The spherical roller bearing process focuses on the core requirements of “heavy-load adaptability + automatic self-alignment,” ensuring high performance through high-precision machining. Highly fatigue-resistant bearing steel is selected for its material, which undergoes refinement to remove impurities and enhance the toughness of the matrix. The double-row spherical rollers utilize a “cold heading → fine grinding → super-finishing” process, with a spherical surface curvature tolerance of within 0.005mm, ensuring synchronized contact between the two rows of rollers and the raceways.
Rings are machined using a five-axis CNC grinding machine, achieving geometric accuracy of IT4 for both the inner ring double raceway and the outer ring spherical raceway, ensuring smooth contact during automatic self-alignment. Key areas undergo carburizing and quenching followed by low-temperature tempering to enhance surface wear resistance and core toughness.
Diametrical clearance is precisely controlled during assembly, and a stamped or solid cage is used to achieve uniform roller distribution. The finished product undergoes dynamic balancing, rotational noise, and load life testing. Ultimately, it is suitable for heavy and uneven load applications such as mining machinery and papermaking equipment, fully leveraging the value of the process’s “automatic compensation for coaxiality errors.”
