23030F3/W33

The 23030F3/W33 is a reinforced self-aligning roller bearing. Its core function is to provide a highly stable rotating support with superior load-bearing capacity and continuous lubrication assurance for heavy-duty equipment in the metallurgy, mining, and construction materials industries that require long-term heavy-duty operation and do not allow frequent shutdown for maintenance. This bearing maintains the specifications of 150mm inner diameter, 225mm outer diameter, and 56mm width. The suffix F3 brings a reinforced roller arrangement and thick cage design, which can evenly distribute heavy and impact loads by increasing the number of rollers, optimizing dimensions, and thickening the cage thickness, thus avoiding damage to the core components. The suffix W33 corresponds to the outer ring's circumferential oil groove and three evenly distributed oil holes structure, which can achieve continuous lubrication through an external oiling device, solving the problem of lubrication supply for long-running equipment and preventing lubricating grease from drying out and rusting. It resolves the issues of shaft deflection and installation deviation through the self-aligning structure of two rows of rollers and spherical outer ring raceways. It can withstand both bidirectional heavy axial loads and extremely large radial loads. Combined with GCR15 high-carbon chromium bearing steel and professional quenching and heat treatment, it further enhances wear resistance and fatigue resistance, and is widely applicable to equipment such as the main shaft of mining crushers, the frame rollers of metallurgical rolling mills, and the grinding rollers of cement vertical mills, ensuring stable operation under extreme conditions while reducing the frequency and cost of equipment maintenance through a convenient re-lubrication design.
