TIMKEN -Torrington HJ-14817848 Needle Roller bearing,Cylindrical Roller Radial Bearings-HJ Series 234,950 X 282,575 X 76,20 (mm)

TIMKEN-Torrington HJ-14817848 Needle Roller Bearing

The TIMKEN-Torrington HJ-14817848 is a high-capacity needle roller bearing engineered to support heavy radial loads in applications where space is limited. As part of TIMKEN’s renowned range of needle roller bearings, the HJ-14817848 is designed for exceptional performance, durability, and precision, making it a reliable choice for various industrial, automotive, and construction machinery applications.

Design and Construction

The HJ-14817848 is a full complement needle roller bearing, meaning it does not include a cage and instead incorporates the maximum number of needle rollers. This design maximizes the contact area between the needle rollers and the raceways, significantly enhancing the bearing’s load-bearing capacity. The bearing features an outer diameter of approximately 14.8 inches (376.3 mm), a length of 17.8 inches (451.2 mm), and a wall thickness of 4.8 inches (121.92 mm). This combination provides a robust solution for high-load applications while maintaining a compact form factor.

The outer ring of the HJ-14817848 is made from high-grade, case-hardened steel, which offers exceptional resistance to wear, impact, and fatigue. This material choice ensures that the bearing can withstand high stresses typical of demanding applications. The needle rollers are densely packed and precisely aligned to provide even load distribution, reducing internal friction and minimizing stress concentrations. This design contributes to smoother operation, lower operating temperatures, and an extended service life, even under harsh conditions. The absence of an inner ring allows the bearing to be mounted directly on the shaft, simplifying installation and conserving space.

Performance Features

High Load Capacity: The full complement design of the HJ-14817848 allows it to handle substantial radial loads effectively. By incorporating the maximum number of needle rollers, the bearing can distribute loads more evenly, making it suitable for applications involving continuous or shock loading.

Compact and Efficient: The bearing’s compact design is particularly advantageous in applications where space constraints are a significant consideration. Its ability to provide high load support within a minimal footprint makes it ideal for systems where reducing overall size is essential without compromising performance.

Durability and Longevity: The HJ-14817848’s construction from high-quality, case-hardened steel ensures it can endure wear and impact, even under heavy-duty conditions. Its optimized design reduces internal friction, leading to lower energy consumption and heat generation, which are key factors in extending the bearing’s operational life.

Simplified Installation: The absence of an inner ring enables direct shaft mounting, simplifying the assembly process and reducing the overall size of the bearing assembly. This feature is particularly useful in applications where quick maintenance and efficient installation are important.

Applications

The HJ-14817848 is suited for a variety of heavy-duty applications, including:

• Industrial Gearboxes:Its high radial load capacity and compact design make it ideal for gearboxes in industrial machinery that operate under significant stress and require reliable, long-lasting components.
• Automotive Transmissions:In automotive systems, the bearing’s robust performance and space-saving design are advantageous for transmission systems where both high performance and size constraints are critical.
• Construction Equipment:The bearing’s durability and high load capacity make it suitable for construction machinery such as cranes, excavators, and loaders, which operate in demanding environments and require dependable components.

Heavy-Duty Pumps and Conveyors: The HJ-14817848 excels in applications involving continuous loading, such as heavy-duty pumps and conveyor systems, providing smooth, efficient operation with minimal downtime.
