TIMKEN -Torrington HJ-405228.2RS with seals, Needle Roller bearing,Cylindrical Roller Radial Bearings-HJ-2RS Series 63,500 X 82,550 X 44,45 (mm)

The Timken-Torrington HJ-405228.2RS is a high-performance needle roller bearing featuring dual seals, designed for demanding applications that require exceptional load capacity, compactness, and enhanced protection from environmental contaminants. This bearing is part of Timken-Torrington’s extensive line of needle roller bearings, known for their robustness and reliability in various industrial settings, including automotive, industrial machinery, and heavy equipment.

Size and Weight:

The HJ-405228.2RS has a bore diameter of approximately 2.5 inches (63.5 mm), an outer diameter of 3.25 inches (82.55 mm), and a width of 1.75 inches (44.45 mm). This compact design allows it to fit into tight spaces without sacrificing its ability to handle high radial loads. The bearing’s relatively lightweight construction, typical of needle roller bearings, makes it advantageous in applications where minimizing the overall weight of the machinery is important. This compact and efficient design makes the HJ-405228.2RS an ideal choice for use in equipment where space optimization and load handling are critical considerations.

Performance:

The HJ-405228.2RS is designed to deliver excellent performance in terms of load capacity, durability, and operational efficiency. The bearing utilizes needle rollers that are longer than their diameter, providing a larger surface area for load distribution. These needle rollers are crafted from high-grade, hardened steel, which offers superior strength, wear resistance, and longevity. The bearing’s construction allows it to handle substantial radial loads with minimal friction, making it suitable for high-speed and high-load applications.

A key feature of the HJ-405228.2RS is its dual-seal configuration (2RS), which provides a high level of protection against contaminants such as dust, dirt, and moisture. These seals help maintain the internal lubrication, ensuring consistent performance and reducing the need for frequent maintenance. By keeping contaminants out and lubrication in, the seals contribute significantly to extending the bearing’s operational life, especially in harsh or challenging environments.

The bearing’s precise manufacturing tolerances ensure smooth operation with reduced noise and vibration. This characteristic is particularly valuable in applications that require quiet and efficient operation, such as automotive transmissions and precision industrial gearboxes.

Usage:

The HJ-405228.2RS is versatile and well-suited for a broad range of applications across different industries. In automotive applications, it is commonly used in transmissions and drivetrains, where its compact size and high load capacity are beneficial. The bearing’s sealed design makes it ideal for environments where exposure to contaminants could compromise performance, ensuring reliable operation over long periods with minimal maintenance.

In industrial settings, the HJ-405228.2RS is used in gearboxes, conveyor systems, and other machinery that operates under high loads and requires reliable, low-maintenance bearings. Its ability to withstand heavy loads and protect against contaminants makes it an excellent choice for industrial equipment that operates in challenging conditions, such as in manufacturing plants, construction equipment, and agricultural machinery.

Structure:

The structure of the HJ-405228.2RS includes a cage that holds the needle rollers securely in place, promoting stability and efficient load distribution. The needle rollers are precisely aligned within the cage to minimize friction and ensure smooth operation. The dual rubber seals on both sides of the bearing are designed to keep contaminants out while retaining lubricant inside, which is critical for reducing wear and extending the bearing’s service life.。

The sealed structure not only protects the internal components but also reduces noise and vibration during operation, enhancing the overall efficiency of the machinery. The bearing’s design allows for easy installation and maintenance, with its compact dimensions making it suitable for tight spaces where traditional bearings might not fit.

Conclusion:

Overall, the Timken-Torrington HJ-405228.2RS needle roller bearing offers an exceptional combination of high load capacity, compact size, and superior sealing. Its durable construction, efficient performance, and reliable sealing make it a preferred choice for demanding applications in automotive, industrial, and heavy equipment sectors. Whether in transmissions, gearboxes, or other machinery, the HJ-405228.2RS provides the robust performance, longevity, and low maintenance required to keep equipment running smoothly and efficiently.
