Self-Aligning Bearings

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.

Double-row angular contact ball bearings are used in applications when heavy radial, thrust or combined loads demand axial rigidity of the shaft are required. This is similar to a duplex pair of single- row bearings due to its two rows of balls and angular-contact construction, which provide greater axial and radial rigidity than can be obtained by using a single-row radial bearing. We manufacture these ball bearings with a minimum bore diameter of 3 mm to a maximum outer diameter of 47 mm.

Although single row radial bearings are designed primarily to support a radial load, they perform relatively well under thrust or combined radial and thrust load with the added advantage of low noise, vibration, and drag torque. The internal architecture and cage selection can be designed to meet the specific needs of the application, from high speed to high load. Thin section deep groove ball bearings have a small radial cross-sectional thickness that are used when compactness is required. We manufacture deep groove ball bearings with a minimum bore diameter of 3 mm to a maximum outer diameter of 47 mm.

These track rollers offer the same features of a single row track roller with the added benefit of heavy radial, thrust or combined loads. Yoke-type track rollers are single or double-row units mounted on shafts or studs. Similar to the single row track roller, we can customize the running surface to meet the specific requirements of the applications. Cam rollers are similar in their construction to single and double-row support rollers, except that the raceway is formed by a heavy-section roller stud with a fixing thread. The most common running surface profiles can be found on the Special Profiles page under Technical Parameters.
