Belt-tracking Rollers

Steel clamped or monobloc rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded shaft protrudes from only one end of the tube.In belt conveyors, they are vertically mounted in pairs at the edges of the rubber matting, with the function of restricting any lateral slipping. They are installed on self-centring stations with the same function.The technical characteristics of Series 6 rollers are those of the relative base rollers.Other finishes, see page 30.

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.

A specialized design combines an external cylinder with a cylindrical raceway and balls that are incorporated in the retainer, making rotary and linear motion in the axial direction possible simultaneously with rotational motion. Small Rolling Frictional Resistance Incorporating a ball with high accuracy into the precisely polished external cylinder results in small rolling frictional resistance and extremely smooth rolling motion together with reciprocal motion. Low Inertia Since the retainer has high rigidity and is lightweight, it has low motion inertia, making it suitable for rolling motion and reciprocal motion in highspeed operations. A Variety of Models Standard and heavy load models are available, each with different load ratings, and each offered with or without seals. It is easy to choose the right product based on the specifications of your machine or device.
