The production process of spherical roller bearings of FV bearing

Nov 30, 2023

Spherical roller bearings are commonly used in the metallurgical, cement, and wind power industries. Due to their self-aligning ability, they can adapt to misalignment. When the shaft or bearing seat is relatively tilted, it typically works. So, it is widely used in the above industries. The production process of spherical roller bearings is complex and delicate, involving multiple links and processes. The following overviews of the spherical roller bearing production process include raw materials, design, heat treatment, grinding, and assembly.

Raw materials

The production of spherical roller bearings begins with the preparation of raw materials. Usually, the raw materials of bearings include bearing steel, chromium steel, nickel steel and other high-quality steels. These steels must be processed into sizes and shapes suitable for production through forging, cutting, grinding and other processes. In the manufacturing process, the quality and precision of the raw materials play a crucial function in determining the final product's quality.

Design

The design link is to carry out the structural design, performance design and appearance design of the bearing based on customer needs and market requirements. During the design process, factors such as bearing capacity, life, friction resistance, noise, etc., need to be considered, as well as product appearance, size, accuracy and other requirements. The design link is the soul of the entire production process, which determines the quality and performance of the product.

Heat treatment

The heat treatment link is vital in producing spherical roller bearings, which directly affects the hardness and wear resistance of the product. The heat treatment includes three stages: heating, insulation, and cooling. Changing the material's internal structure is achieved by controlling parameters such as heating temperature, insulation time, and cooling rate. After heat treatment, steel's hardness and wear resistance will be significantly improved.

Grinding

The grinding link is vital in bearing production, affecting the product's accuracy and performance. In this link, the workpiece is fixed on the grinder, and through the high-speed rotation of the grinding wheel and the feed motion of the workpiece, the surface of the workpiece is ground to the required shape and precision. The grinding process has a vital impact on the accuracy and performance of the product. Improper grinding will lead to reduced product accuracy or unstable performance.

Assembly

The assembly link is assembling various parts to form a complete bearing. In this link, the inner ring, outer ring, rolling elements, cage and other components must be assembled in a particular order and method, and operations such as lubrication and sealing must also be performed. The assembly link has a vital impact on the performance and quality of the product. Improper assembly will lead to unstable product performance or shortened service life.

Detection and Testing

After completing the above links, the product must be checked and tested to ensure it meets the design requirements and customer needs. The inspection and testing links include appearance inspection, dimensional inspection, accuracy inspection, performance test, etc. These inspections and tests can identify product problems and make timely corrections to ensure the best quality and performance of the product.

Packaging and transportation

Finally, the spherical roller bearings that pass the inspection and testing must be packaged and transported. Packaging aims to protect the bearings from damage during transportation while improving the product's aesthetics. Packaging materials generally use cartons or wooden boxes selected according to the product type and customer needs. After packaging is completed, the product must be transported to the customer through logistics or express delivery. During this process, attention must be paid to preventing the product from being subject to vibration or collision during transportation to ensure that the product is intact.

Summary: The production process of spherical roller bearings is complex and delicate, involving multiple links and processes. Each link has an essential impact on the quality and performance of the product, so the quality and accuracy of each link need to be strictly controlled during the production process. At the same time, with the continuous development of science and technology, new technologies and new processes are constantly being applied to the production of bearings, which provides more possibilities for improving product performance and quality. In the future, as market competition continues to intensify, spherical roller bearing manufacturers need to continuously improve their technical level and innovation capabilities to adapt to market changes and customer needs.
