SKF22215 CY/W33Double-Row Spherical Roller Bearing, 75 x 130 x 31 mm, Straight Bore, Pressed Brass Window Cage, W33 Lubrication, Normal Clearance

Product Description

What this part is:

SKF 22215 CY/W33 is a double-row spherical roller bearing. Bore Diameter: 75 mm. Outside Diameter: 130 mm. Width: 31 mm. Bore Type: Straight cylindrical. Closure Type: Open, both sides. Internal Clearance: Normal (CN). Unit Quantity: 1 Pc. The spherical outer raceway lets the inner-ring assembly swivel, so the bearing carries heavy radial load with axial load in both directions and self-aligns to shaft deflection or housing misalignment.

Decoding the designation:

222 — double-row spherical roller bearing, ISO dimension series 22.

15 — bore code, 15 x 5 = 75 mm bore.

C — SKF internal design with 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 in the outer ring outside diameter plus three radial lubrication holes through to the raceway.

No K — straight cylindrical bore. No clearance suffix — normal (CN) radial internal clearance.
