Bearings are complex and complicated. Some sell for a few dollars and some sell for hundreds of dollars. The bearings don't look much different, so why is there such a big price difference?
According to the mechanism of lubrication, the viscosity of the lubricating base oil directly affects the formation of the lubricating oil film. Specifically, for the same speed and load, the high viscosity of the lubricating base oil is conducive to the formation of the oil film.
Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The silent bearing is mainly used in household appliances that are closely
In production, there is often a fever of rolling bearings. If the cause analysis is not clear, the treatment is not timely and the measures are inappropriate, it will take twice the effort and half the effort, and even lead to bearing burnout, gear reducer teeth beating and other malignant accidents
The performance of precision bearings requires that small friction when the rotating body has high run out precision and high speed rotation. In this case, precision bearings are divided into P0, P6, P5, P4 and P2 according to ISO classification standards. P0 bearing is normal precision.
