Characteristics of powder metallurgy oil bearing

Powder metallurgy oil-containing bearings are generally manufactured by using raw material powders through pressing, sintering, shaping, and oil immersion processes. Most of today's machines are highly automated. The daily output is relatively large, and most of the products can be formed at one time, so the larger the batch, the better the production. Moreover, if the number of molds used now is less, it may be hundreds of thousands, and if it is more, it may be more than one million. However, the cost of the mold is relatively high, so if the batch size is small, it is not easy to do, and the time for replacing the mold is long.
     Powder metallurgy oil-impregnated bearings are generally formed at one time and are basically not machined. The cost is lighter than machining, the material waste is less, and the price is therefore cheaper. It is also in line with the current national policy of promoting energy conservation, so it is considered to be a technology that will not fall behind.
     The powder metallurgy oil-impregnated bearing has been filled with lubricating oil by vacuum impregnation in the base body, and the lubricating oil will seep out to the running surface due to temperature rise and pumping during operation, so it can be used without additional lubricating oil. The occasion.
