Powder metallurgy oil-containing bearings are generally made of materials, powders, plastics, etc.; today's machines are mostly automated. The daily output is large; most products can be formed at one time. Therefore, the larger the batch, the better the production. And if the mold used today is less, it may be hundreds of thousands; if more, it may be more than one million. But the cost of the mold is higher; therefore, if the batch is small, it is not good; The time of the mold is also long.
Powder metallurgy oil-impregnated bearings can be formed at one time; they do not have to be machined at all. The cost is lighter than machining; the data is less ruined; the price is therefore cheaper. It also fits the national policy of saving energy today, and is therefore thought to be a no. Will fall behind the skills.
The powder metallurgy oil-impregnated bearing has been filled with lubricating oil by vacuum impregnation in the base body; and it is used because of temperature rise and pumping during operation; the lubricating oil in the process will seep out to the working surface; therefore, it can be used without additional lubrication. The occasion of oil.
