When we use the bearings, need special primary environment in some people because of the bad bearing operating conditions cause damage to bearings, SKF bearing environment particular attention needs also, of course, is to use the environment as some of the best.
According to the location and conditions of use and environmental conditions select size, accuracy, combined with suitable bearing is a precondition to guarantee bearing service life and reliability.
1, used parts: SKF bearings are suitable to withstand radial load-oriented combination of radial and axial load, usually with two sets of paired bearings, mainly on the front and rear wheels of the car, the active cone transmission parts such as gears, differentials, gearbox.
2, allows speed: correctly installed, lubrication good environment, allow for bearing limit rotational speed of 0.3 per cent. Under normal circumstances, to 0.2 times the speed limit for the most desirable.
3, allowing tilting SKF bearings are generally not allow tilting axis relative to the shell hole, such as tilt, maximum not more than 2.
4, the allowable temperature: under normal load and high temperature performance of lubricants and lubrication under adequate conditions, General bearings allow at-30 ° c-150 ° c ambient temperature.
Advantages of bearings:
1 friction resistance is small, small power consumption, high mechanical efficiency, easy to start;
2, size standardization of interchangeability, easy to install and disassemble, easy maintenance;
3, compact structure, light weight, axial dimensions are more reduced;
4, high precision, high speed, low abrasion, long service life;
5, some bearings are auto-new performance;
6, suitable for mass production, the quality is stable and reliable, high production efficiency　　
Disadvantages of rolling bearings:
1, big noise　
2, bearing blocks have a complex structure
3, higher costs
