Double row track roller bearings
 
 

TCB track rollers are based on deep groove ball bearings or double row angular ball bearings, which have a thick-wall outer ring with crowned or cylindrical outside surface. The bearings are sealed and filled with grease.

 

In contrast to standard ball bearings, where the outer ring is supported over its entire outside diameter surface in the bore of a housing, the outer ring of the tracker rollers has only a smaller contact area with the surface against which it runs. The deformation of the outer ring caused by this limited contact alters the force distribution in the bearing and thus has an influence on load carrying ability. The ability to carry dynamic loads depends on the requisite life, but the value of the maximum dynamic radial load Fr must not be exceeded.
