Decoding the designation

22216 is the 222 spherical roller series at an 80 mm bore. CC is SKF’s pressed steel window cage, guided on the inner ring. K is a 1:12 tapered bore. C3 is radial internal clearance greater than normal. Written as 22216-CCK-C3, 22216-CC-K-C3, 22216CCKC3 and 22216K.

What these specs mean in practice

Two rows of barrel-shaped rollers run on a common spherical outer raceway, so the inner ring and roller set swivel inside the outer ring. That takes up shaft deflection and housing misalignment without loading the roller ends, and it carries heavy radial load plus thrust in both directions. C3 clearance is the normal choice on a tapered-bore spherical roller, because driving the inner ring up the sleeve taper is itself what sets the final running clearance — starting from C3 leaves room for that drive-up.

Quantity and configuration

Unit Quantity: 1 Pc. One bearing per sale unit, open on both faces.

Mounting data

The 1:12 tapered bore mounts on an H316 adapter sleeve, whose tapered outside diameter is 80 mm to match this bore and whose parallel bore takes a 70 mm shaft. The sleeve is secured with a KM 16 lock nut and an MB 16 lock washer. Shaft abutment diameter: 91 mm minimum. Housing abutment diameter: 129 mm maximum. Shaft and housing fillet radius: 2 mm maximum. Bearing chamfer r1,2: 2 mm minimum.
