With the continuous improvement of industrial automation, the requirements for bearing materials are becoming higher and higher, especially for high-speed bearings, ultra large bearings, and long-life bearings, which have particularly high performance requirements for bearing materials. Powder metallurgy, as a rapidly developing material processing technology in recent years, has been widely used in the bearing manufacturing industry. With the support of powder metallurgy technology, the quality of oil bearing has been greatly improved.

Powder metallurgy technology is a process that uses metal powder as raw material and undergoes a series of forming and sintering processes to produce the required parts. Compared with traditional material manufacturing techniques, powder metallurgy technology has the following advantages:

1. The chemical composition of the material is uniform, and the heterogeneity of the metal is low;

2. High dimensional accuracy of the product;

3. Suitable alloying elements can be added to achieve the required physical and chemical properties.

Oil bearing is a material that can self lubricate during operation. Compared to traditional lubrication methods, oil bearing has the following advantages:

1. Able to work in high temperature, high speed, high load, and harsh environments;

2. Stable lubrication, not prone to failure;

3. It can reduce the friction and wear of bearings.

Due to the frequent use of oil containing bearings in harsh working environments, the quality of their materials must be guaranteed. Powder metallurgy technology has become an important way to manufacture high-quality oil containing bearings.

The process of manufacturing oil bearing using powder metallurgy technology can be divided into the following steps:

1. Raw material preparation: Mix metal powder and lubricating oil together to form oily powder.

2. Powder forming: Using billet forming, the powder is formed into the desired shape and size by pressing.

3. Sintering: The formed billet is processed at a certain temperature and time to sinter together, forming a dense part.

4. Processing: After sintering, the bearings are processed and finely repaired to achieve the final required size and accuracy.

5. Oil coating: Apply an appropriate amount of lubricating oil to the surface of the bearing to ensure its lubrication effect during operation.

Oil bearing manufactured through powder metallurgy technology has the following advantages:

1. The oil powder is uniform, and the performance of the bearing is stable;

2. Low friction coefficient reduces bearing wear;

3. High density, improved strength and toughness of bearings;

4. Accurate dimensions can enhance the accuracy of bearings.

Overall, powder metallurgy technology has become an important technology in the manufacturing of oil bearing. Powder metallurgy technology can be used to manufacture oil containing bearings with stable performance, high accuracy, and reliable quality, providing new ideas for the development of bearing materials. With the continuous progress of technology, powder metallurgy technology will play a greater role in the bearing manufacturing industry.
