22209 cross reference by brand
22209 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 22209
FULI makes 22209 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 45 × 85 × 23 mm size.
| Dimension | Nominal, mm | Deviation, µm | Limits, mm |
|---|---|---|---|
| Bore d (Δdmp) | 45 | 0 / −12 | 45.000 / 44.988 |
| Outside diameter D (ΔDmp) | 85 | 0 / −15 | 85.000 / 84.985 |
| Width B (ΔBs) | 23 | 0 / −120 | 23.000 / 22.880 |
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 45 m5 for the shaft of 22209. The housing bore is usually H7, or J7 where the outer ring must not creep.
| Seat | Deviation, µm | Limits, mm | Fit with 22209 |
|---|---|---|---|
| Shaft 45 m5 | +20 / +9 | 45.020 / 45.009 | 9 to 32 µm interference |
| Housing 85 H7 | +35 / 0 | 85.035 / 85.000 | 0 to 50 µm clearance |
| Housing 85 J7 | +22 / −13 | 85.022 / 84.987 | 13 µm interference to 37 µm clearance |
Taking the loosest and the tightest combination of limits, a P0 22209 on a 45 mm m5 shaft has 9 to 32 µm interference. Its outer ring has 0 to 50 µm clearance in an H7 bore and 13 µm interference to 37 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).

22209 compared with nearby sizes
22209 measures 45 × 85 × 23 mm: bore d, outside diameter D and width B. Other spherical roller bearings on this site for the same 45 mm shaft are 22309 (45 × 100 × 36 mm).
22309 is the next heavier choice for a 45 mm shaft, with an outside diameter 15 mm larger (100 mm) and 13 mm more width (36 mm). In FULI's catalog 22309 has a dynamic load rating of 183 kN against 102 kN and a weight of about 1.40 kg against 0.59 kg for 22209.
In the 222 series the sizes either side of 22209 are 22208 for a 40 mm shaft and 22210 for a 50 mm shaft.

22209 weight, load ratings and speed
FULI's catalog gives the weight of 22209 as about 0.59 kg, so 100 bearings weigh about 59 kg and 1,000 about 590 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
22209 has a dynamic load rating Cr of 102 kN and a static load rating C0r of 98 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, 7,500 and 10,000 rpm, without stating the lubrication for each column.

22209 bore and clearance versions
FULI's catalog lists 22209 in two bore versions on one line, both 45 × 85 × 23 mm: 22209W33 with a cylindrical bore and 22209K/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 |
|---|---|
| 22209W33 | Cylindrical 45 mm bore, lubrication groove and holes, C0 clearance |
| 22209K/W33 | Tapered bore 1:12 for sleeve mounting, lubrication groove and holes |
| 22209W33 C3 | Cylindrical bore with C3 radial clearance |
| 22209K/W33 C3 | Tapered bore with C3 radial clearance |
22209 dimensions in inches
The nearest common inch shaft size to the 45 mm bore of 22209 is 1-3/4 in (44.45 mm), 0.55 mm smaller than the bore, so 22209 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 | 45 mm | 1.7717 in |
| Outside diameter D | 85 mm | 3.3465 in |
| Width B | 23 mm | 0.9055 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Grease for 22209
Relubricating 22209 from the side takes about 9.78 g each time by the formula in our grease calculator: 0.005 × D × B = 0.005 × 85 × 23. 22209W33 has a lubrication groove and holes in the outer ring; when grease goes in through them the formula is 0.002 × D × B, about 3.91 g for 22209.
How FULI supplies 22209
The standard 22209 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 22209K/W33 C3.

FAQ
What is the difference between 22209 and 22309?
Both fit a 45 mm shaft. 22209 is 45 × 85 × 23 mm and 22309 is 45 × 100 × 36 mm, so 22309 has an outside diameter 15 mm larger (100 mm) and 13 mm more width (36 mm). In FULI's catalog 22309 has a dynamic load rating of 183 kN against 102 kN and a weight of about 1.40 kg against 0.59 kg for 22209. Choose 22309 for a higher load where the housing has room for it; 22209 keeps the housing smaller.
What size is 22209 in inches?
22209 is 1.7717 × 3.3465 × 0.9055 in (45 × 85 × 23 mm, d × D × B). The nearest common inch shaft size to the 45 mm bore of 22209 is 1-3/4 in (44.45 mm), 0.55 mm smaller than the bore, so 22209 would be loose on it. Use an inch bearing on an inch shaft.
How much does 22209 weigh?
About 0.59 kg in FULI's catalog, so 100 pieces weigh about 59 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
How much grease does 22209 need?
About 9.78 g each time it is relubricated from the side (0.005 × 85 × 23).
Is 22209 the same size across brands?
Bore d, outside diameter D and width B are the same: 22209 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).
