Production Process

American UPX Bearing Group Co., Ltd. adheres to exquisite craftsmanship and strict quality control standards in the production process of bearings to ensure that each bearing can achieve excellent performance and quality. The following are the main technological processes of the company's bearing production:

● Material preparation

Raw material procurement：According to the type and specifications of the required bearings, high-quality steel is carefully selected as the raw material. These steels are subject to strict quality inspection to ensure that their physical properties, chemical composition, etc. meet the production requirements.

Quality Inspection：Conduct a comprehensive quality inspection of the purchased raw materials, including appearance inspection, dimensional measurement, chemical composition analysis, etc., to ensure that the raw materials are free of defects and impurities, laying a solid foundation for the subsequent processing process.

● Blank processing

Cut off：The qualified raw materials are cut according to the specified length to form a preliminary blank.

Heat treatment：Heat treatment of the cut billet, such as annealing and normalizing, is performed to improve its internal structure and properties and to facilitate subsequent processing.

● Inner and outer ring processing

Forging：The billet after heat treatment is put into the forging equipment, and the blank of the bearing ring is formed through the forging process. The forging process can significantly improve the compactness and streamlining of the raw material, thereby improving the reliability and service life of the bearing.

Car processing：The rough after forging is finely processed by lathe to form the key dimensions such as the inner diameter and outer diameter of the bearing.

Heat treatment：After machining the bearing ring for high temperature treatment, such as quenching, tempering, etc., to improve its hardness and wear resistance.

Grinding：Grinding the bearing ring after heat treatment to ensure that its dimensional accuracy and surface finish meet the design requirements. After grinding, the production process of the bearing ring is basically completed.

● Ball or roller machining

Cold heading：For steel balls, a cold heading machine is usually used to break the wire or bar into ball embryos.

Heat treatment：Heat treatment is performed on the formed steel ball to improve its hardness and wear resistance.

Grinding and Grinding：After heat treatment, the steel ball is ground and ground several times to ensure that its dimensional accuracy and surface finish meet the design requirements.

● Cage processing

Stamping or physical processing：According to the design requirements, the cage is made by stamping or solid processing. Stamping is suitable for thin plate materials, while solid processing is suitable for applications requiring higher strength and rigidity.

Finishing：Finish the processed cage, such as deburring, pickling, etc., to improve its surface quality and assembly accuracy.

● Bearing assembly

Parts cleaning and demagnetization：All machined bearing parts are cleaned and demagnetized to remove impurities and residues and eliminate magnetic effects.

Assemble：Assemble the inner ring, outer ring, steel ball (or roller) and cage in the correct order and method to form a complete bearing.

Clearance check：Check the clearance of the assembled bearing to ensure that its performance meets the design requirements.

● Cleaning and quality inspection

Cleaning：The assembled bearings are thoroughly cleaned to remove all impurities and residues.

Quality Inspection：Conduct a comprehensive quality inspection of the cleaned bearings, including visual inspection, dimensional measurement, performance testing, etc., to ensure that their quality meets standards.

● Packaging and factory delivery

Packaging：For bearings that have passed the inspection, packaging materials such as plastic bags and boxes are usually used, and labels are attached to indicate product information and production dates.

Factory inspection：The final inspection of the packaged bearings is carried out before leaving the factory to ensure that they are correct before leaving the factory for sale.
