22228 CC/W33

The 22228 CC/W33 spherical roller bearing is engineered for demanding industrial applications where heavy loads, misalignment, and potential vibration are common challenges. This robust bearing features two rows of symmetrical rollers, a common spherical outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis. The CC designation indicates an optimized internal design with a high-capacity pressed steel cage, while the W33 feature signifies an annular groove and three lubrication holes in the outer ring, facilitating efficient grease or oil distribution. Choosing the 22228 CC/W33 model ensures superior reliability and longer service life for equipment such as heavy machinery, gearboxes, pumps, and fans operating in tough environments.

Designed to accommodate both heavy radial loads and axial loads in both directions, the 22228 CC/W33 bearing automatically self-aligns to compensate for static or dynamic shaft misalignment. Its standard dimensions are a 140 mm bore (d), 250 mm outside diameter (D), and 68 mm width (B). This specific bearing is highly sought after in sectors requiring continuous operation and minimal downtime, including mining, pulp and paper production, and large-scale construction. By combining the benefits of a high load rating and the W33 lubrication feature, the 22228 CC/W33 provides a cost-effective solution for reducing maintenance costs and improving the overall efficiency and uptime of critical rotating machinery.
