NA6911 open Needle Roller Bearing with Inner Ring
The needle bearing NA6911 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
