Thrust ball bearings are developed with the goal of ensuring high-precision axial load bearing. High-carbon chromium-bearing steel is selected for its material and vacuum-refined to remove impurities, ensuring the substrate’s strength and toughness. The shaft and housing washers (core load-bearing components) are precision-machined using surface grinders to achieve a flatness of ≤0.002 mm and a surface roughness of Ra ≤0.1 μm. They are then subjected to full quenching and tempering to enhance wear resistance and dimensional stability.
The rolling elements (steel balls) undergo multiple precision processes: cold heading to ensure initial roundness, heat treatment to increase hardness, rough grinding and fine grinding to refine dimensions, and finally super-finishing to achieve a roundness tolerance of ≤0.001 mm. Cages are manufactured using either stamping (blanking) or solid (precision milling of pockets), depending on requirements, to ensure a precise fit between the pockets and the balls and prevent misalignment during operation.
Assembly is completed in a Class 1000 cleanroom, with specialized tooling controlling axial clearance to ensure uniform contact between the balls, shaft, and housing washers. Finished products undergo axial static load testing, rotating noise testing, and precision verification. The final product is suitable for axial load scenarios such as machine tool spindles and automobile steering systems, achieving “low friction and high stability” axial transmission.
