reduced maintenance costs due to preventive maintenance.
Reconditioning level
Before reconditioning, the bearing is dismounted, cleaned and examined. The processing steps required are established and a proposal is prepared. The scope of reconditioning of plain bearings is subdivided into levels, see table.
Level I to Level II
