239/900CAF1/W33

239/900CAF1/W33 is a super-large self-aligning roller bearing with a special cage. Its core function is to provide a key component for medium and low-speed super-large heavy equipment that needs to withstand extreme radial heavy loads and certain axial loads, with shaft deflection / installation deviation, and requires high stability of the cage and long-term lubrication. It offers stable support, automatic self-aligning, and durability guarantees. It achieves enhanced load-bearing stability through the "CA" cast cage + symmetrical spherical rollers, the "F1" special cage (mostly in solid structure) suitable for high-load scenarios of super-large bearings, and the "W33" oil groove and oil holes for continuous lubrication. With an ultra-large size of 900mm inner diameter, 1180mm outer diameter, and 210mm width, and a dynamic load of approximately 8800kN, static load of 19000kN (reference value), and a reference rotational speed of 260r/min, it precisely fits into harsh working conditions such as mining super-large ball mills and metallurgical heavy rolling mills, meeting requirements for heavy load, strong compatibility, and long-term operation.
