RN-0.5x6 BF RN-1x7.8 BF/G2

RN-0.5×6 BF RN-1×7.8 BF/G2

This needle roller bearing features a compact design with a 1mm diameter and 7.8mm length, made from tough chrome steel for durability. It meets G2 precision standards, ensuring smooth operation with minimal vibration.

The flat ends and high hardness (HRC60-65) make it resistant to wear, while the tight length tolerance (0 to -0.22mm) ensures a precise fit. Its roundness is finely tuned to 0.5um for consistent performance.

With low axial and radial runout (Rsmax 0.5mm and 0.3mm respectively), it’s ideal for high-precision applications. The bearing is RoHS compliant, making it safe for various industrial uses.

Perfect for compact machinery or automotive systems where space is limited but performance can’t be compromised. Interchangeable with INA bearings for easy replacement.
