Decoding the designation

22213 is the 222 spherical roller series at a 65 mm bore. The C-prefixed cage code is SKF’s pressed steel window cage. W33 is an annular groove machined into the outer ring outside diameter with three radial holes through to the rolling elements. No K appears, so the bore is cylindrical. No clearance suffix appears, so the bearing is supplied to normal radial internal clearance. Written as 22213-CJ-W33-W64B, 22213CJW33W64B and 22213 CC/W33.

What these specs mean in practice

Two rows of barrel-shaped rollers run on a common spherical outer raceway, so the inner ring and roller set swivel inside the outer ring. That absorbs shaft deflection and housing misalignment without loading the roller ends, and it carries heavy radial load together with thrust in both directions. The W33 groove distributes lubricant circumferentially around the outer ring and the three radial holes carry it inward to the rolling elements; the same passages take grease from a gun, a single-point lubricator or a centralised system, and equally take circulating oil or oil mist. Groove width: 6 mm. Lubrication hole diameter: 3 mm.

Quantity and configuration

Unit Quantity: 1 Pc. One bearing per sale unit, open on both faces.

Mounting data

The cylindrical bore seats directly on a 65 mm shaft journal with an interference fit. Shaft abutment diameter: 74 mm minimum. Housing abutment diameter: 111 mm maximum. Shaft and housing fillet radius: 1.5 mm maximum. Bearing chamfer r1,2: 1.5 mm minimum. The W33 groove aligns with the lubrication port in the housing.

Interchange guidance

22213 is an ISO-pattern designation and the W33 lubrication feature carries its own code on every maker. Cross-Reference 1: FAG 22213-E1. Cross-Reference 2: NSK 22213EAE4. Cross-Reference 3: NTN 22213. Cross-Reference 4: Koyo 22213RW33. Cross-Reference 5: Timken 22213EJW33. Cross-Reference 6: Torrington 22213CJW33. On NSK the E4 suffix is the same groove-and-three-holes feature as SKF’s W33. Searchable forms: 22213-CJ-W33-W64B, 22213CJW33W64B, 22213CCW33, 22213.
