Descrição do produto
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.

8. FAQ
Q1: What does NA stand for?
NA series needle roller bearing is equipped with matched inner ring; RNA series without inner ring.
Q2: Full dimension and separate inner ring model?
110×140×30mm; independent inner ring: IR110×120×30.
Q3: Difference between NA and RNA needle bearings?
NA with inner ring can be installed on common shafts directly; RNA requires hardened and ground shaft surface as rolling raceway.
