Industrial robot bearings need to meet the P2-P5 precision standards, involving processes such as thin-walled deformation control and precision assembly. Domestic products still have a gap in lifespan (about 8000 hours) and accuracy retention compared to imported products. Manufacturing bases have been established in Luoyang and other places in China, and some enterprises have achieved mass production of RV reducer bearings with an axial stiffness of 1800N/μ m, gradually promoting domestic substitution[
