Schaeffler track rollers now available in premium X-life qualitySchaeffler is extending its premium quality X-life product family with a new range of high-performance track rollers that offers a significantly higher load-carrying capacity and a longer rating life than its predecessors.

The redesigned LR52 and LR53 series of track rollers are new additions to Schaeffler’s X-life product family. With an increased dynamic load rating of 15 per cent compared with competitors’ products, combined with a speed limit increase, the LR52 and LR53 X-life track rollers are the claimed to be the highest performing track rollers currently available on the market.

Both series are available exclusively in premium quality X-life standard. As the external dimensions remain the same as their predecessors, the LR52 and LR53 X-life track rollers are direct replacements for existing track rollers, with no modifications required to the customer’s application.

Upgrading the track rollers to X-life quality required improvements to the internal design of the bearing. The LR52 and LR53 series incorporate a variety of new design features that result in an increased dynamic load rating of up to 10 per cent and an increased static load rating of up to 15 per cent. These improvements also result in significant increases in the bearing rating life.

Both series are offered with DEHP-free HRS seals as standard or with improved steel sealing shields (Z) as an option. Customers can also choose between an optimised polyamide cage or a rigid, robust steel cage.

What is a track roller?

Track rollers are self-retaining double-row units with particularly thick-walled outer rings. In addition to high radial forces, these bearings can also support axial forces in both directions. The outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where they are inclined in relation to the mating track, ensuring reducing edge loading if misalignment occurs.
