RN-0.5x11 BF RN-1.5x7.8 BF/G2

RN-0.5×11 BF RN-1.5×7.8 BF/G2

The RN-1.5×7.8 BF/G2 is a needle roller bearing with a compact size, featuring a 1.5mm diameter and 7.8mm length. Made from high-quality chrome steel, it offers excellent durability and hardness (HRC60-65).

This bearing is rated G2 for precision, with tight tolerances on length (0 to -0.22mm) and roundness (0.5um). Its flat ends and smooth surface ensure stable performance in tight spaces.

Suitable for high-precision applications like small gearboxes or compact machinery, it handles both axial and radial loads well. The Rsmax values of 0.6mm (axial) and 0.4mm (radial) provide flexibility in mounting.

Compliant with RoHS standards, it’s interchangeable with INA bearings, making it a practical choice for replacements. Ideal for engineers needing reliable, small-scale solutions.
