1.Bearing space and position of the machine

2.The size, direction and nature of the load on the bearing, the load is the most important factor in the selection of the bearing

3.Bearing alignment performance

4.The rigidity of the bearing refers to the amount of force required to produce unit deformation of the bearing.

5.Bearing movement and axial displacement

6.Convenient for bearing installation and disassembly

7.In addition to the above factors, the working environment temperature of the bearing, bearing seal and special requirements for friction torque, vibration, noise, etc. should also be considered.
