all sizes import japanese brand NA NA69 series NA6911 needle roller bearing RNA6911 size 55x80x45mm

 

Needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.

 

BHR 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.

1. Needle roller and cage assembly

2. Drawn cup needle roller bearings

3. Needle roller bearings with machine rings

4. Alignment needle roller bearings

5. Universal joint bearings

6. Combined needle roller bearings

7. Needle roller thrust bearings

8. Cam follower, track rollers
