HJ 202820 RICH 31,75x44,45x31,75

HJ 202820 RICH Needle Roller Bearing Without Inner Ring - 31.75 x 44.45 x 31.75 mm

The HJ 202820 RICH is a high-quality needle roller bearing without an inner ring, meticulously manufactured by RICH in China. This bearing is specifically designed for applications where the shaft itself can serve as the raceway, offering a compact and highly efficient solution for maximizing radial load capacity within limited space.

With precise dimensions of 31.75 mm bore, 44.45 mm outer diameter, and 31.75 mm width, it provides a robust and effective solution for various industrial and automotive applications. This RICH bearing features a durable steel cage, ensuring robust performance and reliable guidance of the needle rollers, even under high-speed and heavy-load conditions. The "2RS" suffix, though not explicitly listed in the model name but implied by the "double-sided rubber, contact" sealing, indicates that this bearing is equipped with double-sided rubber contact seals, offering excellent protection against contaminants like dust and moisture while effectively retaining lubricant, ensuring extended service life and reduced maintenance.

Weighing 0.138 kg, this lightweight yet durable component from RICH offers dependable performance and resilience. It is ideally suited for automotive transmissions, universal joints, power tools, and other machinery where high radial loads need to be accommodated in a confined space, and where the shaft can be hardened and ground to serve as the inner raceway.
