- is the load factor, the correction factor for the impact frequency of each load or the frequency of use of the equipment.

- for life factor, ball bearing 153, roller bearing 153

N- is the speed of use

L- is the life

The formula for calculating P is

Industrial applicability

According to the bearing mounting structure of the invention, the axial and radial runout can be reduced, and the smooth running of the wheel can be effectively increased. The structure of the bearing member and the bearing mounting structure of the structure is relatively simple and the manufacturing cost is low. Moreover, this structure allows the bearing to be mounted to the carrier and the bearing is angularly arranged, which can be produced according to the required axial load and radial load. The angled carrier has achieved the effect of simultaneously moving against external loads. This structure can produce any angle support as needed, and then mount the bearing on it. When the existing equipment structure is changed, the support structure can be arbitrarily replaced as long as the hole position of the support structure is left.
