Bearing is the key mechanical base parts, the quality of its quality directly affects the quality of the host, a wide variety of bearings, in many varieties, a large quantity of wide sealed deep groove ball bearings occupy its important position, in China, the output of sealed bearings accounts for about 70% of the total number of deep groove ball bearings.

Seal bearings are widely used in electromechanical equipment, household appliances, instruments, office automation equipment and so on. For this kind of bearing, not only requires the selected grease to have good lubrication performance, its life is the same as the bearing life, but also has the effect of reducing bearing noise and the degree of environmental friendliness.

Sealing bearing lubricating oil requirements are:

1, wide temperature range, high temperature and high speed conditions, long service life;

2, rotating friction torque and bearing temperature rise is small;

3, small noise and vibration when rotating, and not easy to produce abnormal sound;

4, with excellent leakage;

5, with good rust resistance, when used in motor bearings, can prevent corrosion caused by insulating paint.
