23980MB/W33 is a double-row self-aligning roller bearing with dimensions of 400×540×106 mm. It features a copper cage MB structure and an outer ring with oil grooves and oil holes W33 design. The rated dynamic load is 2200 kN, the static load is 3900 kN, and its weight is 72.4 kg. It possesses high load-bearing capacity, self-aligning property, and impact resistance. It is specifically designed for heavy-duty, high-temperature and dusty working conditions such as metallurgical rolling mills and mining crushers. It can operate stably for a long time at positions with shaft deflection or large installation errors, and is a reliable choice for key parts such as large rotary kilns and supporting rollers of reducers.
