Aubearing Bearing Materials
Aubearing miniature bearings meet the needs of a variety of complex applications with their diverse material options. Each material has its own unique performance advantages and can adapt to different working environments and requirements. The main materials used in Aubearing include high carbon chromium steel (Gcr15), stainless steel (304, 316, 440C), ceramics (SiCC, Zirconia, Si3N4), plastic (POM), etc.
Aubearing advanced heat treatment process
Aubearing uses advanced heat treatment processes in the manufacturing process of bearings to improve bearing performance and service life. The main heat treatment technologies include vacuum quenching, low-temperature tempering and cryogenic treatment. These processes can significantly improve the hardness, wear resistance and fatigue resistance of bearings.
Vacuum quenching
Vacuum quenching is carried out in an oxygen-free environment, which can effectively avoid oxidation and decarburization, ensure the surface hardness and internal structure of the bearing are uniform, and improve the fatigue resistance of the bearing.
Avoid oxidation and decarburization: Quenching in a vacuum environment can avoid oxidation and decarburization problems that may occur during traditional quenching and ensure bearing surface quality and performance.
Improve hardness and strength: Vacuum quenching can significantly increase the hardness and strength of the material, allowing the bearing to maintain stable performance under high loads.
Application fields: This process is widely used in high-precision and high-load industrial equipment, such as machine tools, automotive parts, and aerospace equipment.
Low temperature tempering
The low-temperature tempering process can eliminate the internal stress generated by the bearing during the quenching process, enhance the toughness and impact resistance of the bearing, and extend its service life. The main features of low temperature tempering include:
Eliminate internal stress: Low-temperature tempering can effectively eliminate the stress inside the material and avoid bearing damage and failure caused by stress concentration.
Improve toughness and impact resistance: Low-temperature tempering can improve the toughness of the material, allowing it to withstand higher impact loads and is suitable for applications with large dynamic loads.
Application areas: Low temperature tempering is often used in equipment requiring high toughness and impact resistance, such as automotive transmission systems and heavy machinery.
Cryogenic treatment
Cryogenic treatment further improves the dimensional stability and wear resistance of bearing materials by cooling them to extremely low temperatures, which is particularly suitable for high-precision and long-life applications. The main advantages of cryogenic treatment include:
Improve dimensional stability: Cryogenic treatment can eliminate residual stress inside the material and improve the dimensional stability and processing accuracy of the bearing.
Enhance wear resistance: Cryogenic treatment can significantly improve the wear resistance of materials and extend the service life of bearings. It is especially suitable for equipment with high load and high speed operation.
Application fields: This process is widely used in precision machinery, high-speed spindles and aerospace equipment, and can meet application scenarios that require extremely high bearing performance.
Aubearing Mminiature Cearing Quality Inspection
In order to ensure product quality, Aubearing strictly implements international standards during the production process and uses advanced testing equipment to conduct comprehensive inspections on each bearing. The main testing methods include non-destructive testing, dimensional measurement and life testing, which can ensure that the bearings meet strict quality requirements in all aspects.
Non-destructive testing
Non-destructive testing technology can effectively detect defects such as cracks and pores inside the bearing, ensuring that the internal quality of each bearing meets the standard requirements.
Ultrasonic testing: Ultrasonic testing can effectively detect defects such as cracks, pores and delamination inside the bearing to ensure the integrity of the material.
X-ray testing: X-ray testing can intuitively display the structure and defects inside the bearing, and is particularly suitable for detecting internal defects of complex shapes and high-density materials.
Application areas: Non-destructive testing is widely used in high-safety and high-reliability equipment, such as aerospace, nuclear industry and high-precision machinery.
Dimension measurement
Use high-precision dimensional measurement equipment to ensure that the size of each bearing is accurate, meets the design requirements, and ensures the assembly performance and operating stability of the bearing.
Three-coordinate measurement: The geometric size and shape of the bearing can be accurately measured by three-coordinate measurement to ensure that it meets the design requirements.
Optical measurement: Optical measurement technology can measure the size and shape of the bearing non-contactly, especially for small and complex-shaped bearings.
Application areas: Dimension measurement is widely used in high-precision and high-demand equipment, such as electronic equipment, medical equipment, and automation equipment.
Life test
By simulating actual working conditions, life tests are carried out to evaluate the service life and performance of the bearing to ensure that it can operate stably in various application scenarios.
Accelerated life test: By accelerating the working conditions of the bearing, its life and performance in actual use can be quickly evaluated and its service life can be predicted.
Fatigue test: Fatigue test can evaluate the performance and life of the bearing under repeated loads to ensure its reliability under high loads and high frequencies.
Application areas: Life tests are widely used in equipment that requires high reliability and long life, such as automobiles, aerospace, and industrial machinery.
