FAGDouble Row Spherical Roller Bearing 80 mm Taper Bore x 140 x 33 mm, Brass Cage, C3, W33

Product Description

What this part is

A FAG 22216-EAS-K-M-C3-W33 double-row spherical roller bearing: 80 mm tapered bore, 140 mm outside diameter, 33 mm wide, with a machined brass cage, C3 internal clearance and the W33 lubrication groove and holes. Bearing only. The mating adapter sleeve is the FAG H2316.

Decoding the designation

22216: double-row spherical roller, 222 dimension series, 80 mm bore. E: reinforced internal design, larger rollers and higher capacity than the base design. AS: lubrication groove in the outer ring with three radial holes, FAG’s code for the feature the industry writes as W33. K: 1:12 tapered bore. M: machined brass cage. C3: radial internal clearance greater than normal.

What these specifications mean in practice

A double-row spherical roller self-aligns, so it tolerates shaft deflection and housing misalignment that would destroy a cylindrical roller, and it takes thrust in both directions. The 1:12 tapered bore is a mounting system: the bearing is drawn up a matching taper on an adapter sleeve, and the drive-up distance sets the residual clearance, which is why C3 is specified. The machined brass cage runs cooler and takes more shock than a pressed-steel cage and raises the usable temperature ceiling. The W33 groove and its three radial holes take grease or oil from a housing port to the loaded zone. Mounted on an H2316 adapter sleeve, the sleeve’s own shaft seat is 70 mm; the sleeve’s tapered outside diameter matches the bearing’s 80 mm tapered bore.

Quantity and configuration

Unit Quantity: 1 Pc. Bearing only, as one complete non-separable assembly. The FAG H2316 adapter sleeve is a separate part number.

Interchange guidance

The ISO base number 22216-K identifies the 80x140x33 mm size with a 1:12 taper across brands: SKF 22216 EK, NSK 22216EAKE4, NTN 22216EAKD1 and Timken 22216KEMW33 are the same size, bore form and machined-brass cage class. FAG 22216-E1A-K-M-C3 and 22216-E1-XL-K-C3 are the same bearing in current FAG nomenclature. The FAG 22216-E-AS-M-C3 is the straight-bore form of the same bearing. A 22216 K with a pressed-steel CC or EJ cage, such as SKF 22216 CCK/W33 or Timken 22216KEJW33, is the same seat with a different cage and its own rating and speed limits.
