传动轴上轴承主要承受径向力，球轴承作为轴承的主体部分，在承受载荷方面，

Bearings on the transmission shaft mainly bear radial forces. As the main part of the bearing, ball bearings mainly bear axial loads. In some cases, they will bear partial radial loads, but tapered roller bearings can withstand larger loads. Radial load, which can ensure the normal operation of the turntable. According to the minimum shaft diameter, 30203 tapered roller bearings are used, and 51128 thrust ball bearings are selected according to the size of the turntable.

The bearings on the transmission shaft mainly bear radial force, ball bearing as the main part of the bearing, in terms of bearing the load, mainly bear axial load, some conditions will bear part of the radial load, but the cone roller bearing can withstand a larger radial load, so as to ensure the normal operation of the turntable. According to the minimum shaft diameter selection 30203 type conical roller bearings, through the size of the turntable to choose 51128 thrust ball bearings.
