Maximum Permissible Misalignment: 2°. Country of Origin: France.

Decoding the designation

22211 is the ISO 222 dimension series at a 55 mm bore. CC is the pressed steel cage with an inner-ring guide ring. K gives Bore Type: Tapered 1:12, which mounts on an adapter sleeve rather than directly on a plain shaft. No clearance suffix is carried, so Internal Clearance: CN, the normal group. The carton also reads 22211 C K J and 22211 C K, both the same bearing.

What these specs mean in practice

Dynamic Load Rating: 129 kN / 29,000 lbf. Static Load Rating: 127 kN / 28,551 lbf. Limiting Speed: 6,300 rpm. Maximum Operating Temperature: 200 °C. Minimum Operating Temperature: -30 °C. Item Weight: 1.84 lb. Harmonization Code: 8482.30.00. Two rows of barrel rollers run on a common spherical outer raceway, so the inner ring and roller set swivel inside the outer ring and take up to 2° of shaft-to-housing misalignment while carrying full load. Thrust is carried in both directions. The pressed steel cage keeps rotating mass low and leaves large lubricant paths between the rollers.

Quantity and configuration

Unit Quantity: 1 Pc. One bearing ships. Carton and cross designations, all recorded as search terms: 22211CCK, 22211 CC K, 22211-CC-K, 22211CKJ, 22211 C K J, 22211CK, 22211 C K.

Fitting notes

Adapter Sleeve: SKF H311. The sleeve’s tapered outside diameter is 55 mm to match this bore, and its bore seats a 50 mm shaft. An H311 takes a KM11 locknut and an MB11 lockwasher. Drive-up on the taper sets the mounted radial internal clearance, so the CN figure is the as-delivered clearance before mounting.

Interchange guidance

Direct equivalents on the 55 x 100 x 25 mm tapered-bore envelope: FAG 22211-E1-K, NTN 22211EAKD1, Timken 22211K, NSK 22211EAKE4. A 22211 CC without the K is a related size on a straight bore, mounting directly on the shaft with no sleeve. A 22211 CCK/W33 is a related size carrying an outer-ring lubrication groove and three radial feed holes.
