Selection of bearings, should be based on actual working conditions, first determine the type of bearing, and then computing was chosen bearing data, audit the performance of the selected bearing, select the bearing lubricant and lubrication method to determine the co-ordination of bearings and related components, fasteningpreload, installation and removal of the way. The specific choice of elements is as follows:
1, the rolling bearing selection

(1) Rolling outside uninstall the determination of charge.
(2) Bearing type selection.

(3) rolling bearing material of choice.
(4) bearing clearance selection.
(5) the choice of the rolling bearing tolerance grade.
2, the rolling bearing selection and calculation
(1) the calculation of reliability of rolling bearings.
(2) the calculation of the fatigue life of rolling bearings.
(3) Rolling equivalent dynamic load calculation.
(4) the calculation of rolling bearing friction torque.
3, the performance audit of the rolling bearing
(1) Rolling audit of the static strength.
(2) the audit of the rolling bearing limiting speed.
(3) Rolling swing angle of the audit.
(4) Rolling aligning performance audit.
4, the rolling bearing lubrication selection
(1) the choice of the rolling bearing lubrication methods.
(2) the choice of the rolling bearing lubricants.
(3) of the rolling bearing lubricant usage.
(4) determine the replacement cycle of rolling bearing lubricants.
5, the rolling bearing application design
Rolling with the determination of (1).
(2) axis and the bearing hole tolerances OK.
(3) Rolling axial fastening and preload design.
(4) bearing the seal choice.
(5) bearing installation and removal.
