TIMKEN -Torrington HJ-10412848 Needle Roller bearing,Cylindrical Roller Radial Bearings-HJ Series 165,100 X 203,200 X 76,20 (mm)

TIMKEN-Torrington HJ-10412848 Needle Roller Bearing

The TIMKEN-Torrington HJ-10412848 is a full complement needle roller bearing designed to provide exceptional radial load capacity in compact spaces, making it ideal for demanding industrial, automotive, and heavy machinery applications. As part of TIMKEN’s extensive range of needle roller bearings, the HJ-10412848 is engineered for high performance, durability, and precision, offering reliable operation in environments where heavy loads and limited space are key considerations.

Design and Construction

The HJ-10412848 is characterized by its full complement design, which means it does not include a cage and instead holds the maximum number of needle rollers. This arrangement significantly boosts the bearing’s load-carrying capacity by maximizing the contact area between the needle rollers and the raceways. The bearing features an outer diameter of approximately 10 inches (254 mm), a length of 12 inches (304.8 mm), and a wall thickness of 4.8 inches (121.92 mm). This design provides a robust, space-efficient solution for applications where maintaining a high load capacity within limited dimensions is critical.

The outer ring of the HJ-10412848 is manufactured from high-quality, case-hardened steel, which provides excellent resistance to wear, fatigue, and impact, ensuring durability under high-stress conditions. The needle rollers are meticulously arranged to ensure uniform load distribution, which reduces internal friction and minimizes stress concentrations. This contributes to smoother operation and lowers operating temperatures, extending the bearing’s service life even in harsh environments. The absence of an inner ring allows for direct mounting on the shaft, simplifying the assembly process and conserving space.。

Performance Features

High Load Capacity: The full complement of needle rollers allows the HJ-10412848 to support substantial radial loads, making it ideal for applications involving continuous or shock loading. The absence of a cage increases the number of rollers, enhancing the bearing’s ability to handle high radial forces efficiently.

Compact Design: The bearing’s compact design is particularly advantageous in applications where space is at a premium but high performance is required. This makes it a preferred choice for applications where traditional roller bearings might be too large or where minimizing overall system size is a priority.

Durability and Reliability: Constructed from high-grade materials, the HJ-10412848 offers excellent resistance to wear and impact. Its design minimizes internal friction, resulting in reduced heat generation and energy consumption, which are critical for long-term reliability and efficiency.

Simplified Installation: The absence of an inner ring allows for direct shaft mounting, which simplifies installation and reduces the overall footprint of the bearing assembly. This feature is particularly useful in applications where ease of maintenance and assembly speed are important considerations.

Applications

The HJ-10412848 is well-suited for a variety of heavy-duty applications, including:

Automotive Transmissions: Its high load capacity and compact form make it ideal for use in transmission systems where space is limited, and high reliability is essential.

• Industrial Gearboxes:The bearing’s ability to handle substantial radial loads makes it suitable for gearboxes that operate under high stress and require robust, dependable components.
• Construction Equipment:In heavy machinery like excavators, loaders, and cranes, the HJ-10412848 provides the necessary load support while conserving valuable space within the machinery.

Heavy-Duty Pumps and Conveyors: The bearing’s design allows it to handle the continuous loading and unloading stresses typical in pumps and conveyor systems, ensuring smooth and efficient operation.
