Cross rollerbearing SKF

Traditional Ball bearing combination space larger than Cross roller bearing about 1.5~2times, reduce the design space and miniaturization.

The rollers designed crowning curve that to avoid stress concentrate at both ends of the roller for the reason that it is maximum stress value of the roller can be reduced and the loading is relatively average, so improve the life of cross roller bearing.

Rollers crossed at right angles between inner and outer rings , the roller and groove contact area compare with ball bearings is bigger and contributing to miniaturization and increase load capacity and rigidity.
