The Timken HJ-202820.2RS is a high-precision needle roller bearing designed to offer robust performance in compact applications where high load capacity and reduced friction are essential. This bearing belongs to the family of drawn cup needle roller bearings, known for their thin-walled outer rings and full complement of needle rollers that maximize load-bearing capability while minimizing overall size.

One of the standout features of the HJ-202820.2RS is its integrated rubber seals (denoted by “2RS”), which are positioned on both sides of the bearing. These seals provide effective protection against contaminants such as dust, dirt, and moisture, enhancing the bearing’s reliability and longevity, particularly in harsh operating environments. The seals also help to retain lubrication, reducing the need for frequent maintenance and ensuring smooth, quiet operation over extended periods.

The HJ-202820.2RS has an inside diameter of 31.75 mm, an outside diameter of 44.45 mm, and a width of 31.75 mm. Its compact design makes it ideal for use in applications such as automotive transmissions, pumps, compressors, and various industrial machinery where space is limited but high performance is required. The full complement of needle rollers allows the bearing to carry significant radial loads, and its precision-engineered rollers ensure minimal friction and heat generation, even at high speeds.

Constructed from high-quality steel, the HJ-202820.2RS offers excellent durability and resistance to wear, making it suitable for demanding applications. The bearing’s drawn cup design simplifies installation, allowing it to be easily press-fitted into a housing bore, which also reduces the overall assembly footprint.

Overall, the Timken HJ-202820.2RS is a versatile and durable needle roller bearing that combines high load capacity, compact design, and effective sealing to deliver reliable performance in a wide range of demanding applications.
