TIMKEN -Torrington HJ-729636 Needle Roller bearing,Cylindrical Roller Radial Bearings-HJ Series 114,300 X 152,400 X 57,15 (mm)

TIMKEN-Torrington HJ-729636 Needle Roller Bearing

The TIMKEN-Torrington HJ-729636 is a high-performance needle roller bearing designed to handle substantial radial loads in compact spaces. Part of the renowned TIMKEN brand, known for its precision and reliability, this bearing is suitable for various demanding applications in industries such as automotive, industrial machinery, and heavy equipment.

Design and Construction

The HJ-729636 is a full complement needle roller bearing, which means it does not have a cage, allowing the maximum number of needle rollers to be packed within the bearing. This design maximizes the contact surface area between the rollers and the raceways, significantly increasing the bearing’s load capacity. The bearing has an outer diameter of approximately 4.5 inches (114.3 mm), a length of 6 inches (152.4 mm), and a wall thickness of 2.25 inches (57.15 mm). This configuration makes it ideal for applications that require high radial load capacity with minimal axial space.H

The bearing’s outer ring is made from high-grade, case-hardened steel, which provides excellent wear resistance and durability under high-stress conditions. The densely packed needle rollers are arranged precisely to ensure even load distribution and minimize internal friction, which is critical for smooth operation and long service life. The absence of an inner ring allows for direct mounting on the shaft, simplifying the assembly and saving space.

Performance Features

The TIMKEN-Torrington HJ-729636 excels in high-load, low-speed applications where space efficiency and high load capacity are critical. The full complement design provides a large contact area, allowing the bearing to support heavy radial loads efficiently while maintaining stability. The robust construction reduces the risk of bearing failure due to wear, shock, or misalignment, ensuring reliable performance even under harsh operating conditions.

Applications

This bearing is commonly used in a wide range of heavy-duty applications, including automotive transmissions, gearboxes, industrial machinery, and construction equipment. Its compact size and high load-bearing capacity make it ideal for use in equipment where space is limited, but robust performance is essential. The HJ-729636 is particularly well-suited for applications involving continuous or shock loading, such as in conveyors, heavy-duty pumps, and earth-moving equipment.

Conclusion

The TIMKEN-Torrington HJ-729636 needle roller bearing is a reliable, compact solution designed for high-load applications in constrained spaces. Its full complement of needle rollers and durable construction provide exceptional load-carrying capabilities and extended service life, making it a preferred choice in demanding industrial and automotive settings. The bearing’s ability to handle substantial radial loads with minimal space requirements underscores TIMKEN’s commitment to quality and innovation in bearing technology.
