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.

New seals for more efficiency

The seal concept was also revised at the same time as the optimized internal design. INA track rollers LR52 and LR53 are supplied with HRS seals as standard or with the new Z seal as an option. Both seals offer significantly higher sealing action compared with the previous version.

X-life – premium quality for rolling bearings

The improved INA X-life LR52 and LR53 track rollers feature numerous design details that result in up to 10 % higher dynamic load ratings and up to 15 % higher static load ratings.
