RN-0.5x31 BF RN-2x11.8 BF/G2

RN-0.5×31 BF RN-2×11.8 BF/G2

The RN-2×11.8 BF/G2 is a needle roller bearing with a 2mm diameter and 11.8mm length, crafted from hard-wearing chrome steel. Its flat ends and precise roundness of 0.5µm ensure smooth operation in tight spaces.

This bearing meets G2 rating standards, offering reliable performance with minimal radial and axial runout (0.6mm and 0.8mm max respectively). It’s interchangeable with INA models, simplifying replacements.

Ideal for compact assemblies like gear pumps or small engines, where space is limited but durability is key. RoHS compliant for safe use in various industries.

The hardness of HRC60-65 and tight length tolerance (0 to -0.27mm) make it a robust choice for high-precision applications. Its small size belies its strength.
