The Timken HJ-223020.2RS is a high-performance needle roller bearing designed for applications that demand compact size, high load capacity, and effective sealing. This bearing is part of Timken’s drawn cup needle roller bearings series, which are known for their ability to manage heavy radial loads in tight spaces. The HJ-223020.2RS specifically features a full complement of needle rollers, maximizing its load-bearing potential by eliminating the need for a cage.
Size and Weight:
The HJ-223020.2RS has an inside diameter of 34.925 mm, an outside diameter of 47.625 mm, and a width of 31.75 mm. Its compact size makes it suitable for applications where space is a premium, and the bearing’s design ensures it can handle substantial loads relative to its small footprint. The precise weight of the bearing is optimized to provide strength without unnecessary mass, making it ideal for applications where weight considerations are critical.。
Performance:
This bearing is equipped with two rubber seals (indicated by “2RS”), which are positioned on both sides of the bearing. These seals effectively protect against contaminants like dust, dirt, and moisture, which enhances the bearing’s reliability and lifespan, even in challenging environments. The seals also help retain lubrication, reducing the need for frequent maintenance and ensuring smooth, efficient operation. The bearing’s full complement of needle rollers allows it to support high radial loads and maintain performance even under continuous operation at high speeds.
Usage:
The HJ-223020.2RS is commonly used in automotive transmissions, gearboxes, pumps, and other industrial machinery where compact, high-load capacity bearings are required. Its robust construction and reliable sealing make it particularly well-suited for applications involving high rotational speeds and harsh operating conditions. The drawn cup design allows for easy press-fit installation into the housing, simplifying assembly and reducing overall space requirements.
Overall, the Timken HJ-223020.2RS combines compact design, high load capacity, and superior sealing, making it a dependable choice for demanding applications across various industries.
