제품 설명
1. Product Overview

NA4822 is single row machined needle roller bearing equipped with matched separable inner ring, consisting of outer ring, needle rollers and stamped steel cage as integrated assembly. Slim radial section brings great load capacity and high rigidity. The supporting inner ring avoids extra quenching and grinding processing on mating shafts, simplifying assembly design, suitable for heavy radial load machinery with limited mounting space.

Formal quotation will be sent within 24 hours upon your inquiry.
