How to read the 22216 designation
| Segment | Meaning |
|---|---|
| 2 | Spherical roller bearing (double row, self-aligning) |
| 22 | Dimension series 22 |
| 16 | Bore code 16 → 80 mm bore. ISO bore code (00–03 = 10/12/15/17 mm; 04 and above = code × 5 mm). |
22216 interchange
22216 is an ISO designation: bore d, outside diameter D and width B are the same at each maker. The letters each maker adds are design and cage codes, not seal codes; K marks a tapered bore, and each maker marks the oil groove and holes in its own way. Send us the full number on your old bearing and we confirm the match.

Tolerances and fits for 22216
FULI makes 22216 to P0 as standard, with P6 on request. P0 is the Normal tolerance class of ISO 492; P6 limits are tighter. These are the P0 limits for the 80 × 140 × 33 mm size.
| Dimension | Nominal, mm | Deviation, µm | Limits, mm |
|---|---|---|---|
| Bore d (Δdmp) | 80 | 0 / −15 | 80.000 / 79.985 |
| Outside diameter D (ΔDmp) | 140 | 0 / −18 | 140.000 / 139.982 |
| Width B (ΔBs) | 33 | 0 / −150 | 33.000 / 32.850 |
Δdmp and ΔDmp: deviation of the mean bore and mean outside diameter in one radial plane. ΔBs: inner ring width; the outer ring width has the same limits.
Shaft and housing fits (general guidance)
For an inner ring that turns with a solid steel shaft under normal load, bearing makers’ fit tables give 80 m6 for the shaft of 22216. The housing bore is usually H7, or J7 where the outer ring must not creep.
| Seat | Deviation, µm | Limits, mm | Fit with 22216 |
|---|---|---|---|
| Shaft 80 m6 | +30 / +11 | 80.030 / 80.011 | 11 to 45 µm interference |
| Housing 140 H7 | +40 / 0 | 140.040 / 140.000 | 0 to 58 µm clearance |
| Housing 140 J7 | +26 / −14 | 140.026 / 139.986 | 14 µm interference to 44 µm clearance |
Taking the loosest and the tightest combination of limits, a P0 22216 on a 80 mm m6 shaft has 11 to 45 µm interference. Its outer ring has 0 to 58 µm clearance in an H7 bore and 14 µm interference to 44 µm clearance in a J7 bore.
This is general guidance, not a FULI specification. Heavy or shock loads, a hollow shaft, a thin-walled, split or light-alloy housing, or a large temperature difference between shaft and housing call for other classes, and the drawing of your machine takes priority. A tight shaft fit or a hot housing uses up internal clearance, and that is when C3 is chosen instead of C0.
If the outer ring turns and the shaft stands still, as in an idler pulley or a wheel hub, the fits are reversed: the housing gets the interference fit (for example N7 or P7) and the shaft a sliding one (g6 or h6).

22216 compared with nearby sizes
22216 measures 80 × 140 × 33 mm: bore d, outside diameter D and width B. Other spherical roller bearings on this site for the same 80 mm shaft are 22316 (80 × 170 × 58 mm).
22316 is the next heavier choice for a 80 mm shaft, with an outside diameter 30 mm larger (170 mm) and 25 mm more width (58 mm). In FULI's catalog 22316 has a dynamic load rating of 490 kN against 238 kN and a weight of about 6.60 kg against 2.10 kg for 22216.
In the 222 series the sizes either side of 22216 are 22215 for a 75 mm shaft and 22217 for a 85 mm shaft.

22216 weight, load ratings and speed
FULI's catalog gives the weight of 22216 as about 2.10 kg, so 100 bearings weigh about 210 kg and 1,000 about 2100 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
22216 has a dynamic load rating Cr of 238 kN and a static load rating C0r of 270 kN. Cr is the load used to work out rating life; C0r is the reference for loads carried while the bearing is stationary or turning slowly. The catalog lists two speed values, 4,300 and 6,000 rpm, without stating the lubrication for each column.

22216 bore and clearance versions
FULI's catalog lists 22216 in two bore versions on one line, both 80 × 140 × 33 mm: 22216W33 with a cylindrical bore and 22216K/W33 with a 1:12 tapered bore. W33 marks the lubrication groove and holes in the outer ring. The K version is mounted on an adapter sleeve, a withdrawal sleeve or a tapered shaft seat. Radial clearance is C0 as standard and C3 on request.
| Designation | What it is |
|---|---|
| 22216W33 | Cylindrical 80 mm bore, lubrication groove and holes, C0 clearance |
| 22216K/W33 | Tapered bore 1:12 for sleeve mounting, lubrication groove and holes |
| 22216W33 C3 | Cylindrical bore with C3 radial clearance |
| 22216K/W33 C3 | Tapered bore with C3 radial clearance |
22216 dimensions in inches
The nearest common inch shaft size to the 80 mm bore of 22216 is 3-1/8 in (79.38 mm), 0.62 mm smaller than the bore, so 22216 would be loose on it. Inch shafts need an inch bearing, not a metric one with a sleeve or shim.
| Dimension | Millimetres | Inches |
|---|---|---|
| Bore d | 80 mm | 3.1496 in |
| Outside diameter D | 140 mm | 5.5118 in |
| Width B | 33 mm | 1.2992 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Grease for 22216
Relubricating 22216 from the side takes about 23.1 g each time by the formula in our grease calculator: 0.005 × D × B = 0.005 × 140 × 33. 22216W33 has a lubrication groove and holes in the outer ring; when grease goes in through them the formula is 0.002 × D × B, about 9.24 g for 22216.
How FULI supplies 22216

FAQ
What is the difference between 22216 and 22316?
Both fit a 80 mm shaft. 22216 is 80 × 140 × 33 mm and 22316 is 80 × 170 × 58 mm, so 22316 has an outside diameter 30 mm larger (170 mm) and 25 mm more width (58 mm). In FULI's catalog 22316 has a dynamic load rating of 490 kN against 238 kN and a weight of about 6.60 kg against 2.10 kg for 22216. Choose 22316 for a higher load where the housing has room for it; 22216 keeps the housing smaller.
What size is 22216 in inches?
22216 is 3.1496 × 5.5118 × 1.2992 in (80 × 140 × 33 mm, d × D × B). The nearest common inch shaft size to the 80 mm bore of 22216 is 3-1/8 in (79.38 mm), 0.62 mm smaller than the bore, so 22216 would be loose on it. Use an inch bearing on an inch shaft.
How much does 22216 weigh?
About 2.10 kg in FULI's catalog, so 100 pieces weigh about 210 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
How much grease does 22216 need?
About 23.1 g each time it is relubricated from the side (0.005 × 140 × 33).
Is 22216 the same size across brands?
Bore d, outside diameter D and width B are the same: 22216 is an ISO designation. The letters each maker adds (SKF E or CC, NSK CE4, EAE4 or CDE4, NTN EAD1, Koyo RZ, NACHI EX or E, FAG E1-XL) are design and cage codes, not seal codes. K marks a tapered bore, and the oil groove and holes are marked differently by each maker (SKF W33, NSK E4, NTN D1).
