Design considerations
- Shaft and housing tolerances
Double 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. NR supplies needle roller bearings in many different designs, series and in a wide range of sizes, which make them appropriate for a wide variety of operating conditions and applications.
- High radial load carrying capacity
- High stiffness
- Low cross-sectional height
