How to accurately select SKF import bearing is crucial, need to think about its function and performance from many aspects.

The SKF import bearing equipment has a critical impact on the rigidity of the bearing, generally speaking, in order to be able to select from a large number of structures and scales suitable for our bearings, which requires the study of each performance from the bearing. This requires a study of the individual properties of the bearing.

The first depends on the bearing structure is as a shaft system bearing placement, installation, disassembly of the difficulty, scale and bearing of the mall, bearing space promised, so the selection of imported bearings, to consider the above elements. Secondly, while comparing and studying the planning life of various machinery using the bearings and the various different durability limits of the bearings, while deciding the bearing scale. In the selection of bearings, usually biased only think about the bearing fatigue life, about the grease aging by the grease life, wear, noise, etc. also need to study adequately. In addition, according to the different use, it is necessary to select the precision, clearance, cage structure, grease and so on request, make special planning of the bearing. Secondly, the selection of bearings is not necessarily in order, rules, priority should be given to the conditions requested by the bearing, performance, there are direct matters, and for the actual.

For the centripetal thrust type ball bearings and roller bearings, in pairs should be adopted when the outer ring large end face relative (that is, its pressure line constituted by the pressure cone tip outward) of the equipment, so that the equipment bearing resistance to overturn the torque of the ability to large, in the temperature change when its tuned preload amount also less change.

Each SKF import bearing to the shaft for a one-way positioning, and the opposite direction. This combination is mainly used for short shaft. All less can accept a direction of axial load radial bearings are applicable, including deep groove ball bearings and angular touch ball bearings, tapered roller bearings and NJ type cylindrical roller bearings, the use of angular touch ball bearings or tapered roller bearings, in some occasions, it is necessary to apply preload.

For as long as the stamping outer ring of needle roller bearings, its outer ring wall is very thin, good can not use hand hammering device method, this is because the hand hammering, bearing pressure is not uniform, simple make needle roller bearing outer ring produce local deformation. The device should be pressed in using a press.
