Product Description

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.

3. Core Advantages

Dense single-row needle roller layout delivers outstanding radial load capacity and structural rigidity for heavy-duty operation
Factory matched precision inner ring, no need for heat treatment and superfinishing on the mating shaft
Outer ring with built-in oil groove ensures uniform grease distribution and easy supplementary lubrication
Thin-wall compact design saves radial installation space for miniaturized equipment layout
Allows slight axial displacement between shaft and housing during long-time continuous running
Standard metric dimensions, fully interchangeable with same specification needle roller bearings
Custom options: double-side rubber seals, high temperature grease, OEM laser marking, P6/P5 precision grade Reduce parts abrasion, running vibration and long-term maintenance frequency of heavy equipment.

4. Application Scenarios
