23022CA/W33

23022CA/W33 is a self-aligning roller bearing that integrates heavy-duty bearing capacity, self-centering function and long-term lubrication. Its core positioning is to be suitable for large equipment in industries such as mining, metallurgy, and wind power, which "bear heavy loads + bidirectional axial forces, have misaligned axes and require long-term maintenance-free / low maintenance". Such equipment includes main shafts of crushers, roller systems of rolling mills, and gearboxes of wind turbines, etc. The "CA" marking corresponds to the structure of "symmetrical rollers + inner ring flange + integrated cage", ensuring strong radial and axial bearing capacity, and adapting to harsh working conditions with high impact and vibration; the "W33" marking achieves continuous lubrication through annular oil grooves on the outer ring and three oil holes, addressing the pain points of inconvenient lubrication and high maintenance costs for heavy-load equipment, while retaining the self-aligning function to compensate for installation deviations, and comprehensively ensuring the stability and durability of the equipment in complex working conditions.
