TIMKEN-Torrington HJ-13216248 Needle Roller Bearing

The TIMKEN-Torrington HJ-13216248 is a full complement needle roller bearing engineered for heavy-duty applications that require high radial load capacity in compact spaces. This bearing is part of TIMKEN’s robust lineup of needle roller bearings known for their durability, reliability, and precision. Designed to excel in demanding environments, the HJ-13216248 is ideal for industrial machinery, automotive systems, and construction equipment where performance and space efficiency are critical.

Design and Construction

The HJ-13216248 is a full complement needle roller bearing, which means it is constructed without a cage, allowing for the maximum number of needle rollers. This design significantly increases the contact area between the needle rollers and the raceways, maximizing the bearing’s load-bearing capacity. The bearing has an outer diameter of approximately 13 inches (330.2 mm), a length of 16.2 inches (411.48 mm), and a wall thickness of 4.8 inches (121.92 mm), making it a robust yet space-efficient solution for high-load applications.

The outer ring is crafted from high-quality, case-hardened steel, offering exceptional resistance to wear, impact, and fatigue. This material choice ensures the bearing can endure the high stresses typical in heavy-duty operations. The densely packed needle rollers are precisely aligned to provide even load distribution, which reduces internal friction and stress concentrations. This design not only contributes to smoother operation but also helps in maintaining lower operating temperatures, enhancing the bearing’s overall lifespan. The absence of an inner ring allows the bearing to be mounted directly on the shaft, simplifying the installation process and conserving valuable space.

Performance Features

High Load Capacity: The full complement design of the HJ-13216248 maximizes load-bearing capacity by incorporating the maximum number of needle rollers. This enables the bearing to handle substantial radial loads effectively, making it suitable for continuous or shock loading applications where high capacity is required.

Compact Design: The HJ-13216248’s compact form factor is particularly advantageous in applications where space is at a premium. Its ability to provide high load support in a small footprint makes it an excellent choice for systems where overall size must be minimized without compromising performance.

Durability and Longevity: The bearing’s high-quality, case-hardened steel construction ensures it can withstand wear and impact, even under heavy loads. The optimized design minimizes internal friction, which reduces energy consumption and heat generation, key factors in extending the operational life of the bearing.

Ease of Installation: The absence of an inner ring allows for direct shaft mounting, simplifying assembly and reducing the overall dimensions of the bearing system. This feature is especially beneficial in applications where efficient maintenance and quick installation are important.

Applications

The HJ-13216248 is well-suited for a variety of heavy-duty applications, including:HJ

• Industrial Gearboxes:Its high radial load capacity and compact design make it ideal for gearboxes in industrial machinery that require reliable, long-lasting components under heavy operational stress.
• Automotive Transmissions:In automotive systems, the HJ-13216248’s ability to handle high loads while conserving space is crucial in transmission systems where both performance and size constraints are critical.
• Construction Equipment:The bearing’s robust construction and high performance make it suitable for construction machinery such as cranes, excavators, and loaders, which operate in challenging environments and require durable, reliable components.

Heavy-Duty Pumps and Conveyors: The HJ-13216248 is well-suited for continuous loading applications, such as heavy-duty pumps and conveyors, where it provides smooth and efficient operation with minimal downtime.

 

Conclusion

The TIMKEN-Torrington HJ-13216248 needle roller bearing is a high-capacity, durable solution designed for demanding applications that require exceptional radial load support in compact spaces. Its full complement design enhances load-bearing capacity, while the high-quality construction ensures reliable performance under heavy loads. This bearing reflects TIMKEN’s dedication to providing innovative and robust bearing solutions that meet the rigorous demands of modern industrial and automotive environments. Whether deployed in heavy machinery, automotive systems, or industrial equipment, the HJ-13216248 delivers the durability, efficiency, and performance needed to keep operations running smoothly and effectively.
