FAG22216ESKTVPBW33Double-Row Spherical Roller Bearing 80 x 140 x 33 mm, 1:12 Tapered Bore, H316 Adapter Sleeve Mount on a 70 mm Shaft, Polyamide Cage, W33 Lubrication Groove, 1 Pc

Product Description

What this part is

A double-row spherical roller bearing, 80 mm bore x 140 mm outside diameter x 33 mm wide, in the ISO 222 dimension series, with a tapered bore. Two rows of barrel rollers share one spherical outer raceway, so the inner ring and roller set swivel bodily inside the outer ring. That self-aligning action absorbs shaft deflection and housing misalignment that would destroy a cylindrical roller or deep groove ball bearing of the same size, while carrying very heavy radial load and thrust in both directions.

Decoding the designation

222 — double-row spherical roller bearing, dimension series 22.
16 — bore code for an 80 mm bore.
E — Schaeffler’s increased-capacity internal design, using longer symmetrical barrel rollers. The current code for this design family is E1.
S — annular lubrication groove around the outer ring plus lubrication holes through it. This is FAG’s own code for the feature the rest of the industry writes as W33, which is why both forms are carried on this listing.
K — tapered bore, taper ratio 1:12. The character that decides how the bearing mounts.
TVPB — one-piece moulded window cage in glass-fibre reinforced polyamide, guided on the inner ring.

There is no clearance suffix, so the bearing carries Normal (CN) radial internal clearance.

What these specs mean in practice — the tapered bore:
A 1:12 tapered bore will not fit a plain shaft. It has to be drawn up a matching taper, which means one of two accessories, neither of which is included with this bearing:

An H316 adapter sleeve, letting the bearing clamp anywhere along a plain 70 mm shaft. That figure surprises people, and it is the worst trap in the whole adapter-sleeve range: for sleeves up to H313 the shaft is the bearing bore minus 5 mm, but from H314 upwards the step is 10 mm. So an 80 mm bore bearing sits on a 70 mm shaft here, not 75 mm. Order on the bearing bore, not on a guess. H-series adapter sleeves are normally supplied complete with their KM16 locknut and MB16 lockwasher.
An AH316 withdrawal sleeve is the alternative, and it does not share the quirk — withdrawal sleeves run bore minus 5 mm throughout, so AH316 fits a 75 mm seat. Do not cross-populate those two numbers. Withdrawal sleeves come without a nut, ordered separately.

What the taper buys you is direct control of internal clearance and the freedom to mount a bearing anywhere along a length of plain round bar with no machined seat. How far you draw the bearing up the sleeve sets how much the inner ring expands and therefore what running clearance you finish with. Measure the clearance reduction as you tighten: over-driving preloads the bearing before it ever turns and is the classic commissioning failure, and under-driving lets the inner ring creep on the sleeve.

What these specs mean in practice — the polyamide cage:
The TVPB cage is the other spec that decides whether this bearing suits your machine. Glass-fibre reinforced polyamide is light, quiet, low-friction and forgiving of brief lubricant starvation, because the polymer has some dry-running tolerance of its own. The trade-off is temperature: continuous service is limited to roughly 120 °C, against about 200 °C for a pressed steel or machined brass cage. That ceiling is real, it is what you are buying or avoiding, and it is the operative limit on this bearing rather than any speed figure. Polyamide ages and embrittles above it, and aggressive EP additive packages and some synthetic oils accelerate that at elevated temperature. For a hot housing, a steam-cleaned machine or heavy shock duty, choose the steel or brass cage version instead.

The outer-ring groove and holes let grease or oil be fed straight into the roller rows through the housing. On an 80 mm bore bearing the grease volume is large and the relubrication interval short under load, so this matters — provided the housing has a lubrication port aligned to the groove.

Published ratings and mounting data

Schaeffler publishes the following for the 22216-E1-XL-K, the current-production form of this design:

Basic dynamic load rating C: 250 kN
Basic static load rating C0: 270 kN
Fatigue limit load Cu: 33.5 kN
Limiting speed: 6 200 rpm
Reference speed: 3 550 rpm
Mass: approximately 2.08 kg
Adapter sleeve: H316, for a 70 mm shaft
Withdrawal sleeve: AH316, for a 75 mm seat

With a polyamide cage the practical constraint is thermal, not kinematic: the 120 °C continuous cage temperature will be reached long before those speed figures become the limiting factor.

Quantity and configuration

Sold as 1 Pc. One complete bearing: inner ring with both roller rows and the polyamide cage, plus the outer ring. Spherical roller bearings are a non-separable assembly, so there is no cup or cone to buy alongside. This is the bare bearing only — no adapter sleeve, withdrawal sleeve, locknut, lockwasher or housing is included, and a sleeve is required to mount it.

Fitting notes

Slide the sleeve onto the shaft, fit the bearing onto the sleeve taper, then draw it up with the locknut while measuring the reduction in radial internal clearance with a feeler gauge across the unloaded roller row. Work to the published clearance-reduction figure rather than a torque setting, because the taper turns small axial travel into large radial expansion. Never drive through the rollers or the cage — a polyamide cage will not survive being hammered — and if you warm the bearing at all, keep it below about 120 °C, because the cage sets the ceiling here and not the steel. Bend one lockwasher tab into the nut slot when you are satisfied. Seat the outer ring squarely and let it take up its own alignment before final tightening. Align the housing lubrication port with the outer-ring groove and purge before the first run. A plain shaft seat at h9 is generally adequate under an adapter sleeve.

Interchange guidance

Dimensionally equivalent tapered-bore 22216 bearings include FAG 22216-E1-XL-K, SKF 22216 EK, NSK 22216EAKE4, NTN 22216EAKW33, NTN-SNR 22216EAKW33, Timken 22216KEJW33, RHP 22216EKJW33 and Link-Belt 22216LBK. All of them mount on the same H316 adapter sleeve, because H-series sleeve dimensions follow ISO 2982-1 and DIN 5415 rather than any one maker’s standard, so sleeves interchange freely across brands. Almost all of those alternatives carry a pressed steel or machined brass cage rather than polyamide, which raises the temperature ceiling from about 120 °C to about 200 °C — usually an upgrade, but worth knowing if the machine was specified for a low-friction polymer cage. The lubrication codes are one feature under different letters: S on FAG, W33 on SKF, Timken, RHP and Link-Belt, E4 on NSK, D1 on NTN Japan, B33 on legacy SNR. The straight-bore 22216 is a related size, not an interchange: same envelope, but it mounts directly on an 80 mm shaft and this bearing will not.
