How to read the 22309 designation
| Segment | Meaning |
|---|---|
| 2 | Spherical roller bearing (double row, self-aligning) |
| 23 | Dimension series 23 |
| 09 | Bore code 09 → 45 mm bore. ISO bore code (00–03 = 10/12/15/17 mm; 04 and above = code × 5 mm). |
22309 interchange
22309 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.
Brand names are trademarks of their respective owners. FULI is not affiliated with, authorized by or endorsed by these companies. Part numbers are shown for interchange reference only. FULI dimensions, load ratings and speeds come from the FULI catalog.
Tolerances and fits for 22309
FULI makes 22309 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 × 100 × 36 mm size.
| Dimension | Nominal, mm | Deviation, µm | Limits, mm |
|---|---|---|---|
| Bore d (Δdmp) | 45 | 0 / −12 | 45.000 / 44.988 |
| Outside diameter D (ΔDmp) | 100 | 0 / −15 | 100.000 / 99.985 |
| Width B (ΔBs) | 36 | 0 / −120 | 36.000 / 35.880 |
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 22309. The housing bore is usually H7, or J7 where the outer ring must not creep.
| Seat | Deviation, µm | Limits, mm | Fit with 22309 |
|---|---|---|---|
| Shaft 45 m5 | +20 / +9 | 45.020 / 45.009 | 9 to 32 µm interference |
| Housing 100 H7 | +35 / 0 | 100.035 / 100.000 | 0 to 50 µm clearance |
| Housing 100 J7 | +22 / −13 | 100.022 / 99.987 | 13 µm interference to 37 µm clearance |
Taking the loosest and the tightest combination of limits, a P0 22309 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).

22309 compared with nearby sizes
22309 measures 45 × 100 × 36 mm: bore d, outside diameter D and width B. Other spherical roller bearings on this site for the same 45 mm shaft are 22209 (45 × 85 × 23 mm).
22209 is the lighter option on the same shaft, with an outside diameter 15 mm smaller (85 mm) and 13 mm less width (23 mm), for housings with less room. In FULI's catalog 22209 has a dynamic load rating of 102 kN against 183 kN and a weight of about 0.59 kg against 1.40 kg for 22309.
22211 has the same 100 mm outside diameter with a 55 mm bore, so it fits the same housing bore on a larger shaft.
In the 223 series the sizes either side of 22309 are 22308 for a 40 mm shaft and 22310 for a 50 mm shaft.

22309 weight, load ratings and speed
FULI's catalog gives the weight of 22309 as about 1.40 kg, so 100 bearings weigh about 140 kg and 1,000 about 1400 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
22309 has a dynamic load rating Cr of 183 kN and a static load rating C0r of 183 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, 5,300 and 7,000 rpm, without stating the lubrication for each column.

22309 bore and clearance versions
FULI's catalog lists 22309 in two bore versions on one line, both 45 × 100 × 36 mm: 22309W33 with a cylindrical bore and 22309K/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 |
|---|---|
| 22309W33 | Cylindrical 45 mm bore, lubrication groove and holes, C0 clearance |
| 22309K/W33 | Tapered bore 1:12 for sleeve mounting, lubrication groove and holes |
| 22309W33 C3 | Cylindrical bore with C3 radial clearance |
| 22309K/W33 C3 | Tapered bore with C3 radial clearance |
22309 dimensions in inches
The nearest common inch shaft size to the 45 mm bore of 22309 is 1-3/4 in (44.45 mm), 0.55 mm smaller than the bore, so 22309 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 | 100 mm | 3.9370 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 22309
Relubricating 22309 from the side takes about 18.0 g each time by the formula in our grease calculator: 0.005 × D × B = 0.005 × 100 × 36. 22309W33 has a lubrication groove and holes in the outer ring; when grease goes in through them the formula is 0.002 × D × B, about 7.20 g for 22309.
How FULI supplies 22309
The standard 22309 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 22309K/W33 C3.

FAQ
What is the difference between 22309 and 22209?
Both fit a 45 mm shaft. 22309 is 45 × 100 × 36 mm and 22209 is 45 × 85 × 23 mm, so 22209 has an outside diameter 15 mm smaller (85 mm) and 13 mm less width (23 mm). In FULI's catalog 22209 has a dynamic load rating of 102 kN against 183 kN and a weight of about 0.59 kg against 1.40 kg for 22309. 22209 suits a housing with less room; 22309 carries more load.
What size is 22309 in inches?
22309 is 1.7717 × 3.9370 × 1.4173 in (45 × 100 × 36 mm, d × D × B). The nearest common inch shaft size to the 45 mm bore of 22309 is 1-3/4 in (44.45 mm), 0.55 mm smaller than the bore, so 22309 would be loose on it. Use an inch bearing on an inch shaft.
How much does 22309 weigh?
About 1.40 kg in FULI's catalog, so 100 pieces weigh about 140 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
How much grease does 22309 need?
About 18.0 g each time it is relubricated from the side (0.005 × 100 × 36).
Is 22309 the same size across brands?
Bore d, outside diameter D and width B are the same: 22309 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).
