618/560M

The 618/560M, as a single row deep groove ball bearing, is primarily designed to be an enhanced general-purpose bearing suitable for complex working conditions of ultra-large heavy-duty equipment. With a 560mm inner diameter, 710mm outer diameter, and a super-large specification size of 72mm, it is combined with the optimized structure and performance enhancement design corresponding to the suffix M. It has more sufficient bearing redundancy, impact resistance, and adaptability to working conditions, and can stably bear radial loads and bidirectional axial loads. It effectively responds to heavy loads, slight thermal expansion, and complex stress scenarios during the operation of ultra-large machinery, balancing operational stability and durability. It is equipped with a high-carbon chromium bearing steel core and a high-strength cage configuration, suitable for medium and low-speed precision transmission requirements. It is easy to install and maintain, and is widely used in heavy machine tools, large-scale metallurgical rolling mills, ultra-large reduction devices, power giant rotor supports, and heavy mining equipment, providing reliable support for the long-term smooth operation of equipment in ultra-large heavy-duty scenarios.
