Decoding the designation

22216 — SKF’s number for the 222 dimension series, 80 x 140 x 33 mm.

CC — the standard SKF spherical roller execution: two window-type pressed steel cages running against an inner ring guide ring.

K — tapered bore, 1:12 taper.

W33 — an annular groove around the outer ring outside diameter with three radial feed holes into the roller path.

What these specs mean in practice

Two roller rows run on one spherical raceway ground into the outer ring, so the inner ring and roller assembly swivel inside the outer ring. Permissible Misalignment: 1.5° absorbs shaft deflection under load and out-of-line housing bores that would edge-load a cylindrical or deep groove bearing. Both rows share radial load and the type takes thrust in either direction.

Bore Type: tapered 1:12. Driving the bearing further up the taper spreads the inner ring and reduces the radial internal clearance, so the fit is set by measurement during mounting rather than by shaft tolerance alone. That is what lets a bearing this size run on plain drawn shafting or on a shaft that carries several bearings in line.

The W33 groove and its three radial holes take lubricant from the housing lubrication port straight into the roller path. Lubricant: grease or oil — the same passages serve a grease gun, a single-point lubricator or a circulating-oil feed.

Cage Material: pressed steel. The CC window cages are light and shock-tolerant, which is why they are the standard execution across mill, conveyor, fan and crusher duty.

Quantity and configuration

Unit Quantity: 1 Pc.

Mounting data

The 1:12 tapered bore seats on an adapter sleeve. Adapter Sleeve: H316, whose tapered outside diameter is 80 mm and whose shaft seat is 70 mm, secured with a KM 16 locknut and an MB 16 lockwasher. Housing bore 140 mm, seat length 33 mm. Clearance reduction is measured with a feeler gauge as the bearing is driven up the taper.

Interchange guidance

80 x 140 x 33 mm is the ISO boundary size for a 22216, so equivalent tapered-bore 22216 K executions from other makers share the envelope and the 1:12 taper. Match the bore form as well as the size: the straight-bore 22216 CC/W33 presses directly onto a 80 mm shaft seat and is a related size rather than a swap.
