Track Rollers are self-retaining ball bearings with a similar design to deep groove and angular ball bearings. They consist of outer rings with spherical or cylindrical shell surfaces, inner rings and ball and cage assemblies retained by polymer cages. This design allows stable positioning of the balls and low-friction movement along the axis. They are mounted on axles to ensure precise operation and high efficiency.

Track rollers are widely used in cam gears, guideways, conveyors and linear guidance systems. Their robustness enables precise guidance and movement along specified paths. In addition to high radial forces, they can also support axial forces in both directions.

Sealed Track Rollers are used in environments exposed to dust and dirt to prevent the ingress of dirt and moisture. This improves the safety and service life of the rolling elements and the track rollers remain functional for longer. The selection of the appropriate design depends on various requirements, such as sealing efficiency, temperature and chemical resistance of the seals.
