618/560MA

The 618/560MA, as a single row deep groove ball bearing, is primarily designed to meet the upgraded and enhanced special bearing requirements for ultra-large heavy-duty equipment with high precision and demanding working conditions. With its 560mm inner diameter, 710mm outer diameter, and 72mm oversized specification size, the suffix "MA" corresponds to the optimized structure and precision enhancement design. This design not only offers superior load redundancy, resistance to deformation, and operational stability, but also precisely matches the heavy-duty, slight impact, and precise positioning requirements in ultra-large mechanical transmissions. It can stably withstand radial loads and bidirectional axial loads, balancing long-term durability and high-precision operation performance. It uses high-carbon chromium bearing steel (with enhanced treatment to improve wear resistance and fatigue resistance) and high-strength precision cages, suitable for medium and low-speed high-precision transmission scenarios. Installation and maintenance are convenient, and it can be easily integrated into ultra-large core transmission systems without complex adaptation. It is widely used in heavy machine tools with high-precision spindles, metallurgical large-scale precision rolling mills, ultra-large precision reduction devices, power giant rotor high-precision supports, and mining heavy precision equipment, providing reliable support for the smooth, precise, and long-term operation of equipment in ultra-large heavy-duty high-precision scenarios.
