There are many car owners only pay attention to check the oil in the oil, according to the standard add, without paying attention to check the oil quality, the expense of the replacement of oil has changed, resulting in some of the moving parts of the engine is always in poor lubrication operation environment, thus speeding FAG bearing wear.
To enable the machine tool spindle temperature will not be too high and thermal variations occur, affecting the machining accuracy or cause poor lubrication FAG bearings, spindle bearings should be based on the structure, speed and bearing clearance and other appropriate choice of temperature lubricant and require that they have good viscosity-temperature characteristic, to prevent the spindle temperature and environmental temperature change is large, the viscosity change is too large to affect its lubricating properties.
FAG bearings of the spindle and between the contact surfaces to maintain a uniform film, and start or stop the spindle motion of an impact load is not induced destruction of the oil film, and maintain good lubrication to reduce friction and frictional heat plays, reduce the spindle temperature, ensure accuracy role requires a good lubricating properties.
FAG bearings in automotive applications is very broad, lubricant errors mentioned above is just one part. Everyone in the use of this kind of FAG bearings when we must be careful. Do not damage FAG bearings, reducing its life.
