TIMKEN-Torrington HJ-9211648 Needle Roller Bearing
The TIMKEN-Torrington HJ-9211648 is a high-capacity needle roller bearing designed for applications requiring exceptional radial load support in compact spaces. This bearing is part of TIMKEN’s well-regarded line of needle roller bearings, which are known for their durability, precision, and ability to perform reliably under heavy-duty conditions. It is particularly suited for demanding industrial, automotive, and construction machinery applications.
Design and Construction
The HJ-9211648 is a full complement needle roller bearing, meaning it is constructed without a cage, allowing the maximum number of needle rollers to fit within the bearing. This design maximizes the load-bearing capacity by increasing the contact surface area between the needle rollers and the raceways. The bearing has an outer diameter of approximately 7 inches (177.8 mm), a length of 11 inches (279.4 mm), and a wall thickness of 2.5 inches (63.5 mm), offering a robust yet compact solution for applications where space constraints and high load demands intersect.
Crafted from high-quality, case-hardened steel, the outer ring of the HJ-9211648 provides excellent wear resistance and toughness, ensuring the bearing can withstand high stress and impact. The densely packed needle rollers are precisely aligned to ensure even load distribution, which reduces internal friction and minimizes wear. The absence of an inner ring allows the bearing to be mounted directly on the shaft, simplifying installation and conserving space.。
Performance Features
The full complement design of the HJ-9211648 allows it to handle substantial radial loads efficiently, making it ideal for applications that experience continuous or shock loading. Its design minimizes internal friction, resulting in lower operating temperatures and enhanced energy efficiency. This not only contributes to smoother operation but also extends the service life of the bearing, even in harsh and demanding environments.
Applications
The HJ-9211648 is commonly used in heavy-duty applications such as automotive transmissions, industrial gearboxes, heavy machinery, and construction equipment. Its compact size and high load capacity make it ideal for equipment where space is at a premium but robust performance is essential, such as in conveyors, heavy-duty pumps, and earth-moving machinery.
Conclusion
The TIMKEN-Torrington HJ-9211648 needle roller bearing is a high-capacity, compact bearing solution designed for demanding applications that require exceptional radial load support. Its full complement design and robust construction provide superior performance, making it a preferred choice in industrial and automotive environments where reliability and efficiency are crucial. This bearing exemplifies TIMKEN’s commitment to delivering high-quality, innovative bearing solutions tailored to the needs of modern machinery and equipment.
