FAG22216ESK.TVPB.C3Double Row Spherical Roller Bearing – 1:12 Tapered Bore, 80 mm ID, 140 mm OD, 33 mm Width, Open, W33 Lube Groove, Polyamide Cage, C3 Clearance

Product Description

What this part is:

FAG 22216ESK.TVPB.C3 double row spherical roller bearing, 80 mm bore, 140 mm outside diameter, 33 mm width. Tapered 1:12 bore, open, two rows of symmetrical barrel rollers on a common concave sphered outer raceway, one-piece glass-fibre reinforced polyamide window cage, C3 radial internal clearance, W33 lubrication features in the outer ring.

Decoding the designation:

22216 gives the 222 dimension series and bore code 16 for the 80 mm bore. ES, written E1 in current FAG style, is the reinforced enhanced capacity execution. K is the 1:12 tapered bore. TVPB is the glass-fibre reinforced polyamide cage. C3 is clearance greater than normal. W33 is a lubrication groove in the outer ring with three radial feed holes.

What these specs mean in practice:

The sphered outer raceway lets the roller set swivel, so the bearing compensates alignment error and shaft deflection with almost no rise in friction or temperature. Two rows of rollers carry very high radial load and take thrust in both directions. Dynamic load rating 240 kN, static load rating 255 kN, limiting speed 4,800 rpm. The polyamide cage is light and quiet with low friction; it sets a practical continuous temperature ceiling near 120 °C, well below what a brass or steel cage would allow. W33 lets grease be fed through the housing straight to the rollers, so the bearing can be relubricated in place.

Bore form:

The bore is tapered 1:12, so the 80 mm figure is the bore at the large end rather than the shaft diameter. The bearing seats on an H2316 adapter sleeve, which fits a 70 mm straight shaft and is retained by a KM 16 locknut and MB 16 lockwasher. Those are separate related parts. It also mounts directly on a shaft journal machined to a 1:12 taper.

Quantity and configuration:

One bearing.

Fitting notes:

Radial clearance is set by drive-up on the adapter sleeve and measured with a feeler gauge as residual clearance, with the C3 starting value as the reference. Housing lubrication holes are aligned with the W33 groove at assembly so the feed path stays open.

Interchange guidance:

Same-design equivalents at 80 x 140 x 33 mm with a tapered bore and C3 clearance are the SKF 22216 EK/C3, NSK 22216EAKE4C3 and Timken 22216EJW33KC3. A 22216ES.TVPB.C3 without the K shares the envelope but has a straight bore and mounts directly on the shaft, making it a related size rather than an interchange.
