Needle roller bearing with inner ring
The ZIBOO NA4920 is a needle roller bearing supplied with an inner ring for shaft sizes that lack a hardened raceway. It suits maintenance engineers and machine rebuilders who need a compact radial bearing for moderate-speed applications. The unit arrives new in a single box from INA.
Fits shafts needing a supplied inner ring
This bearing serves technicians who cannot harden or grind the shaft to serve as the raceway. It is not for designs where the shaft itself is prepared as a raceway, for axial-load-dominant arrangements, or for assemblies that require a sealed or shielded variant.
100x140x40 mm envelope
The bearing occupies a 100 mm bore, 140 mm outside diameter and 40 mm width envelope. That exact boundary decides whether the NA4920 will seat in the housing and clear adjacent components.
