The thrust needle roller bearing process focuses on “high axial load capacity combined with a compact structure.” Highly fatigue-resistant bearing steel is selected for its material, which undergoes vacuum refining to remove impurities and ensure the base material’s strength and toughness. The washers, the core bearing elements, are precision-machined using surface grinding to achieve a flatness of ≤0.002 mm and a surface roughness of Ra ≤0.2 μm. They are then quenched and tempered to enhance wear resistance.
Needle roller processing requires multiple precision steps: cold heading to ensure cylindricity, fine grinding of the cylindrical surface to achieve an IT3 diameter tolerance, and ultra-finishing of the end faces to control parallelism and ensure a tight fit with the washers. During assembly, specialized tooling is used to ensure uniform needle roller arrangement and precise alignment of the washers to avoid uneven loading.
The finished product undergoes axial static load testing, rotational wear verification, and precision testing to ensure stable transmission under axial loads. The final product is suitable for compact applications such as machine tool spindles and automotive transmissions, leveraging its advanced process to meet the core requirements of “small size and high axial load capacity.”
