SKF 22217 CCK C3W33 Spherical Roller Bearings

SKF 22217 CCK/C3W33 is a robust double-row spherical roller bearing engineered to carry heavy radial loads while tolerating shaft misalignment in large, demanding machinery. The bearing’s bore is 85 mm, the outer diameter 150 mm, and the overall width 36 mm; it carries radial clearance class C3—greater than normal—to accommodate mounting tolerances and thermal expansion. As a two-row design, it uses two rows of barrel-shaped rollers between a spherical outer race and a concave inner race, providing stable rotation under substantial load and misalignment in applications like gearboxes, conveyors, crushers, and other heavy industrial equipment. The model designation 22217 CCK/C3W33 identifies a specific SKF configuration within its spherical roller bearing family, differentiating it from other variants and helping engineers specify the exact form required for compatible housings and mounting arrangements. For best results, ensure correct lubrication and mating housing that meet SKF guidelines for spherical roller bearings.
