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.

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

W64B — Solid Oil: the free space inside the bearing is filled with a polymer matrix saturated with lubricating oil.

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.

Solid Oil is a lubricant-saturated polymer that fills the space around the rollers and holds two to four times the oil volume of an equivalent grease charge. It stays put in wet, dusty and washdown environments and in positions where a relubrication line cannot be run. Lubricant: Solid Oil.

The W33 groove and its three radial holes take lubricant from the housing lubrication port straight into the roller path.

Cage Material: pressed steel. The CC window cages are light and tolerant of shock, which is what makes them the standard execution across mill, conveyor, fan and crusher work.

Quantity and configuration

Unit Quantity: 1 Pc.

Mounting data

Straight 80 mm bore, so the bearing presses directly onto the shaft seat. Housing bore 140 mm, seat length 33 mm. Fitting the bearing straight to the shaft sets the running clearance from the interference fit rather than from a taper.

Interchange guidance

80 x 140 x 33 mm is the ISO boundary size for a 22216, so equivalent 22216 executions from other makers share the envelope. Match the execution as well as the size: the tapered-bore 22216 CCK/W33 mounts on an adapter sleeve and needs a different shaft seat, and the SKF E design on the same envelope carries a different roller complement and different ratings.
