RN-0.5x169 BF RN-3X7.8 BF/G2

RN-0.5×169 BF RN-3X7.8 BF/G2

The RN-3X7.8 BF/G2 is a needle roller bearing with a 3mm diameter and 7.8mm length, made from hard-wearing chrome steel. It meets G2 precision standards, ensuring smooth operation in tight spaces.

With flat ends and high hardness (HRC60-65), it handles radial loads well while maintaining low friction. The roundness of just 0.5um reduces vibration for quieter performance.

Its compact design suits applications where space is limited, such as gear pumps or small engines. The bearing is interchangeable with INA models, offering flexibility for replacements.

Compliant with RoHS standards, it’s a reliable choice for industrial or automotive use. The precise tolerances (0 to -0.22mm length) ensure consistent fit and performance.
