239/1180CAK

239/1180CAK is a large-sized self-aligning roller bearing with conical holes. Its core function is to provide a key component for medium and low-speed ultra-large heavy equipment that needs to withstand extreme radial heavy loads and certain axial loads, has shaft deflection / installation deviations, and requires flexible installation. This component offers stable support, automatic alignment, and convenient assembly guarantees. It relies on "CA" (symmetrical spherical rollers + inner ring with double flanges + brass machined cage) to enhance the heavy-load bearing capacity, suitable for high-load scenarios of ultra-large equipment; "K" represents a 1:12 cone ratio of the inner hole, which can be tightened with a locking sleeve or directly installed on the conical shaft neck, improving installation flexibility and the adjustment space for centering; the spherical raceway design of the outer ring realizes automatic alignment, compensating for shaft deflection and installation errors. With an ultra-large size of inner diameter 1180mm, outer diameter 1620mm, and width 335mm, and ultra-high rated dynamic/static loads (reference values: dynamic load approximately 23000kN, static load approximately 45000kN), it precisely fits into harsh working conditions such as mining ultra-large ball mills and metallurgical heavy rolling mills, meeting requirements for heavy loads, easy installation, and long-term operation.
