TIMKEN -Torrington HJ-14017048 Needle Roller bearing,Cylindrical Roller Radial Bearings-HJ Series 222,250 X 269,875 X 76,20 (mm)

TIMKEN-Torrington HJ-14017048 Needle Roller Bearing

The TIMKEN-Torrington HJ-14017048 is a high-capacity needle roller bearing specifically engineered for heavy-duty applications that require exceptional radial load support in compact spaces. Part of TIMKEN’s extensive range of needle roller bearings, the HJ-14017048 is designed for high performance, durability, and precision, making it suitable for industrial machinery, automotive systems, and construction equipment where space constraints and load demands are critical factors.

Design and Construction

The HJ-14017048 is a full complement needle roller bearing, which means it is built without a cage, allowing it to hold the maximum number of needle rollers. This design increases the contact area between the needle rollers and the raceways, significantly enhancing the bearing’s load-bearing capacity. The bearing has an outer diameter of approximately 14 inches (355.6 mm), a length of 17 inches (431.8 mm), and a wall thickness of 4.8 inches (121.92 mm). This robust and space-efficient design allows the bearing to accommodate high radial loads effectively while fitting into confined spaces.

Constructed from high-quality, case-hardened steel, the outer ring provides excellent resistance to wear, fatigue, and impact, which ensures the bearing can withstand high-stress conditions typical in heavy-duty applications. The needle rollers are densely packed and precisely arranged to ensure even load distribution, reducing internal friction and minimizing stress concentrations. This results in smoother operation, lower operating temperatures, and extended bearing life, even in harsh operational environments. The absence of an inner ring allows the bearing to be mounted directly onto the shaft, simplifying installation and saving valuable space.

Performance Features

High Load Capacity: The full complement design of the HJ-14017048 maximizes the number of needle rollers, allowing the bearing to handle substantial radial loads effectively. This makes it ideal for applications involving continuous or shock loading, where robust load support is essential.

Compact and Efficient: The compact design of the HJ-14017048 is particularly advantageous in applications where space constraints are a major consideration. Its ability to provide high load capacity within a minimal footprint makes it a preferred choice for systems where reducing overall size is critical without compromising performance.

Durability and Longevity: The use of high-grade, case-hardened steel and a robust design contribute to the bearing’s excellent wear resistance and impact toughness. By minimizing internal friction, the bearing operates at lower temperatures, reducing wear and extending its service life even in demanding conditions.

Simplified Installation: The bearing’s design without an inner ring allows for direct shaft mounting, which simplifies the assembly process and reduces the overall size of the bearing assembly. This is particularly beneficial in applications where quick maintenance and efficient installation are important.

Applications

The HJ-14017048 is well-suited for a wide range of heavy-duty applications, including:

• Industrial Gearboxes:Its high radial load capacity and compact design make it ideal for use in gearboxes that operate under heavy stress in industrial machinery.
• Automotive Transmissions:The bearing’s robust performance and space-saving design are advantageous in automotive transmission systems, where space is limited, and reliability is critical.
• Construction Equipment:In construction machinery such as excavators, cranes, and loaders, the HJ-14017048 provides the necessary durability and load support to handle the rigorous demands of these applications.

Heavy-Duty Pumps and Conveyors: The bearing’s full complement design and high capacity make it suitable for continuous loading applications, such as in heavy-duty pumps and conveyor systems, ensuring smooth, efficient operation with minimal downtime.
