Needle roller bearing NA6909-2RS
·High radial load carrying capacity
·High stiffness
·Low cross-sectional height
·Accommodate axial displacement in both directions
·Separable design
NA6909-2RS series needle roller bearing. It's double row needle roller bearing.
Double row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length.
Owing to large quantity of rollers, the bearings have a high load-carrying capacity.
The outer ring includes flanges to guide the roller and cage units and has features to facilitate relubrication.
It is possible to separate the inner and outer rings, permitting interference fits for shaft and housing and enabling easy maintenance inspections.
