Oil bearing is used in many kinds of mechanical equipment, such as motor industry, steam and friction industry, household appliance industry, digital products, office equipment, electric tools, textile machinery, packaging machinery and other kinds of machinery and equipment.

Generally speaking, powder metallurgy oil bearing is made of raw material, pressed, sintered, reshaped and immersed in oil. Most of the machines nowadays are highly automated. The daily output is relatively large, most products can be formed at a time, so the larger the batches, the better the production. Now, if we use fewer moulds, we may make hundreds of thousands of them. But the cost of mold is relatively high, so it will not be done if there is a lot of volume, and the time to change the mold is also long.

Generally speaking, powder metallurgy oil bearing can be formed at one time, basically without cutting. Cost is lighter than machine processing, material waste is less, and price is cheaper. It is also consistent with the national policy of promoting energy conservation. Therefore, it is considered to be a technology that will not outdated.

The base of powder metallurgy bearing oil bearing has been filled with lubricating oil in the vacuum immersion method, and the lubricating oil will exudate to the running surface because of the temperature rise and pump suction in operation, so it can be used in the situation of not adding the lubricating oil.
