Family specifications and selection conditions
| Product description | 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. |
|---|---|
| Manufacturer features | High radial load carrying capacity • High stiffness • Low cross-sectional height • Accommodate axial displacement in both directions • Separable design |
