Backing bearings are typically cylindrical roller bearings, with extra thick outer rings and handled in batches per shaft. Backing bearings are preferably handled as complete sets.

In additional to the general remanufacturing process the set of backing bearings total radial cross section (wall thickness) is machined to achieve a very tight cross section variation of all bearings within the batch/shaft. The backing bearing remanufacturing process has been adapted from the general bearing remanufacturing process:
regrind of the outer ring outside surface and refresh the logarithmic profile
assemble, inspect and reclassify section height groups.


Bearing features
High load carrying capacity
Low friction
The optimized internal geometry reduces friction and heat generated by the bearing.
Long service life
The logarithmic roller profile reduces edge stresses at the roller/raceway contact under all load conditions. Also, the logarithmic outer ring outside diameter profile reduces edge loading during operation and contributes to extended service life.
Enhanced operational reliability
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
Effective lubrication
Most  backing bearings have lubrication holes and many have one or more annular grooves in the inner ring to enable lubrication via the support shaft.
