22217 cross reference by brand
22217 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. The table below lists the checked forms.

Tolerances and fits for 22217
FULI makes 22217 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 85 × 150 × 36 mm size.
| Dimension | Nominal, mm | Deviation, µm | Limits, mm |
|---|---|---|---|
| Bore d (Δdmp) | 85 | 0 / −20 | 85.000 / 84.980 |
| Outside diameter D (ΔDmp) | 150 | 0 / −18 | 150.000 / 149.982 |
| Width B (ΔBs) | 36 | 0 / −200 | 36.000 / 35.800 |
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 85 m6 for the shaft of 22217. The housing bore is usually H7, or J7 where the outer ring must not creep.
| Seat | Deviation, µm | Limits, mm | Fit with 22217 |
|---|---|---|---|
| Shaft 85 m6 | +35 / +13 | 85.035 / 85.013 | 13 to 55 µm interference |
| Housing 150 H7 | +40 / 0 | 150.040 / 150.000 | 0 to 58 µm clearance |
| Housing 150 J7 | +26 / −14 | 150.026 / 149.986 | 14 µm interference to 44 µm clearance |
Taking the loosest and the tightest combination of limits, a P0 22217 on a 85 mm m6 shaft has 13 to 55 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).

22217 compared with nearby sizes
22217 measures 85 × 150 × 36 mm: bore d, outside diameter D and width B.
22314 has the same 150 mm outside diameter with a 70 mm bore, so it fits the same housing bore on a smaller shaft.
In the 222 series the sizes either side of 22217 are 22216 for a 80 mm shaft and 22218 for a 90 mm shaft.

22217 weight, load ratings and speed
FULI's catalog gives the weight of 22217 as about 2.66 kg, so 100 bearings weigh about 266 kg and 1,000 about 2660 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
22217 has a dynamic load rating Cr of 285 kN and a static load rating C0r of 325 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, 4,000 and 5,600 rpm, without stating the lubrication for each column.

22217 bore and clearance versions
FULI's catalog lists 22217 in two bore versions on one line, both 85 × 150 × 36 mm: 22217W33 with a cylindrical bore and 22217K/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 |
|---|---|
| 22217W33 | Cylindrical 85 mm bore, lubrication groove and holes, C0 clearance |
| 22217K/W33 | Tapered bore 1:12 for sleeve mounting, lubrication groove and holes |
| 22217W33 C3 | Cylindrical bore with C3 radial clearance |
| 22217K/W33 C3 | Tapered bore with C3 radial clearance |
22217 dimensions in inches
The nearest common inch shaft size to the 85 mm bore of 22217 is 3-3/8 in (85.73 mm), 0.73 mm larger than the bore, so 22217 will not go on it. Inch shafts need an inch bearing, not a metric one with a sleeve or shim.
| Dimension | Millimetres | Inches |
|---|---|---|
| Bore d | 85 mm | 3.3465 in |
| Outside diameter D | 150 mm | 5.9055 in |
| Width B | 36 mm | 1.4173 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Grease for 22217
Relubricating 22217 from the side takes about 27.0 g each time by the formula in our grease calculator: 0.005 × D × B = 0.005 × 150 × 36. 22217W33 has a lubrication groove and holes in the outer ring; when grease goes in through them the formula is 0.002 × D × B, about 10.8 g for 22217.
How FULI supplies 22217
The standard 22217 from FULI has GCr15 chrome steel rings and rollers, P0 precision and C0 radial clearance, with P6 and C3 on request.
Rings are marked with a brand you are authorised to use, with the FULI brand, or left neutral, as your order states. The box is printed with the model, precision class and brand.
Inquiries that leave out the prefix or suffix letters are the usual cause of a wrong quote, so write the full designation, for example 22217K/W33 C3.

FAQ
What size is 22217 in inches?
22217 is 3.3465 × 5.9055 × 1.4173 in (85 × 150 × 36 mm, d × D × B). The nearest common inch shaft size to the 85 mm bore of 22217 is 3-3/8 in (85.73 mm), 0.73 mm larger than the bore, so 22217 will not go on it. Use an inch bearing on an inch shaft.
How much does 22217 weigh?
About 2.66 kg in FULI's catalog, so 100 pieces weigh about 266 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
How much grease does 22217 need?
About 27.0 g each time it is relubricated from the side (0.005 × 150 × 36).
Is 22217 the same size across brands?
Bore d, outside diameter D and width B are the same: 22217 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).
