239/850/W33

239/850/W33 is a super-large self-aligning roller bearing. Its core function is to provide a key component for medium and low-speed super-large heavy equipment that requires long-term lubrication, stable support, automatic alignment, and low maintenance, especially when it comes to extreme radial loads, shaft deflection, installation deviations, and where long-term lubrication is necessary. It achieves automatic alignment through the spherical raceway design of the outer ring, compensating for installation errors and shaft deformation during equipment operation. The "W33" outer ring oil groove and oil hole structure ensures continuous lubrication and reduces wear. With an outer diameter of 850mm, outer diameter of 1120mm, and width of 200mm, it has an ultra-large size and extremely high rated dynamic/static loads, precisely adapting to harsh working conditions such as super-large ball mills in mines, heavy-duty steel rolling machines in metallurgy, and cement rotary kilns. It meets the requirements of heavy loads, strong adaptability, and long-term operation.
