1.An improper installation, improper installation may cause damage of SKF bearings. If the high speed under the conditions of operation, and a higher operating temperature, special attention should be rotating ring with not too loose to prevent the emergence of the eccentric, and a fixed ring with non-emergence of the gap, to prevent the ring deformation under load and excitation vibration.
2.rotating rings for blanching the amount of interference to the extent possible should be made ??smaller. Ensure the impact of thermal expansion of the operating temperature, and the maximum speed the centrifugal force of the impact of creeping or sliding so as not to cause a tight fit to the surface.
Fixed ring based on the work load size and SKF bearing size, select a very small clearance fit or interference fit is too loose or too tight are not conducive to maintaining the original precise shape.
It is necessary to accurately calculate the amount of interference with the rotating rings, but also accurate calculation of the appropriate co-ordination of the fixed ring. Shaft and housing bore roundness and shoulder block verticality in accordance with the corresponding one-way bearing accuracy requirements. Guarantee by dedicated assembly mold, can ensure that the assembly precision of the bearing cage assembly of precision.
3.For heavy load situations, usually should be higher than in the light load and normal load situations with a compact. The load is heavier, its interference with should be the greater. Use pairs of duplex angular contact ball bearing spindle, most of the load is lighter, its amount of interference with such large internal axial preload will be significantly larger, resulting in adverse effects. Spindle double row cylindrical roller bearings and tapered roller bearing spindle, the load is relatively large, so with the earnings are also relatively large.
