Notes should be paid attention to in the use of imported bearings mainly has 4 aspects, so that the bearing work better, with the following.
Selection and control 1, shaft and bearing tolerances
Press bearing bearing should be flexible rotation not block a sense of. If there is obviously the rotation is not flexible, indicates that the axial size is too large, the tolerance to cut. Assembly, bearing 2 Because the import bearings are precision products, such as improper assembly is easy to bearing raceway damage, cause damage to the bearing.
Bearing assembly shall have the special mould, can not be beat, after pressing shaft when only small force, force pressure when only circle circle.
The assembly by pneumatic or hydraulic press, in the upper and lower touch to outside in the horizontal state, if tilt will cause the bearing channel due to the stress damage, and the bearing guide ring.

Bearing easily mounted to the rotor dynamic balance when the dynamic balance of iron filings into import bearings inside, so it is best to install bearing dynamic balancing.
Some manufacturers in order to convenient assembly, the assembly of some oil or grease lubrication effect in the bearing chamber painted, but the operation is often difficult to control, if the oil or grease in the bearing chamber accumulates more, in the bearing rotates easily along the shaft into the bearing internal.

Bearing is not the best oil or grease, such as non coated not to control may not be in the bearing chamber of accumulation.
4, paint, rust prevention
Paint rust is characterized by multiple sealed type motor, the motor voice in the assembly is very good, but in some time within the warehouse, the electrical noise change greatly, remove bearing with serious rust. Many manufacturers are considered to be before the problem of the bearing, motor factory is now aware of the main insulation paint problem, the problem is mainly because the acidic material insulating paint volatile out of the formation of corrosive substances under certain temperature, humidity, the bearing groove corrosion induced damage of bearing. The problem can only be good choice of insulating varnish, and after drying ventilation for a period of time after the assembly.
The life of the bearing and manufacture, assembly, use are closely related, must be in each link all ready, only in the use of imported bearings pay attention to these considerations, in order to make the bearing in the best running state, thereby prolonging the service life of the bearing.
In order to ensure the bearing has been to the state functioning, maintenance regularly is necessary, so as to achieve the prevention of accidents and preventive measures, improve the production efficiency, save the cost of enterprises. To maintenance work in bearing professional here, there must be a standard system of workflow, including the operation state, lubricant, periodic removal, noise, temperature detection and so on a series of.
Use of the bearing in the specification, all the way to the bearing end of life. This situation is relatively small, usually in the operation of the production process for a variety of reasons causing damage to the bearing, serious direct bearing scrapped off, the cause of these reasons, the use of the installation, lubrication of these three aspects, common have imported bearing ring gear edges of trauma, the main reason is the lack of lubrication or foreign matter. To solve these problems must first rule out the cause of the accident, several aspects using environment, location, structure and so on to examine a similar accident to happen again, bring needless trouble.
