618/750

The 618/750 is a large-sized single-row deep groove ball bearing. Its core function is to provide high-precision rotational support with low friction, high rotational speed, and strong load adaptability for large-scale machinery in multiple fields such as steel mills, metallurgy, mining machinery, and power equipment, which are used in high-temperature operations. With a 750mm inner diameter, 920mm outer diameter, and 78mm width, and equipped with a brass cage and open structure design, it has a basic rated dynamic load of 527kN and a basic rated static load of 1250kN. It can stably withstand the main radial load and also bear a certain amount of axial load. After increasing the radial clearance, it can also possess the characteristics of angular contact ball bearings to cope with larger axial loads, meeting the requirements of complex load conditions in various scenarios. This bearing has a low friction coefficient, with a maximum rotational speed of up to 1100r/min. The reference rotational speed is 900r/min, which can meet the requirements of high-speed operation of large equipment. Its structure is simple, installation is convenient, and maintenance requirements are low. Even when the angle between the outer hole of the housing and the shaft is within 8° - 16°, it can still operate normally. It can be adapted to the operation conditions of various machinery such as mine conveyors, power plant motors, steel mill kilns and kiln trucks, and high-speed fans, providing reliable support for the smooth operation and low-noise, low-vibration operation of these equipment. It is a key core component with strong adaptability and high stability in the general machinery field and high-temperature operation machinery.
