Custom Spherical Plain Bearing

In the process of machining spherical bearings, how to ensure the precision and fit of the inner and outer rings, raceways and rolling elements of the bearings?

YININ Company is well aware that high-precision machining equipment is the basis for precision manufacturing of bearings. Therefore, our workshop is equipped with modern manufacturing equipment, including but not limited to high-precision CNC lathes, grinders, superfinishing machines and automated assembly lines. These equipment not only greatly improve the machining efficiency, but more importantly, they can ensure that the dimensional accuracy and shape accuracy of the inner and outer rings, raceways and rolling elements of the bearings reach the micron level or even higher.
High-precision CNC lathe: used for preliminary machining of the inner and outer rings of the bearings, through precise programming control, to ensure that the machined parts have consistent size and regular shape.

High-precision grinder: further precision grinding of the inner and outer rings and raceways of the bearings to achieve the surface roughness and dimensional accuracy required by the design.
Superfinishing machine: superfinishing the raceways to eliminate microscopic unevenness, improve surface quality, reduce friction coefficient and extend the service life of the bearings.
Automated assembly line: through precise assembly robotic arms and sensors, accurate assembly of rolling elements is achieved to ensure that the fit meets the design requirements.
YININ has established a complete quality control system. From raw material procurement to finished product delivery, each process is strictly inspected and tested.

Raw material inspection: All raw materials must undergo chemical composition analysis, physical property testing and non-destructive testing to ensure that the material quality meets the standards.
Online monitoring: During the processing, advanced online monitoring technologies such as laser ranging and vibration analysis are used to monitor the processing accuracy and surface quality in real time.
Finished product inspection: After each process, we will conduct corresponding inspections, including dimension measurement, shape inspection, surface roughness inspection, etc. For the finished products, we will conduct full inspections according to customer requirements and international standards, including but not limited to rotation tests, load tests and life tests to ensure that the bearings perform well in actual applications.
YININ not only focuses on the optimization and improvement of existing technologies, but also actively invests in research and development to promote technological innovation. Our technical team consists of 12 experienced technicians who are committed to solving technical problems in bearing manufacturing and improving product performance.

Material innovation: Continuously explore the application of new materials, such as high-performance alloy steel, ceramic materials, etc., to improve the wear resistance, corrosion resistance and high temperature resistance of bearings.
Structural optimization: Through computer-aided design (CAD) and finite element analysis (FEA), the bearing structure is optimized to improve the load-bearing capacity and running stability.
Customized service: With rich experience and profound technical background, we are able to provide customized bearing solutions according to the specific needs of customers. Whether it is a bearing of special size, a bearing of special material, or a bearing with special performance requirements, we can meet them one by one.
The assembly process of the bearing also has a crucial impact on the precision and fit. YININ uses advanced assembly technology and equipment to ensure the precise fit of the various components of the bearing.

Precision measurement: Before assembly, use high-precision measuring tools to accurately measure the various components of the bearing to ensure consistent dimensions.
Cleaning treatment: Strictly clean the various components of the bearing to remove impurities such as oil and dust to avoid contamination during the assembly process.
Preload and adjustment: Preload and adjust the bearing according to the design requirements to ensure that the bearing has appropriate preload and fit clearance during operation.
Dynamic detection: After assembly, the bearing is dynamically tested, including the test of indicators such as rotation flexibility, vibration and noise, to ensure that the bearing performance meets the design requirements.
