TORRINGTON22213VCFW33C3Spherical Roller Bearing – Straight Bore, 65 mm ID, 120 mm OD, 31 mm Width, Open, C3 Clearance, W33 Lubrication Groove

Product Description

What this part is

Torrington 22213VCFW33C3 double-row spherical roller bearing. Bore: 65 mm. Outside diameter: 120 mm. Width: 31 mm. Series: 222, ISO dimension series 22213. Bore form: straight. Closure: open both faces. Torrington is a Timken brand.

Decoding the designation

W33: annular lubrication groove in the outer ring with three radial feed holes. C3: internal clearance greater than normal. VCF: Torrington design designation, cross-referenced by Timken as 22213EJW33. The carton also carries 65SD22. Searchable forms include 22213VCFW33C3, 22213-VCF-W33-C3, 22213VCF and 22213.

What these specs mean in practice

Basic dynamic load rating: 148 kN (33,300 lbf). Basic static load rating: 183 kN (41,100 lbf). Speed limit: 7,000 rpm. Two rows of barrel rollers run on a common spherical outer raceway, so the bearing carries heavy radial load with thrust in both directions and self-aligns to shaft deflection and housing misalignment. On a double-row spherical roller the static rating sitting above the dynamic rating is the normal catalogue relationship. C3 clearance leaves more running clearance than the standard class, which suits a tight interference fit on the shaft or a hot-running application.

Lubrication provision

The W33 outer ring carries a circumferential groove and three radial holes, so grease or oil is fed directly to the rolling elements through the housing. That supports scheduled relubrication in service without dismounting.

Quantity and configuration

One bearing, two rows of rollers, straight bore. It mounts directly on the shaft.

Interchange guidance

Same-specification equivalents: Timken 22213EJW33C3, SKF 22213 E/C3, FAG 22213-E1-XL-C3, NSK 22213EAE4C3. A 22213K with a 1:12 tapered bore is a related size rather than an interchange, because it mounts on an adapter sleeve instead of directly on the shaft.
