1, bearing radial load

To the heart bearings is refers to the main bear radial load bearing. This type of bearing nominal contact Angle a0 < = 450. For the same size of the roller bearing than ball bearings can withstand the radial direction load more.

N type and NU type fuel outlet cylindrical roller bearing is only bear radial load, and other types of to heart bearings is can bear radial load, also can carry axial load.

2, bearing axial load

Thrust bearing is refers to the main axial load bearing, its nominal contact corner a0 > 450. Thrust bearing and thrust Angle contact ball bearing according to different structure and can take one or two of the direction of axial force. When the force under special high optimization with cylindrical roller thrust bearing and thrust self-aligning roller bearings.

Thrust self-aligning roller bearings and i.e.one-way thrust Angle contact ball bearing can also carry axial load and radial load, other thrust bearing can only carry axial load.

3, bearing the length of their compensation

Usually, the fixed bearing and the structure of bearing combination swimming to supporting a shaft and bearing. Walk the length of the shaft bearing compensation error and thermal expansion. NU type fuel outlet and N type cylindrical roller bearing is ideal for swimming bearing, the bearing can compensate for their length. Bearing with important internal and external circle

4, the length of the sliding with compensation

Swimming is to point to not be separated bearing (such as deep groove ball bearings and spherical roller bearing). This type of bearing two rings of a using cooperate, no axial fixed surface. So, bearing a contractor in the bearing surface can it activities.

5 ,separable bearing (precision)

But bearings is one that can separate installation bearings. When the two front-runners are used when a tight fit its advantage is very outstanding. And bearings can include four-point contact ball bearing, double ring in half a double row angular contact ball bearing, cylindrical roller bearing, tapered roller bearings, thrust ball bearings, thrust cylindrical roller bearing and thrust self-aligning roller bearings. In addition, not bearings are: deep groove ball bearings, a single Angle contact ball bearing, self-aligning ball bearings, peng form roller bearings and spherical roller bearing.
