248/1800FA/W20

248/1800FA/W20 is a giant self-aligning roller bearing designed for a 1800mm ultra-large shaft diameter. Its core function is to support the core transmission system of large-scale equipment in industries such as metallurgy and mining, providing highly reliable rotational support for low-speed, heavy-load, and complex working conditions. With an outer diameter of 2180mm and a width of 375mm, the steel solid cage (FA) has strong impact resistance, and the W20 suffix enhances its adaptability to harsh environments. The rated dynamic load is approximately 19800kN, and the static load is approximately 62000kN. It can withstand ultra-large radial and certain axial loads, and can also compensate for shaft bending or installation deviations. The reference rotational speed is approximately 90r/min, and the maximum rotational speed is approximately 180r/min. It is mainly used in heavy steel rolling machines, giant crushers, and other equipment, reducing downtime losses and ensuring continuous operation of the equipment.
