| Segment | Meaning |
|---|---|
| 2 | Spherical roller bearing (double row, self-aligning) |
| 30 | Dimension series 30 |

23022 cross reference by brand
23022 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.

- For 23022 the SKF design is CC with /W33 in the number, NSK lists CDE4 and NACHI lists 23022E. We have seen FAG's tapered-bore 23022 only with C3 clearance, so that cell says ask us.

Tolerances and fits for 23022
FULI makes 23022 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 110 × 170 × 45 mm size.
| Dimension | Nominal, mm | Deviation, µm | Limits, mm |
|---|---|---|---|
| Bore d (Δdmp) | 110 | 0 / −20 | 110.000 / 109.980 |
| Outside diameter D (ΔDmp) | 170 | 0 / −25 | 170.000 / 169.975 |
| Width B (ΔBs) | 45 | 0 / −200 | 45.000 / 44.800 |
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 110 n6 for the shaft of 23022. The housing bore is usually H7, or J7 where the outer ring must not creep.
| Seat | Deviation, µm | Limits, mm | Fit with 23022 |
|---|---|---|---|
| Shaft 110 n6 | +45 / +23 | 110.045 / 110.023 | 23 to 65 µm interference |
| Housing 170 H7 | +40 / 0 | 170.040 / 170.000 | 0 to 65 µm clearance |
| Housing 170 J7 | +26 / −14 | 170.026 / 169.986 | 14 µm interference to 51 µm clearance |
Taking the loosest and the tightest combination of limits, a P0 23022 on a 110 mm n6 shaft has 23 to 65 µm interference. Its outer ring has 0 to 65 µm clearance in an H7 bore and 14 µm interference to 51 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).

23022 compared with nearby sizes
23022 measures 110 × 170 × 45 mm: bore d, outside diameter D and width B. Other spherical roller bearings on this site for the same 110 mm shaft are 22222 (110 × 200 × 53 mm) and 23222 (110 × 200 × 69.8 mm).
22222 is the next heavier choice for a 110 mm shaft, with an outside diameter 30 mm larger (200 mm) and 8 mm more width (53 mm). In FULI's catalog 22222 has a weight of about 7.00 kg against 3.80 kg for 23022.
22316 has the same 170 mm outside diameter with a 80 mm bore, so it fits the same housing bore on a smaller shaft.
In the 230 series the sizes either side of 23022 are 23024 for a 120 mm shaft.

23022 weight
FULI's catalog gives the weight of 23022 as about 3.80 kg, so 100 bearings weigh about 380 kg and 1,000 about 3800 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.

23022 bore and clearance versions
FULI's catalog lists 23022 in two bore versions on one line, both 110 × 170 × 45 mm: 23022W33 with a cylindrical bore and 23022K/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 |
|---|---|
| 23022W33 | Cylindrical 110 mm bore, lubrication groove and holes, C0 clearance |
| 23022K/W33 | Tapered bore 1:12 for sleeve mounting, lubrication groove and holes |
| 23022W33 C3 | Cylindrical bore with C3 radial clearance |
| 23022K/W33 C3 | Tapered bore with C3 radial clearance |
23022 dimensions in inches
The nearest common inch shaft size to the 110 mm bore of 23022 is 4-5/16 in (109.54 mm), 0.46 mm smaller than the bore, so 23022 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 | 110 mm | 4.3307 in |
| Outside diameter D | 170 mm | 6.6929 in |
| Width B | 45 mm | 1.7717 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Grease for 23022
Relubricating 23022 from the side takes about 38.3 g each time by the formula in our grease calculator: 0.005 × D × B = 0.005 × 170 × 45. 23022W33 has a lubrication groove and holes in the outer ring; when grease goes in through them the formula is 0.002 × D × B, about 15.3 g for 23022.
How FULI supplies 23022
The standard 23022 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 23022K/W33 C3.

FAQ
What is the difference between 23022 and 22222?
Both fit a 110 mm shaft. 23022 is 110 × 170 × 45 mm and 22222 is 110 × 200 × 53 mm, so 22222 has an outside diameter 30 mm larger (200 mm) and 8 mm more width (53 mm). In FULI's catalog 22222 has a weight of about 7.00 kg against 3.80 kg for 23022. Choose 22222 for a higher load where the housing has room for it; 23022 keeps the housing smaller.
What size is 23022 in inches?
23022 is 4.3307 × 6.6929 × 1.7717 in (110 × 170 × 45 mm, d × D × B). The nearest common inch shaft size to the 110 mm bore of 23022 is 4-5/16 in (109.54 mm), 0.46 mm smaller than the bore, so 23022 would be loose on it. Use an inch bearing on an inch shaft.
How much does 23022 weigh?
About 3.80 kg in FULI's catalog, so 100 pieces weigh about 380 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
How much grease does 23022 need?
About 38.3 g each time it is relubricated from the side (0.005 × 170 × 45).
Is 23022 the same size across brands?
Bore d, outside diameter D and width B are the same: 23022 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).
Where are the load ratings for 23022?
Load ratings for 23022 are being checked against FULI's catalog and are not shown on this page yet. Model pages with a "Load ratings & speed" table carry values from FULI's catalog.
