A spherical roller bearing runs two rows of rollers against a spherical raceway in the outer ring. That geometry lets it carry heavy radial loads plus thrust in either direction while absorbing misalignment from shaft deflection or mounting error. Typical applications are belt drives, conveyors, fans, pumps, gearboxes, mills and machines that run with vibration.

The part number shows series and size. In NSK 22205CE4, 222 is the series and 05 is the size code; multiply it by 5 to get a 25 mm bore. SKF 21305 CC belongs to the 213 series and also has a 25 mm bore. A K marks a tapered bore, as in FAG 20205-K-TVP-C3, and C3 means internal clearance above normal. On NTN part numbers, W33 indicates a lubrication groove and holes in the outer ring. Internal designs carry brand-specific letters (CC, EA, CD), so copy the part number in full.

Start selection from load, speed, lubrication and operating temperature. Tapered bore versions go on an adapter sleeve or a withdrawal sleeve, which helps on long shafts or shafts with no shoulder. Pick the internal clearance from the fit and the temperature difference between the rings: a tighter fit or a bigger temperature gap calls for more clearance. Cage and internal design follow from speed and vibration levels.

Brands we carry in this line: SKF, FAG, NTN, NSK, Link-Belt, Timken, Sealmaster, Rexnord and McGill. Send the full part number, or the bore, outside diameter and width, and tell us whether the bore is cylindrical or tapered. A photo or another brand's part number works too; we'll cross-reference it. Reach us by WhatsApp or email and we'll quote promptly.

Dimensions and tolerances: Message us the part number on WhatsApp and we'll verify its dimensions and version with the manufacturer's datasheet.
