Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings. These bearings can support axial forces in both directions as well as high radial forces. The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided. The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.
INA track rollers LR52 and LR53 – now available in X-life quality
INA track rollers series LR52 and LR53 are now available in X-life quality. They can now transmit higher radial loads and have a longer rating life thanks to the optimized internal design.
The external dimensions of the new bearings have not changed, which means they can replace earlier bearings without difficulty.
