Track Rollers
Track rollers are available in single- and double-row versions. They are optionally available with sheet steel covers or abrasive sealing discs made of acrylonitrile-butadiene rubber (NBR). Single-row track rollers are based on deep groove ball bearings, while double-row track rollers are based on the principle of double-row angular contact ball bearings. This type of bearing can absorb high radial forces and axial forces. Depending on the design, the outer ring surface is crowned or cylindrical.
