SKF bearing installation, engineers are most concerned about is how to correct operation, improper operation may cause damage of SKF bearings. If the high speed under the conditions of operation, and a higher operating t emperature, 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.
The rotating ring blanch 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.ball bearing suppliers

Shaft and housing bore roundness and shoulder block verticality in accordance with the SKF bearing the corresponding accuracy requirements.abec 7 bearings

Cage assembly accuracy to rely on a dedicated assembly mold guarantee can be fully guaranteed SKF bearing assembly precision.

Take small interference with the conditions of fixed circle is to match the surface of both sides have a high shape accuracy and smaller roughness, or cause installation difficulties demolished more difficult, in addition, also need to consider the impact of the spindle thermal elongation.

Swinging loads and uncertain load and rotation load in co-ordination should be treated equally with too loose can cause the mating surface damage.miniature bearing

Relative to the load direction of ro tation of the ring and shaft or housing bore, transition fit or interference fit. The size of the interference to the SKF bearing the work load, the ferrule does not produce the phenomenon of "creep" as the principle axis or the mating surface of the seat hole. Load is very light or heavy loads ferrule occasional low-speed rotation, the selection of the transition with the shaft surface should have a higher hardness and smaller surface roughness.

For heavy load situations, usually should be higher than in the light load and normal load situations with tight. 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.

Sometimes the direction and size of the load can not exactly determine, for example, in the high-speed rotating machinery, in addition to the load borne by the rotor weight fixed to the direction of the outer unbalance caused by the rotation of the load, if this rotation loads than the fixed load much larger, then the synthetic load is still rotating load; rotation load is much smaller than the fixed load and synthetic load to swing loads. Regardless of the load of rotating or oscillating loads, SKF bearings the size and direction are constantly changing. Variable work state, may be of some rings suffered load but rotating load, but fixed load, but also when swinging loads. This load is known as the uncertain load.
