How to accurately select SKF FAG INA TIMKEN NSK NMB NTN KOYO NACHI Bearings

How to accurately select SKF bearings is crucial, demand from many aspects to consider its function and performance.

At present, in the industrial use of rolling bearings various mechanical equipment. Equipment and other shopping malls increasingly stringent and rapid growth in demand, the requirements for imported bearings are also increasingly diverse functions and conditions. SKF bearings bearing equipment has a bearing on the rigidity of the impact, in general, in order to choose from a large number of structures and scales the most suitable for our bearings, which requires all the performance from the bearing.

The first depends on the bearing structure is set as a shaft bearing system, the device, the ease of disassemble, the scale and the bearing of the mall, the bearings allow the space, so the selection of imported bearings, to think about the above Elements. Second, while comparing the use of bearings in various mechanical planning life and bearing a variety of different durability limits, while bearing the resolution of the resolution. In the selection of bearings, usually partial to only think about the bearing fatigue life, the grease aging occurs due to grease life, wear, noise, etc. also need plenty of research. Furthermore, depending on the application, it is necessary to select bearings for precision, clearance, cage construction, greases, etc. for special planning. Second, the selection of bearings and there is no necessary order, rules, priority should be considered on the bearing the requested conditions, performance, the most immediate matters, and for the actual.

For centripetal thrust ball bearings and roller bearings, pairs of applications should be adopted when the outer surface of the large end of the relative (IE pressure line pressure cone tip outward) equipment, so equipped with anti-overturning torque bearing capacity Large, the amount of pr-tweaking it changes less frequently as the temperature changes.

Each SKF bearings are for one-way axial positioning, and the opposite direction. This combination is mainly used for short shafts. All radial bearings that can accept at least one direction of axial load are applicable, including deep groove ball bearings and angular contact ball bearings, tapered roller bearings and NJ cylindrical roller bearings, angular contact ball bearings or tapered roller bearings, in some cases it is necessary to apply a preload.

As long as the stamping outer ring needle roller bearings, its outer wall is very thin, the best cannot use hand hammer hit the device approach, it is because the hand hammer hit, the bearing pressure uneven, simple needle roller Local deformation of the bearing outer ring. The device should be pressed using a press.

The above information is introduced how to accurately select the imported bearings
