| Manufacturer Status | SKF; the C design has been superseded by the current E generation |
| Precision Class | ISO normal (ABEC 1 / P0) |
| Additional Attributes | Non-separable assembly. Pressed BRASS cage, not steel - the Y suffix is what says so, and it is easy to miss next to the far more common steel-caged CC and CJ. Spherical outer raceway gives static self-alignment; permissible misalignment 1.5 degrees. Takes axial load in both directions; keep Fa/Fr below e = 0.22. Abutment: da min 84 mm, Da max 121 mm. |

An SKF 22215 C.Y.W33 double-row spherical roller bearing. Bore: 75 mm. Outside Diameter: 130 mm. Width: 31 mm. Bore Type: Straight cylindrical. Closure Type: Open, both sides. Cage Material: Pressed brass. Cage Type: Window-type, centred on the inner ring. Internal Clearance: Normal (CN). Unit Quantity: 1 Pc. Spherical roller bearings carry very high radial load together with axial load in both directions, and the spherical outer raceway lets the inner-ring assembly swivel so the bearing self-aligns to shaft deflection or housing misalignment.
222: Double-row spherical roller bearing, ISO dimension series 22. 15: Bore code, 15 x 5 = 75 mm bore. C: SKF internal design with optimised internal geometry and a guide ring between the roller rows in place of a fixed central rib. Y: Pressed brass window-type cage, centred on the inner ring. W33: Circumferential lubrication groove around the outer ring outside diameter plus three radial lubrication holes through to the raceway. Bore Form: Straight cylindrical. Clearance Class: Normal (CN).
Bore d: 75 mm. Outside Diameter D: 130 mm. Width B: 31 mm. Chamfer rs min: 1.5 mm. Fillet ra max: 1.5 mm. Shaft Abutment da min: 84 mm. Housing Abutment Da max: 121 mm. Inner Ring Shoulder d1: 88 mm. Outer Ring Shoulder D1: 118 mm. Number of Rows: 2. Permissible Angular Misalignment: 1.5°. Precision Class: ISO normal (ABEC 1 / P0). Locking Method: Interference fit on a cylindrical shaft seat.
Cage Material: Pressed brass. Cage Type: Window-type, centred on the inner ring. Pressed brass sits between stamped steel and fully machined brass: more shock- and heat-tolerant than a steel cage and better behaved under marginal lubrication, lighter and less costly than a machined solid brass cage. A window-type pocket holds each roller on all four sides, so the rollers stay square under acceleration. The C design places a guide ring between the roller rows in place of a fixed central rib, so the full 31 mm of width goes into roller length, and that is the source of the load capacity.
Relubrication Feature: W33. Groove Width: 7 mm. Lubrication Hole Diameter: 3.5 mm. Number of Holes: 3. 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.
Axial Load Factor e: 0.22. Y1: 3.14. Y2: 4.67. Y0: 3.07. Limiting Speed: 5600 rpm. Operating Temperature Range: -40°C to 200°C. Bearing Material: Through-hardened bearing steel. Rolling Elements: Spherical rollers, two rows, with a guide ring in place of a central rib. Item Weight: 3.42 lbs. Harmonization Code: 8482.30.
Complete non-separable bearing: inner ring, two rows of spherical rollers, pressed brass window cage, guide ring, and outer ring carrying the lubrication groove and three holes. Condition: New old stock. Unit Quantity: 1 Pc.
Base Number: 22215. The 75 x 130 x 31 mm 222-series envelope is an industry standard, so a 22215 in another manufacturer’s nomenclature occupies the same seat, with cage construction as the differentiator. Same envelope with a machined brass cage: SKF 22215 CA/W33, FAG 22215-E1A-M and 22215 EAS.M, NSK 22215 CAME4, NTN 22215 EMW33, Timken 22215 EMW33, Koyo 22215RW33. Same envelope with a steel cage: SKF 22215 CC/W33 and 22215 CJ/W33, SKF 22215 E/W33, FAG 22215-E1 and 22215 ES.TVPB.W33, NSK 22215 CDE4, NTN and NTN-SNR 22215 EAW33, Timken 22215 EJW33, Koyo 22215RHW33, RHP 22215 EJW33. Tapered-Bore Counterpart: 22215 CYK/W33, 1:12 tapered bore, mounts on an H315 adapter sleeve for a 65 mm shaft. Manufacturer Status: SKF; the C design has been superseded by the current E generation. MPN Variants: 22215-CY-W33; 22215CY/W33; 22215CYW33; 22215 CY W33; 22215-C-Y-W33; 22215CY.
