Bearing type is selected, the main should consider five factors:
1) aligning performance: When the two bearing bore concentricity can not guarantee or shaft deflection is large should be considered in the selection of the self-aligning roller bearings or self-aligning ball bearings.
2) stiffness requirements: usually roller bearing stiffness than ball bearings, angular contact ball bearings, tapered roller bearing preload method can further improve the stiffness of the support.
3) support limit requirements: fixed support limiting the axial displacement of the two aspects, can be selected to be able to withstand a bi-directional axial load of the bearing, the individual limit can be chosen to be able to withstand the individual axial load bearing, the motile support is not limited to bit, choice of the inner and outer ring can be separated cylindrical roller bearings.
4) load direction, size and media: radial bearings mainly bear radial load, thrust bearing by itemized load.
5) speed: the operating speed of the bearing should normally be lower than the limit speed n, deep groove ball bearings, angular contact ball bearings and roller bearing original high speed limit occasions for high-speed operation, low thrust bearing speed limit.
