SKF22209CCJC4W33Spherical Roller Bearing – Straight Bore, 45 mm ID, 85 mm OD, 23 mm Width, Open, C4 Clearance, W33 Lubrication Groove

Product Description

What this part is: SKF 22209 CCJ/C4 W33 double-row spherical roller bearing, 45 x 85 x 23 mm. Manufacturer: SKF. Manufacturer Part Number: 22209CCJC4W33. Base Number: 22209. Series: 22200. Bearing Type: Spherical Roller Bearing. Number of Rows: 2. Rolling Elements: Spherical Rollers. Design Units: Metric. Bore: 45 mm. Outside Diameter: 85 mm. Overall Width: 23 mm. Bore Type: Straight. Closure Type: Open. Cage Type: Pressed steel, window. Cage Material: Steel. Bearing Material: Bearing Steel. Internal Clearance: C4. Precision Rating: ABEC 1 / P0. Maximum Permissible Misalignment: 2°. Unit Quantity: 1 Pc. Decoding the designation: 222 is the dimension series for a double-row spherical roller bearing. CC and CJ are cage and execution codes for a pressed steel window cage. C4 is the radial internal clearance group, wider than both CN and C3. W33 is the lubrication feature: an annular groove machined into the outer ring outside diameter with three radial holes drilled through to the roller path. The bore is cylindrical, so the bearing seats directly on the shaft. Searchable forms of the number are 22209CCJC4W33, 22209 CCJ/C4W33, 22209 CCJ C4 W33 and 22209 CC CJ C4 W33. What these specs mean in practice: Dynamic Load Rating: 104 kN / 23,400 lbf. Static Load Rating: 98 kN / 22,000 lbf. Limiting Speed: 7,500 rpm. Item Weight: 1.28 lb. Maximum Temperature: 200°C. Minimum Temperature: −30°C. Two rows of spherical rollers running in a common concave outer raceway carry high radial load and take thrust in both directions, and the roller set swivels within the outer ring, giving 2° of permissible shaft-to-housing misalignment without edge loading. The C4 clearance group leaves more room in the mounted bearing than CN or C3, which suits a heavy interference fit on the shaft, a hot inner ring, or a large temperature difference across the rings. Harmonization Code: 8482.30.00. Lubrication feature: Lubricant: Grease or oil. Relubrication: Yes, through the W33 provision. The groove distributes lubricant circumferentially around the outer ring and the three radial holes carry it inward to the rolling elements, so the roller path is fed from the outside diameter rather than through the ring faces. The same passages serve a grease gun, a single-point lubricator, a centralised grease line, a circulating-oil system or oil mist. Bore form and mounting: Bore Type: Straight. The 45 mm cylindrical bore mounts directly on the shaft journal, and the mounted clearance follows from the shaft and housing fits rather than from a drive-up measurement. Quantity and configuration: Unit Quantity: 1 Pc. One complete bearing: inner ring, two rows of rollers with their cages, and the outer ring with the W33 groove and holes. Interchange guidance: Cross-Reference 1: FAG 22209-E1-C4. Cross-Reference 2: NTN 22209C4. Cross-Reference 3: Timken 22209CJ-C4. All three are the same 45 x 85 x 23 mm envelope with a cylindrical bore and C4 clearance. Cage execution and load ratings differ between makers, so take the rating from the designation actually fitted. A CN or C3 bearing on this envelope is a related clearance rather than an interchange.
