1, the general choice of bearing with the transition fit, that is to ensure that the bearing inner and outer ring gear pump bearings and rotating bodies, fixed body to maintain a certain degree of strength, not to slide the oil-free bushing SF-1 in sliding, at the same time, disassemble the bearing Also easy to install (press, copper hammer, wood hammer, remove with a puller)
2, axial positioning to have shoulder (or ring, spacer, etc.) to ensure that the bearing does not have axial string
3, the bearing is the existence of bearing clearance (except tapered rotor bearings, angular contact bearings), in the precision transmission, there must be a device to eliminate bearing clearance, generally can be selected between the two bearings plus inner and outer spacer method to eliminate the bearing gap
4, the bearing in operation must have good steel sleeve bearing lubrication, the best lubrication is the oil bath lubrication (that is, bubble in the oil) Of course, regular manual refueling is also possible
5. For the shaft assembly of simply supported beam structure, the bearing holes at both ends must be processed through the boring machine at one time to ensure that the holes for installing the bearing have a very high degree of coaxiality, so that the operation of the shaft will not occur. Hysteresis, while adding additional installation load

6. For a plain bearing, it is of utmost importance to produce a reasonable clearance, that is, to ensure the formation of a wedge-shaped oil film, increase the speed, and also to extend the life of the plain bearing.
