AI Technical Summary
Large-sized cylindrical bearing rollers face challenges in processing difficulty, increased weight, and material costs due to their large wall thickness, which hinders efficient hardening and surface profiling, especially in machinery like wind turbines and rolling mills.
The bearing roller design incorporates grooves on circular end faces with specific ratios and configurations, such as spherical segments and conical surfaces, to reduce weight, increase heating area for better hardening, and simplify processing.
The groove structure reduces weight and processing difficulty, enhances hardening efficiency, stabilizes operation, and lowers material costs while maintaining structural integrity and reducing inertia.

Technical Field
[0001] The utility model relates to a bearing roller. Background Art
[0002] Bearings are important components in mechanical equipment, and cylindrical bearing rollers are widely used in mechanical equipment. For some major equipment machinery, such as wind turbines, rolling mills, etc., the cylindrical bearing rollers are relatively large in size, and the roller size is also increased accordingly. For large-sized rollers, their weight increases and the processing difficulty becomes greater. Large-diameter rollers cannot be hardened through conventional materials due to their large wall thickness. The material needs to be improved to improve the hardenability, which leads to increased material costs. In addition, it is difficult to process the surface profile of large-diameter rollers, which is inefficient. Utility Model Content
