Oil seal ring is a device used to prevent lubricant (such as oil, butter, etc.) from leaking from bearings or seals. It is usually made of elastic material and can be tightly attached to the shaft or bearing to achieve a sealing effect.

Oil seal rings are generally divided into two types: one is a single piece oil seal ring, which only has one ring of oil seal; The other type is a combination oil seal ring, consisting of two or more rings.

Oil seal rings are usually used to seal high-speed rotating shafts, such as motors, reducers, etc. It has a long service life and can withstand the influence of various environmental factors, so it is widely used in industrial production.

When using the oil seal ring, it is necessary to carefully clean the surface of the shaft or sealing element to ensure that the oil seal ring can tightly fit on the surface. At the same time, it is also necessary to check whether the oil seal ring is worn or aged, and if any problems are found, they should be replaced in a timely manner.
