NA 4928 Bearing Inner Races Needle Roller Bearing 140 X 190 X 50mm NA4928 Weight 4.15 Kgs
Single row needle roller bearing with machined rings, with flanges
Single row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication.
- High radial load carrying capacity
- High stiffness
- Low cross-sectional height
- Accommodate axial displacement in both directions
- Separable design
