Track Rollers

Track rollers are rolling bearings that can be used in special designs and applications. They can be mounted on axles, at the same time the outer ring can roll on a counter roll, curve or plane. The thick-walled, usually crowned outer ring is suitable for high radial loads and can compensate misalignments with respect to the raceway.
