618/560E

The 618/560E is a single row deep groove ball bearing. Its core function is to be a high-performance universal bearing suitable for the precise transmission of ultra-large heavy-duty equipment. With its large specifications of 560mm inner diameter, 710mm outer diameter, and 72mm width, combined with the optimized structural design corresponding to the suffix E, it not only has stronger bearing redundancy and anti-deformation ability, but also can balance the precision rotational accuracy. It can stably withstand radial loads and bidirectional axial loads, effectively adapting to the heavy load requirements and slight thermal expansion scenarios during the operation of ultra-large machinery. It uses high-carbon chromium bearing steel as the main body and high-strength stamping steel cage. The bearing performance meets the core transmission requirements of ultra-large equipment. The speed performance under grease lubrication and oil lubrication is suitable for medium and low-speed stable operation. The structure is simple and the installation and maintenance are convenient. It can be integrated into the transmission system of ultra-large machinery without complex adaptation, and is widely used in heavy machine tool spindles, metallurgical large rolling mills, general machinery ultra-large reduction devices, power equipment giant rotor support, mining heavy equipment, etc., providing reliable support for the precise, stable, and long-term operation of equipment in ultra-large heavy-duty scenarios.
