Description

About Product

The RNAF Series is the single-row type, and the RNAFW Series is the double-row type, both maintaining the same low sectional height. These bearings are designed to be used without an inner ring, utilizing the hardened and ground shaft as the raceway for a compact footprint. The radial internal clearance can be freely chosen by combining the outer ring assembly with a properly finished shaft.
