SKF 23220 CC/W33 double-row spherical roller bearing. Brand: SKF. Designation: 23220 CC/W33. Base number: 23220. Bearing type: spherical roller bearing, double row, self-aligning. Bore form: cylindrical (straight) bore. Closure: open. GTIN: 7316576657184.
Bore d: 100 mm. Outside diameter D: 180 mm. Width B: 60.3 mm. Design units: metric. Mass: 6.6 kg. Number of rows: 2. Rolling elements: barrel (spherical) rollers.
Basic dynamic load rating C: 498 kN. Basic static load rating C0: 600 kN. Fatigue load limit Pu: 63 kN. Reference speed: 2,400 r/min. Limiting speed: 3,400 r/min. Radial internal clearance: Normal (CN). On a double-row spherical roller bearing the static rating stands above the dynamic rating as a matter of catalogue form for the family.
Series: 232 (ISO 23220), the wide high-capacity section. In the same 100 mm bore the 222-series 22220 is a narrower bearing of lower rating, and the two occupy different shaft and housing envelopes. The 232 section carries substantially more radial and shock load in the same bore.
23220: ISO base number for a 232-series double-row spherical roller bearing of 100 mm bore. CC: SKF execution with two pressed-steel window-type cages and a guide ring centred on a flangeless inner ring. W33: annular lubrication groove and three radial holes in the outer ring. The designation carries no K, so the bore is cylindrical and the bearing mounts directly on the shaft seat. The designation carries no clearance suffix, so radial internal clearance is Normal (CN).
Cage type: window-type, guided by a guide ring centred on a flangeless inner ring. Cage material: pressed steel. Bearing material: through-hardened bearing steel. The W33 groove and its three radial holes take lubricant from the housing lubrication port and distribute it circumferentially around the outer ring and inward to both roller rows.
Two rows of barrel rollers run on a single spherical raceway in the outer ring, so the inner ring and roller assembly swivel inside the outer ring. The bearing accommodates static misalignment from housing bore variation and dynamic misalignment from shaft deflection under load, while carrying heavy radial load with axial load in both directions.
Crushers and mills, vibrating screens, conveyor head and tail shafts, gearboxes, fans and blowers, pulp and paper machinery, mixers and agitators, and heavy plummer-block positions.
Same-envelope designations: SKF 23220 CCK/W33 (tapered bore, adapter-sleeve mounting), FAG 23220-E1A-M (machined brass cage), NTN 23220, NSK 23220CAM (machined cage), Timken 23220, MRC 23220 (legacy brand, now SKF). Unspaced and spaced listing forms: 23220CCW33 and 23220 CC W33. Match cage execution and clearance class when selecting among them.
