NA4904 open Needle Roller Bearing with Inner Ring
The needle bearing NA4904 has thin cylinders as rolling elements and can absorb high radial forces with its massive bearing rings. It is suitable for space-saving installation.
Features
-
it consists of a machined massive outer ring with rib, a needle roller and cage assembly and a separable inner ring
-
suitable for high radial load capacities
-
seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
-
can be used if the surface of the shaft is not suitable as a raceway
