239/850K/W33

239/850K/W33 is a super-large self-aligning roller bearing with a conical inner hole. Its core function is to provide a key component for medium and low-speed heavy equipment that needs to withstand extreme radial loads and certain axial loads, has shaft deflection / installation deviations, and requires flexible installation and long-term lubrication. It achieves self-aligning through the spherical raceway of the outer ring, compensating for equipment operation errors; "K" represents a 1:12 cone angle of the inner hole, suitable for conical shaft necks or installation with a locking sleeve, enhancing installation flexibility; "W33" ensures continuous lubrication with oil grooves and oil holes on the outer ring, reducing wear; with an ultra-large size of 850mm inner diameter, 1120mm outer diameter, and 200mm width, and an extremely high rated dynamic/static load capacity, it precisely fits into harsh working conditions such as large-scale ball mills in mines and heavy steel rolling machines in metallurgy, meeting the requirements of heavy load, easy installation, and long-term operation.
