Упорные цилиндрические роликовые подшипники

The manufacturing process for thrust cylindrical roller подшипники focuses on “high axial load and impact resistance.” Высокопрочная подшипниковая сталь, устойчивая к усталости. is selected for its material, which undergoes vacuum refining to remove impurities, ensuring the matrix’s strength, toughness, and microstructure uniformity. The washers, core load-bearing components, are machined using high-precision surface grinding to a flatness of ≤0.002 mm and a surface roughness of Ra ≤0.1 μm. They are then subjected to through-hardening and tempering to enhance wear resistance and dimensional stability.

Roller processing requires multiple precision steps: cold heading to ensure the foundation of cylindricity, precision grinding of the cylindrical surface to an IT3 diameter tolerance, and super-finishing of the end faces to achieve parallelism of ≤0.001 mm, ensuring a uniform contact with the washer and avoiding localized stress concentrations. The cage is constructed using either sheet metal stamping or solid milling, with precisely machined pockets to secure the rollers and prevent misalignment during operation.

Assembly is completed in a Class 1000 cleanroom, using specialized tooling to achieve uniform roller alignment and precisely control axial clearance. The finished product undergoes axial static load testing, rotating wear verification, and precision testing. The final product is suitable for large axial load scenarios such as heavy machinery and wind power equipment and relies on its technological advantages to achieve the transmission requirements of “high load capacity and long life.”
