23020CAK/W33

23020CAK/W33 is a medium-large-sized self-aligning roller bearing with conical holes and enhanced lubrication design. Its core application is to meet the requirements of "easy installation and disassembly, axial offset, heavy load, and long-term lubrication" for medium-large rotating equipment in industries such as mining, metallurgy, and general machinery, such as crusher drive shafts, metallurgical roller tracks, and fan main shafts. The "K" mark indicates that the inner ring has a 1:12 conical hole, which can be paired with a locking sleeve (such as H3020) to achieve quick installation, disassembly, and adjustment of clearance of the bearing on the cylindrical shaft neck, solving the pain point of inconvenient bearing maintenance in large equipment; the "W33" mark means that the outer ring has a ring-shaped oil groove and three oil holes, which can enhance lubrication through continuous oil injection, suitable for harsh working conditions such as dust and high temperature; combined with the structure of double-row spherical rollers + solid brass cage ("CA"), it not only has strong radial load capacity and impact resistance, but also can compensate for the installation misalignment or shaft deformation deviation of the shaft and bearing housing through self-aligning performance, ensuring the stable operation of the equipment in heavy load and high vibration scenarios.
