1.Choice and control of a shaft and the bearing chamber tolerances
   

SKF bearings pressed into the bearing rotating flexible block sense. If the apparent rotation is not flexible, that the axis size is too large, the tolerance to be lowered. Such as SKF bearings pressed into the shaft is turned by hand "imperfections" in a sense, it may be the axis of the tolerance is too large or shaft roundness is not good. So also in the control of a good shaft and bearing room tolerance control roundness, many domestic manufacturers only on the tolerance control, no control of roundness.

2, the SKF bearing assembly ways
   

SKF bearings are precision products, such as improper assembly can easily damage the SKF bearing channel, resulting in the damage of SKF bearings. Bearings in the assembly should have a special mold, can not be beat, can only be pressed into the shaft, a small circle, force, pressure of the great circle only great circle force. Require the use of pneumatic or hydraulic assembly, press-fit upper and lower mold outside the state level, if inclined to cause damage to the bearing channel due to the force, leaving SKF bearings to produce the guide ring.

3, the assembly of foreign bodies to prevent
   

SKF bearings mounted to the rotor on balancing very easy to generate dynamic balance when iron filings into the bearing, so it is best to do balancing mounted bearings. Some manufacturers in order to facilitate the assembly, the assembly in the SKF bearing indoor coated with oil or grease lubrication effect, but often the operator is difficult to control, if the oil or grease in the bearing indoor accumulates more in the bearing rotation very easily along the shaft into the bearing. SKF bearing chamber is preferably not coated with oil or grease, such as non-coated not have to control shall accumulates in the SKF bearing indoor.
