TIMKEN -Torrington HJ-729640 Needle Roller bearing,Cylindrical Roller Radial Bearings-HJ Series 114,300 X 152,400 X 63,50 (mm)

TIMKEN-Torrington HJ-7296340 Needle Roller Bearing

The TIMKEN-Torrington HJ-7296340 is a high-capacity needle roller bearing specifically designed for applications where space constraints and high radial load capacity are critical. As part of TIMKEN’s extensive range of needle roller bearings, the HJ-7296340 is built to deliver durability, precision, and reliability across a variety of demanding industrial and automotive applications.

Design and Construction

The HJ-7296340 is a full complement needle roller bearing, which means it includes the maximum possible number of needle rollers without a cage. This design maximizes the load-bearing surface area, allowing the bearing to support heavy radial loads efficiently. The bearing measures approximately 4.25 inches (108 mm) in outer diameter, 7 inches (177.8 mm) in length, and 2.25 inches (57.15 mm) in wall thickness, offering a robust yet compact solution for high-load applications.The outer ring is made from high-quality, case-hardened steel, providing excellent resistance to wear, fatigue, and impact under heavy loading conditions. The needle rollers are meticulously arranged to ensure uniform load distribution, minimizing stress and reducing the likelihood of premature bearing failure. The absence of an inner ring allows the bearing to be mounted directly on the shaft, which not only saves space but also enhances flexibility in various assembly configurations.

Performance Features

The full complement of needle rollers within the HJ-7296340 allows it to handle substantial radial loads, making it suitable for applications involving continuous or fluctuating stresses. The bearing’s design minimizes internal friction, resulting in lower operating temperatures and improved energy efficiency. This robust construction provides excellent stability and ensures the bearing can withstand harsh operating environments, such as those found in industrial and heavy machinery applications.

Applications

The TIMKEN-Torrington HJ-7296340 is widely used in sectors such as automotive, construction, and industrial machinery. Common applications include automotive transmissions, gearboxes, conveyors, and heavy-duty pumps, where the bearing’s compact size and high load capacity offer significant advantages. Its ability to handle severe radial loads with limited space requirements makes it an ideal choice for equipment that must perform reliably under demanding conditions.

Conclusion

The TIMKEN-Torrington HJ-7296340 needle roller bearing is a robust, high-capacity solution designed for heavy-duty applications in compact spaces. Its full complement of needle rollers ensures maximum load support, while its durable construction provides long-lasting performance and reliability. This bearing exemplifies TIMKEN’s commitment to delivering high-quality, innovative bearing solutions tailored to meet the stringent demands of industrial and automotive environments.
