1, bearing ring, related to the load related to the condition of the load direction for swing or rotating ring, should choose interference or composite bearing or transitional cooperation.Related to the load direction fixed ring should pick space cooperation.When bearing with no separation type bearing activities, should be related to the sliding bearing load direction as fixed ring as swimming ring, choose space cooperation or transition.
2, the types of load and intrusive when the impact load and heavy load, usually should pick lighter than normal, load more closely.About the centripetal bearing load of intrusive with radial equivalent dynamic load PR and radial additional dynamic negative charge to differentiate between the ratio of CR, the greater the load, the greater the cooperation interference.Load intrusive PR/CR light load is less than or equal to 0.07 normal load is greater than 0.07 ~ 0.07 heavy load is greater than 0.15.
3, bearing scale economics, with the increase of bearing scale range of the selected cooperation interference, the greater the gap, the greater the space cooperation.
4, bearing clearance using interference cooperation will cause the decrease of the bearing clearance, device shall be checked after the clearance of bearing are satisfied using the request, in order to accurately select cooperation and bearing clearance.
5, and other factors, the influence of the shaft and bearing seat, strength and thermal conductive function;Outside and in the way of thermal conductivity of heat and heat in the bearing, bearing device selection and adjustment function can affect cooperation.
