First, to the mounting surface and installation place requirement is
Bearings inside can t impurity in, if there were scrap iron and bearing dust and impurities in,thin bearing will make bearing in turns noise and vibration, can have even groove roller bearing damage cause damage. So, in the installation of bearing before, to ensure the installation surface and installation of the environment clean.
Second, bearing before installing to clean?
Bearing is coated with temporary, before the installation, should use clean gasoline or kerosene careful cleaning, besmear again clean quality to lubricate the grease can install and use. To the service life of the bearings cleanness and noise are a very big effect. But must special remind: fully enclosed bearing (with dust cover or seals bearing) is not cleaning refueling.
Third, how choice lubricating grease?
The stand or fall of lubrication serious influence bearing rotation and life expectancy, generally choose grease principle is: by base oil, grease thickening agent and additives of composition, different kinds of different kind s of the or the same brand of grease performance can vary widely, allow limit speed of different, when the choice should pay attention to. The performance of the grease mainly by base oil decided, generally low viscosity base oil is suitable for low temperature, high speed environment,thin section ball bearing high viscosity suitable for high temperature, high load operation environment. Thickener also relates to the lubrication performance, thickener water resistance decided to grease water resistance. In principle, different brand grease should not be mixed use, and even the same kind of thickening agent of grease, because different additives on bearing brings bad influence.
Fourth, in the lubrication bearing, grease the more the better?
Lubricating bearings, oil and not besmear so that the more the better. Bearings inside much oil will cause of grease overmix, theref ore cause temperature was too high. Bearing grease filling the number of internal space to fill the bearing 30% ~ 50% advisable.
Sixth, bearing radial clearance smaller may be more beautiful?
Not all of the use of the environment are required to have the smallest work bearing clearance, you must be under conditions of use, we choose the suitable clearance. Gb 4604-93, rolling bearing radial clearance is divided into 5 groups: two groups, 0 group, the three groups, 4 group, five groups, clearance value from small to large arrangement, where 0 group for the standard common clearance. Standard radial clearance group applicable to the general operation conditions, conventional temperature and the commonly used over surplus cooperation; In high temperature, high speed, low noise, low friction under special conditions such as work should be the chooses big bearing radial clearance; For precise spindle, spindle bearing appropriate chooses the smaller radial clearance.thin section ball bearings
