Improper installation, improper installation is likely to cause INA bearing damage. As in the premise operation, and the work of higher temperature, special attention should be with rotating contractor must not be too loose, to prevent a eccentric vibration, and fixed the collar with not a gap, to prevent the front-runners in load stimulate and deformation vibration.

Rotating contractor over surplus quantity of burning in possible range has also advised small. As long as really ensure the operating temperature influence of thermal expansion, and under the influence of the highest speed centrifugal force, not only caused a tight fit motion of the surface or sliding. Fixed according to the work load size and collar spindle bearing size, the selection of the tiny clearance fit or with interference, too loose or too tight, has not kept the original accurate appearance. Both precise rotation of the rings with surplus quantity, but also to the accurate calculation of the collar with appropriate amount fixed. Axis and a hole and block the roundness shoulder vertical degree according to the corresponding precision requirements to bearing. Maintains a assembly precision die by special assembly that can guarantee the INA bearing assembly accuracy.

For heavy load occasions, usually in light load and should be better than the normal load with the occasion for tight. The heavy load, the interference with the larger should be. Use spindle bearing spindle in pairs, most load is lighter, with its over surplus quantity such as too large, the internal axial preloaded volume will obviously too large, cause adverse effect.

Sometimes the direction of the load and the size of the can't cut local judgment, for example in high speed rotating machinery, in addition to have to bear the weight of the rotor for direction fixed load and outside, still not balance the load caused by quality spin, if such rotation load much larger than the fixed load, the synthetic load for spin still load; And if rotating load much smaller than the fixed load, the synthetic load for swinging load. No matter the load is still swing rotating load, spindle bearing its size and direction in a constantly changing. And in variable work condition, some rings least load when possible but spin load, but fixed load, and swing when it load. This kind of load called indefinite load.

On the shaft and housings, spindle bearing the requirements in the radial, axial and tangent direction and so on three direction fixed its position. Radial and tangential to bearing the collar position through a tight fit mining realization, axial location only in a few instances the tight cooperation; General use of the axial spacing parts, such as cover and block circle will axial position limit in clearance range.
Choose fit should focus on the pay attention to the following four:

(1) bearing collar circle should have a good face strength evenly and support, to reduce the deformation, and can give full play to the bearing capacity of the INA bearing.

(2) in the rings with the tangent direction along the surface can't slip, can damage otherwise with surface.

(3) the freedom must be able to shaft bearings and housings adapt to changing the length of the hole, that must have to adapt to the axial position in a certain range of swimming ability.

(4) must pay attention to make spindle bearing installation and removal is simple, save work saving time spending. Operation INA bearing, hands sweat will be the cause of rust. To pay attention to use clean hand operation, better try to take the gloves.
