Product Description

Product Description

Cam Follower Stud Type Track Rollers Needle Roller Bearing
(bolt bearings, cam bearings, curve roller needle
bearings, roller bearings, roller needle bearings) are mainly
bearing units composed of a bolt shaft, thick-walled outer ring
and other bearing components. The thick-walled outer ring of the
curve roller can withstand impact loads and reduce deformation and
bending stress. The outer working surface of the thick-walled
outer ring is designed with a circular arc, mainly to avoid stress
concentration, but it can provide a curved roller with a
cylindrical (straight line) working surface for specific
applications. The bolt shaft can be equipped with a hexagonal nut
to quickly and easily install the bearing to the corresponding
machine part. Curved rollers are mainly suitable for track
transmission and other mechanical equipment.

Manufacturers can provide bearings with varying sizes and load capacities to accommodate different application requirements.
  • 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.

track bearing

Can track bearings be used in both light-duty and heavy-duty machinery applications?

Yes, track bearings can be used in both light-duty and heavy-duty machinery applications. They are versatile components that offer reliable support for linear motion in a wide range of industrial settings. Here’s a detailed explanation:

1. Light-Duty Machinery Applications:

In light-duty machinery applications, track bearings provide cost-effective and efficient solutions for various tasks. Light-duty track bearings are designed to handle lower loads and are commonly used in applications such as:

  • Office automation equipment
  • Consumer electronics
  • Printing machinery
  • Small conveyors and material handling systems
  • Automated vending machines
  • Textile machinery

These applications typically involve lighter loads and lower operating speeds, making light-duty track bearings suitable for providing smooth and reliable linear motion.

2. Heavy-Duty Machinery Applications:

Track bearings are also widely used in heavy-duty machinery applications that require robust components capable of handling substantial loads and challenging operating conditions. Heavy-duty track bearings are designed to withstand higher loads and offer increased durability. They are commonly employed in applications such as:

  • Material handling equipment
  • Construction machinery
  • Mining equipment
  • Transportation systems
  • Industrial automation
  • Large-scale conveyors
  • Steel mills

These applications often involve heavy loads, high operating speeds, and demanding environments. Track bearings in heavy-duty machinery applications are engineered to provide reliable performance, extended service life, and resistance to factors such as contamination, shock, and vibration.

Track bearings are available in various sizes, designs, and load capacities, allowing them to be tailored to the specific requirements of both light-duty and heavy-duty machinery applications. Manufacturers offer a range of options to accommodate different load capacities, operating conditions, and performance specifications.

It is important to consider the specific requirements and operating conditions of the machinery application when selecting track bearings. Consulting with bearing manufacturers or industry experts can help ensure the appropriate track bearings are chosen for optimal performance and reliability in both light-duty and heavy-duty machinery applications.

track bearing

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.
