the main bearings to withstand radial loads for radial bearings. The type of bearing nominal contact angle a0 <= 45 0. Foot rain roller bearings can withstand greater radial loads than ball bearings.

N-type and NU type cylindrical roller bearings only take radial load and other types of radial bearings can bear radial load, but also can carry axial load.

2, bearing the axial load

axial load bearings are generally for the thrust bearing, its nominal contact with the corner ofa0> 450. Thrust bearing and thrust angular contact ball bearing according to the different structures can withstand the axial force of one or both directions. When the thrust cylindrical roller bearings and thrust-aligning roller bearings to withstand the force is particularly high when preferred.

Aligning thrust roller bearings and single direction thrust angular contact ball bearings can withstand axial and radial loads, the other thrust bearing can only carry axial load.

3, bearing the length of the compensation

supporting a shaft and bearing is usually a fixed bearing and swimming in the structure of the bearing assembly. Swimming bearings compensate for shaft length error and thermal expansion.

The NU and N-type cylindrical roller bearing is ideal for swimming bearings, these bearings themselves can compensate for length. The bearing inner and outer circle with a tight fit.

Slide with length compensation

Inseparable from the bearing (such as deep groove ball bearings and spherical roller bearings) also can be used for swimming bearing. This type of bearing two rings in a use with no axial mounting surface. Therefore, bearing a ring in the supporting surface activities.
