The advantages of oil-impregnated bearing:
1.Oil-impregnated bearing belongs to porous product, and the number, size, shape and distribution of holes can be adjusted
appropriately during processing.
2.Bearing holds good vibration absorption caused by the unique porous property.
The lubricating oil can be impregnated in the gap, so as to realize the self-supply of  oil, and it can be operate normally
without adding lubricating oil under long-term working.
3.The loadding capacity, eccentricity, and friction coefficient of the oil-impregnated bearing all affect each other during operation.
Therefore, various requirements of the bearing can be met by properly adjusting these parameters.
