Spherical roller bearing 22234 CCK/W33 SKF 170x310x86

Self-aligning bearing for extremely heavy loads

Tapered bore CCK and W33 lubrication system

Reliable solution for heavy industrial applications

Main description

The 22234 CCK/W33 spherical roller bearing from SKF is a heavy-duty rolling bearing engineered for the most demanding industrial applications involving very high radial loads, significant axial loads, and shaft misalignment. With large dimensions 170x310x86, this bearing is widely used in heavy machinery, main drive systems, large gearboxes, and equipment operating under continuous and extreme conditions.

The spherical roller design provides excellent self-aligning capability, allowing the bearing to compensate for shaft deflection, mounting inaccuracies, and housing deformation. This is a major advantage compared to a standard ball bearing, which requires precise alignment and offers lower load capacity. The 22234 CCK/W33 bearing ensures stable and safe operation even under severe mechanical stress.

The CCK designation indicates a tapered bore (1:12), enabling mounting on adapter or withdrawal sleeves as well as directly on tapered shafts. This solution simplifies installation and removal while allowing accurate adjustment of internal clearance within the bearing unit. The W33 feature includes a lubrication groove and lubrication holes in the outer ring, enabling effective relubrication during operation and significantly improving high durability and service life.

The 22234 CCK/W33 SKF spherical roller bearing is commonly used in steel mills, mining equipment, cement plants, power generation, and other heavy industrial sectors. When installed in a robust bearing housing, it delivers excellent resistance to vibration, long service intervals, and reliable performance under continuous heavy loads.
