Track rollers

Track rollers—also referred to as idler rollers—are motion transmission components designed to work with all varieties of tracks. They are used in conveyor systems, cam drives, and a wide range of similar material handling systems. Regardless of the material or machine, these components play a critical role in track and rail operations. When selected, employed, and maintained properly, they facilitate system operations, allowing for greater speed and efficiency. Single row track rollers are available with spherical outer ring running surfaces or cylindrical (or flat) outer ring running surfaces. View our page of Special Profiles found under Technical Parameters for some of the more common profiles on the running surface.

Our KIS track rollers are available as self-retaining, single or double row ball bearings with particularly strong outer rings. In addition to high radial forces, they also absorb axial forces in both directions. Track rollers are characterised by their robust construction featuring particularly thick-walled outer rings with a crowned outer surface (alternatively with a cylindrical outer surface or outer profile). They are designed to carry high radial loads and also tolerate axial loads that can arise due to minor misalignments, skewing or short-term start-up shocks. The assembly is constructed with a fixed inner ring mounted on axles. In this case, the track rollers are not installed in a housing bore, but are supported on a flat raceway (mating track). To ensure a reliable seal, the track rollers are fitted with a lip seal or cover discs on both sides. This prevents the ingress of dirt, dust and other contaminants while maintaining lubrication inside the bearing.
