NA69/28 open Needle Roller Bearing with Inner Ring
The needle bearing NA69/28 has thin cylinders as rolling elements and can absorb very 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
-
wider than needle roller bearings of the series 49 and therefore suitable for significantly higher radial loads
-
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
