618/500M

The 618/500M is a single row deep groove ball bearing. Its core function is to be a high-reliability, universal heavy-duty bearing suitable for large-scale machinery in various industries. With a large size of 500mm inner diameter, 620mm outer diameter, and 56mm thickness, and combined with a stable bearing capacity of 315kN for dynamic load and 465kN for static load, it can simultaneously withstand radial load and bidirectional axial load, meeting the core requirements of large equipment in fields such as construction machinery, metallurgy, and power for component bearing and operational stability. It is made of special steel suitable for high-temperature conditions and can be paired with advanced lubrication and sealing technologies to reduce running friction and wear. Under grease lubrication, the reference rotational speed is approximately 800r/min, and under oil lubrication, it is approximately 950r/min, which is suitable for most medium and low-speed heavy-duty scenarios. It also has the advantages of a simple structure and easy installation and maintenance. As a key component for the rotating shaft system of large machinery, it is widely adapted to the transmission structures of various equipment such as machine tools, mining equipment, railway equipment, and petroleum machinery, providing reliable support for the smooth and efficient operation of machinery under various heavy-duty conditions.
