R 12-2RS.C3 RICH 19,05x41,2x11,1

R 12-2RS.C3 RICH Single Row Deep Groove Ball Bearing – 19.05 x 41.2 x 11.1 mm – Sealed & Enhanced Clearance

The R 12-2RS.C3 RICH Single Row Deep Groove Ball Bearing is a high-performance component engineered to provide reliable and efficient rotational motion in a variety of applications. With precise dimensions of 19.05 mm inner diameter, 41.2 mm outer diameter, and an 11.1 mm width, this bearing is designed for systems that benefit from enhanced internal clearance. Manufactured in China by RICH, it features double-sided rubber contact seals (2RS) for superior protection against contaminants, and a C3 greater than normal internal clearance to accommodate higher speeds, thermal expansion, or misalignment. It serves as a known OE reference for HARLEY-DAVIDSON: 31539-66.

The "2RS" sealing ensures that the bearing is well-protected from dust, dirt, and moisture, while also retaining lubricant effectively, leading to extended service life and reduced maintenance. The C3 clearance is particularly beneficial in applications where operating temperatures are high or where slight misalignment might occur, preventing premature wear and ensuring smooth operation.

Weighing just 0.064 kg, this RICH deep groove ball bearing offers a practical and robust solution for optimizing performance and durability in light to moderately demanding mechanical systems, including those found in specialized applications like motorcycles.
