The Timken-Torrington HJ-364828.2RS is a high-performance needle roller bearing with dual seals, specifically designed to offer superior load capacity, compact design, and robust protection from environmental contaminants. This bearing is part of the Timken-Torrington series known for its durability and efficiency, making it a popular choice in applications such as automotive transmissions, industrial machinery, and heavy equipment where space efficiency, load handling, and protection from contaminants are essential.

Size and Weight:

The HJ-364828.2RS has a bore diameter of approximately 2.25 inches (57.15 mm), an outer diameter of 3 inches (76.2 mm), and a width of 1.5 inches (38.1 mm). The compact size of this bearing allows it to fit into tight spaces without sacrificing its load-bearing capabilities. Despite its robust load-handling capacity, the bearing maintains a relatively lightweight profile, which is advantageous in applications where reducing the overall weight of the equipment is important. This compact and lightweight nature makes the HJ-364824.2RS an ideal component for applications that require both high performance and space optimization.

Performance:

The HJ-364828.2RS is engineered to handle high radial loads with efficiency and reliability. The bearing features needle rollers made from high-quality, hardened steel, which are longer than their diameter. This design maximizes the contact surface area, allowing the bearing to support substantial loads while maintaining minimal friction and wear. The dual seals (2RS) are integral to the bearing’s performance, as they protect the internal components from contaminants such as dirt, dust, and moisture. These seals also help retain the lubricant within the bearing, ensuring consistent lubrication, reducing maintenance frequency, and extending the operational lifespan of the bearing.

The dual-seal configuration is particularly beneficial in high-speed or high-load applications, as it minimizes the risk of lubricant leakage and prevents contaminants from entering the bearing. This not only enhances the bearing’s performance but also contributes to the overall reliability and longevity of the machinery it is used in.

Usage:

The HJ-364828.2RS is suitable for a wide range of applications where space constraints, high load capacity, and protection from contaminants are critical. It is commonly used in automotive transmissions, where its compact design and load-handling capabilities are ideal for efficient power transmission. In industrial machinery, the bearing’s robust construction and sealing make it suitable for gearboxes, conveyors, and other equipment that operates under high loads and requires minimal maintenance.

In heavy equipment, such as construction and agricultural machinery, the bearing’s ability to perform reliably under heavy loads and harsh conditions makes it a preferred choice. The dual seals ensure that the bearing remains protected in environments where exposure to dust, dirt, and moisture is common, thereby reducing the risk of premature failure and downtime.

Structure：

The structure of the HJ-364828.2RS includes a robust cage that holds the needle rollers in place, ensuring stable operation 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 provide a barrier against external contaminants, while also retaining the lubricant inside. This sealed design reduces noise and vibration during operation, contributing to smoother, quieter performance.

The bearing’s design also allows for easy installation and removal, which is beneficial during maintenance or replacement. The compact and sealed structure ensures that the bearing fits well into confined spaces, making it versatile for a variety of machinery and equipment layouts.

Conclusion:

The Timken-Torrington HJ-364828.2RS needle roller bearing is a versatile, high-performance solution for applications that demand high load capacity, compact design, and reliable protection from contaminants. Its robust construction, efficient sealing, and ease of maintenance make it an excellent choice for engineers and technicians seeking dependable bearing solutions for demanding environments. Whether in automotive, industrial, or heavy equipment applications, the HJ-364824.2RS offers exceptional performance, durability, and longevity, ensuring reliable operation and reduced maintenance needs across a wide range of industrial uses.
