FAG22216ESKTVPBSpherical Roller Bearing 80 x 140 x 33 mm, Double Row, 1:12 Taper Bore, W33 Lubrication Groove, Polyamide Cage

Product Description

What this part is

A FAG 22216-ES-K-TVPB-W33 double-row spherical roller bearing, 80 mm bore, 140 mm outside diameter, 33 mm wide, with a 1:12 tapered bore. Two rows of barrel rollers run on a single spherical outer raceway, so the inner ring, rollers and cage swivel bodily inside the outer ring. The bearing takes heavy radial load, thrust in both axial directions, and shaft-to-housing misalignment without edge-loading the rollers.

Decoding the designation

222 is the ISO dimension series of the double-row spherical roller family and 16 is the bore code, giving 80 mm at five millimetres per unit. E is the reinforced internal design with larger rollers. S is the FAG code for the lubrication groove and three radial feed holes in the outer ring, the feature that the ISO suffix W33 also denotes. K sets the bore taper at 1:12. TVPB is the glass-fibre reinforced polyamide cage.

Bore form and mounting hardware

The 1:12 taper bore mounts on an adapter sleeve, which is what lets the bearing be clamped anywhere along a plain cylindrical shaft rather than against a machined step. The sleeve for a 22216K is an H2316, and its shaft seat is 70 mm — one bore-code step below the bearing bore — supplied with a KM16 locknut and an MB16 lockwasher. Adapter sleeve H2316 is not included with this bearing. Driving the bearing further up the sleeve taper expands the inner ring and reduces radial internal clearance, so the mounted clearance is set by drive-up distance rather than by shaft tolerance.

What these specs mean in practice

The W33 groove delivers grease or circulating oil to the centre of the roller path through the housing rather than relying on migration from the ring faces, which is what makes the variant relubricatable on slow, heavily loaded, continuously running shafts. The polyamide cage runs quietly, tolerates shock and brief lubricant interruption, and has a practical continuous ceiling of 120 °C; the brass-caged E1A equivalent is the path above that.

Quantity and configuration

1 Pc. Bearing only, open on both faces, no seals and no shields. Supplied without adapter sleeve H2316, without locknut and without lockwasher.

Interchange guidance

The ISO base number is 22216K, so another maker’s 22216 EK W33 or 22216 CCK/W33 taper-bore double-row spherical roller of the same 33 mm width is a genuine interchange. The plain 22216-E-TVPB-W33 carried on this listing as a cross-designation is the straight-bore form and is a related size, not a substitution — it seats directly on the shaft and uses no sleeve. The 22216-E1A-K-TVPB-W33 changes the cage to brass, and 21316K shares the 80 mm bore in a narrower section.
