Product Description
Product Description
The standard driving system for a stud type cam follower is a slot, for use with a flat head screwdriver. However, hex sockets are available for higher torquing ability, which is especially useful for eccentric cam followers and those used in blind holes. Hex socket cam followers from most manufacturers eliminate the relubrication capability on that end of the cam follower.
Feature
The outer diameter (OD) of the cam follower (stud or yoke) can be the standard cylindrical shape or be crowned. Crowned cam followers are used to keep the load evenly distributed if it deflects or if there is any misalignment between the follower and the followed surface. They are also used in turntable type applications to reduce skidding. Crowned followers can compensate for up to 0.5° of misalignment, while a cylindrical OD can only tolerate 0.06°. The only disadvantage is that they cannot bear as much load because of higher stresses.

- Material Selection: Track bearings can be manufactured from various materials depending on the specific application’s demands. Common materials include steel, stainless steel, ceramic, and polymer composites. Material selection can be customized to achieve desired properties such as corrosion resistance, high temperature tolerance, or low friction.
- Sealing and Protection: In applications where track bearings are exposed to contaminants, moisture, or harsh environments, customized sealing and protection features can be added. These may include additional seals, shields, or coatings to enhance the bearing’s resistance to dust, water, chemicals, or extreme temperatures.
- Lubrication Options: While self-lubricating or maintenance-free track bearings offer convenience, applications with specific lubrication requirements may benefit from customized lubrication options. Manufacturers can modify the bearing design to accommodate external lubrication systems or provide alternative lubrication methods to meet the unique demands of the application.
- Specialized Load and Speed Ratings: In certain applications, track bearings may need to handle exceptionally high loads or operate at high speeds. Manufacturers can customize the bearing design to offer specialized load and speed ratings to ensure optimal performance and reliability in such demanding conditions.
- Mounting and Attachment Options: Track bearings can be customized with different mounting and attachment options to facilitate easy installation and integration into specific track or linear motion systems. This may include variations in bolt hole patterns, flange designs, or specialized mounting arrangements.
- Track Geometry Compatibility: Track bearings can be designed or modified to match specific track or guide rail geometries. This ensures proper fit, alignment, and smooth operation along the designated track, minimizing the risk of misalignment or issues related to track compatibility.
It is important to work closely with bearing manufacturers or suppliers to discuss the specific requirements of the track or linear motion application. By collaborating with experts, it is possible to customize or modify track bearings to optimize performance, reliability, and longevity in a wide range of applications.

Are there specific materials commonly used in the construction of track bearings?
Yes, specific materials are commonly used in the construction of track bearings to ensure their durability, load-carrying capacity, and resistance to various operating conditions. Let’s discuss the materials commonly used for different components of track bearings:
- Outer and Inner Rings: The outer and inner rings of track bearings are typically made from high-quality bearing steels such as chrome steel (e.g., AISI 52100) or stainless steel. These materials offer excellent strength, hardness, and wear resistance. Chrome steel is the most commonly used material due to its favorable combination of mechanical properties and cost-effectiveness. In some cases, specialized alloys or heat-treated steels may be used to enhance specific properties like corrosion resistance or high-temperature performance.
- Rolling Elements: The rolling elements in track bearings are commonly made from bearing-grade steel or ceramic materials. Bearing-grade steel, similar to the materials used for the outer and inner rings, offers high strength and wear resistance. Ceramic materials, such as silicon nitride (Si3N4) or zirconia (ZrO2), are also used in certain applications where their advantages, such as high hardness, low density, and resistance to corrosion and high temperatures, are desired.
- Cage: The cage in track bearings is typically made from materials such as steel, brass, or engineered polymers. Steel cages are commonly used due to their strength and durability. Brass cages offer good corrosion resistance and are suitable for certain operating environments. Engineered polymers, such as polyamide (nylon), are used in applications where low friction, noise reduction, or lightweight design is desired.
- Seals or Shields: The seals or shields used in track bearings are made from various materials depending on the specific requirements. Common materials include rubber or synthetic elastomers for seals, and steel or stainless steel for shields. These materials provide effective protection against contaminants while maintaining proper lubrication within the bearing assembly.
- Lubrication: Lubricants used in track bearings can vary depending on the application and operating conditions. Common lubrication options include mineral oils, synthetic oils, and greases. The lubricant’s formulation is carefully chosen to provide adequate lubrication, reduce friction and wear, and protect against corrosion and contamination.
Overall, the choice of materials for track bearings is influenced by factors such as load requirements, operating conditions (including temperature and moisture levels), desired lifespan, and cost considerations. By selecting appropriate materials for each component, track bearings can deliver reliable performance and extended service life in a wide range of industrial and mechanical applications.
