TorringtonDouble-Row Spherical Roller Bearing – 65 x 120 x 31 mm, 1:12 Tapered Bore, C3 Clearance, W33 Lubrication Groove

Product Description

What this part is: Torrington 22213KVJW33C3, a double-row spherical roller bearing. Bore: 65 mm. Outside Diameter: 120 mm. Overall Width: 31 mm. Bore Type: Tapered, 1:12 taper. Number Of Rows: 2. Rolling Elements: Spherical rollers. Cage Type: Pressed. Cage Material: Steel. Bearing Material: Chrome steel. Closure Type: Open. Internal Clearance: C3. Precision Rating: ABEC 1 / P0. Relubrication: W33 annular groove in the outer ring with three radial feed holes. Series: 22200. Country of Origin: Italy. Decoding the designation: Bore Type: K — a 1:12 tapered bore. Cage: J — pressed steel. Lubrication Feature: W33 — an annular groove machined around the outside diameter of the outer ring, with three radial holes drilled inward from it. Internal Clearance: C3 — greater than normal. Base Number: 22213. Bore form and adapter sleeve: Bore Type: Tapered, 1:12. Adapter Sleeve: H313. The sleeve’s tapered outside diameter matches the 65 mm bore of this bearing, and its cylindrical shaft seat is 60 mm, so an H313 mounts this bearing on a plain 60 mm shaft. The sleeve set is completed by a KM13 locknut and an MB13 lockwasher. Driving the bearing up the taper is also what sets the running clearance, so the C3 starting clearance gives room for that reduction while leaving working clearance in service. Load and speed data: Dynamic Load Rating: 206 kN (46,310 lbf). Static Load Rating: 216 kN (48,558 lbf). Limiting Speed: 5,100 rpm. Operating Temperature Range: −30 °C to +200 °C. A double-row spherical roller bearing carries very high radial load and takes thrust in both directions, and its two rows of barrel rollers run on a common spherical outer raceway, so the inner ring and roller assembly can swivel within the outer ring. That accommodates shaft deflection and housing misalignment without edge-loading the raceways, which is why this type sits under long shafts on fans, crushers, conveyors and gearboxes. Lubrication: Relubrication Feature: W33. Lubricant: Grease or oil. The annular groove around the outer-ring outside diameter takes lubricant from the housing supply and distributes it circumferentially, and the three radial holes carry it inward to the rolling elements. That feeds both rows from a single housing port, and it suits grease from a gun, a single-point lubricator or a centralised system, or oil from a circulating or oil-mist system. Quantity and configuration: Unit Quantity: 1 Pc. Item Weight: 3.52 lb. Harmonization Code: 8482.30.00.40. Related designations: Cross-Reference 1: SKF 22213 EK/C3. Cross-Reference 2: FAG 22213-E1-K-C3. Cross-Reference 3: NTN 22213BKD1C3. All three are 65 x 120 x 31 mm on a 1:12 tapered bore at C3 clearance. Cross-Reference 4: 22213 CC/W33 C3 — related size, straight bore instead of tapered, which mounts directly on a shaft rather than on an adapter sleeve.
