This is an SKF 22236 CCK/W33 double-row spherical roller bearing, stamped "22236CCK" with "SKF" and "USA" visible on the inner ring face (older domestic SKF production, generally regarded as premium over import stock). Spherical roller bearings carry very high radial loads plus axial loads in both directions and are self-aligning, meaning they tolerate shaft deflection and housing misalignment without losing service life. That makes them a workhorse in heavy rotating equipment: crushers, vibrating screens, large gearboxes, fans, pumps, conveyors, and paper machinery. Your tape measurements confirm the published geometry: 7.087 inch (180 mm) bore, 12.598 inch (320 mm) outside diameter, and 3.386 inch (86 mm) width.

The designation breaks down cleanly. "222" is the spherical roller bearing type in the wide 22 dimension series, "36" is the bore code (36 x 5 = 180 mm), "CC" is SKF's standard Explorer-class design with a sheet-steel cage and optimized roller guidance, "K" denotes the 1:12 tapered bore (mounted on an adapter or withdrawal sleeve, or a tapered shaft seat), and "W33" is the annular groove with three lubrication holes in the outer ring for re-lubrication in service. The unit rates at 1237 kN dynamic and 1560 kN static load capacity with a 2600 rpm limiting speed, and weighs roughly 64 lb (29 kg).
