The Timken-Torrington HJ-324120.2RS is a high-performance needle roller bearing featuring dual seals, designed for applications where high radial load capacity, compact design, and contamination protection are essential. This bearing is commonly used in industries such as automotive, industrial machinery, and heavy equipment, providing reliable operation in space-constrained environments.
Size and Weight:
The HJ-324120.2RS has a bore diameter of approximately 2 inches (50.8 mm), an outer diameter of 2.625 inches (66.68 mm), and a width of 1.25 inches (31.75 mm). Its compact design enables it to handle significant loads while fitting into tight spaces, making it an ideal choice for applications where space efficiency is critical. Despite its robust capabilities, the bearing maintains a relatively lightweight profile, which helps reduce the overall weight of the machinery it supports.
Performance:
Equipped with long, slender needle rollers made from high-quality, hardened steel, the HJ-324120.2RS is capable of supporting high radial loads with minimal friction. The dual seals (2RS) provide effective protection against contaminants such as dust, dirt, and moisture, ensuring that the lubricant remains inside the bearing. This design reduces the need for frequent maintenance, enhances durability, and extends the operational lifespan of the bearing, even in challenging environments or under high-speed conditions.
Usage:
This bearing is widely used in applications that require reliable load handling and minimal maintenance, such as automotive transmissions, industrial gearboxes, and other machinery where contamination control is a priority. The sealed construction makes it particularly suitable for environments where external contaminants could otherwise degrade performance.
Structure::
The HJ-324120.2RS features a robust cage that securely positions the needle rollers, promoting stability and efficient load distribution. The dual rubber seals on both sides are designed to keep contaminants out and lubrication in, thereby reducing friction, noise, and vibration during operation. This configuration ensures smooth, quiet, and efficient performance.
Overall, the Timken-Torrington HJ-324120.2RS needle roller bearing combines high load capacity, compact size, and superior sealing, making it a dependable solution for demanding industrial applications. Its durable structure, protective seals, and ease of maintenance make it an excellent choice for ensuring long-lasting, reliable operation in various equipment and machinery.
