22210 cross reference by brand
22210 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 22210
FULI makes 22210 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 50 × 90 × 23 mm size.
| Dimension | Nominal, mm | Deviation, µm | Limits, mm |
|---|---|---|---|
| Bore d (Δdmp) | 50 | 0 / −12 | 50.000 / 49.988 |
| Outside diameter D (ΔDmp) | 90 | 0 / −15 | 90.000 / 89.985 |
| 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 50 m5 for the shaft of 22210. The housing bore is usually H7, or J7 where the outer ring must not creep.
| Seat | Deviation, µm | Limits, mm | Fit with 22210 |
|---|---|---|---|
| Shaft 50 m5 | +20 / +9 | 50.020 / 50.009 | 9 to 32 µm interference |
| Housing 90 H7 | +35 / 0 | 90.035 / 90.000 | 0 to 50 µm clearance |
| Housing 90 J7 | +22 / −13 | 90.022 / 89.987 | 13 µm interference to 37 µm clearance |
Taking the loosest and the tightest combination of limits, a P0 22210 on a 50 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).

22210 compared with nearby sizes
22210 measures 50 × 90 × 23 mm: bore d, outside diameter D and width B. Other spherical roller bearings on this site for the same 50 mm shaft are 22310 (50 × 110 × 40 mm).
22310 is the next heavier choice for a 50 mm shaft, with an outside diameter 20 mm larger (110 mm) and 17 mm more width (40 mm). In FULI's catalog 22310 has a dynamic load rating of 220 kN against 104 kN and a weight of about 1.90 kg against 0.63 kg for 22210.
21308 has the same 90 mm outside diameter with a 40 mm bore, so it fits the same housing bore on a smaller shaft.
22308 has the same 90 mm outside diameter with a 40 mm bore, so it fits the same housing bore on a smaller shaft.
In the 222 series the sizes either side of 22210 are 22209 for a 45 mm shaft and 22211 for a 55 mm shaft.

22210 weight, load ratings and speed
FULI's catalog gives the weight of 22210 as about 0.63 kg, so 100 bearings weigh about 63 kg and 1,000 about 630 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
22210 has a dynamic load rating Cr of 104 kN and a static load rating C0r of 108 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, 7,000 and 9,500 rpm, without stating the lubrication for each column.

22210 bore and clearance versions
FULI's catalog lists 22210 in two bore versions on one line, both 50 × 90 × 23 mm: 22210W33 with a cylindrical bore and 22210K/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 |
|---|---|
| 22210W33 | Cylindrical 50 mm bore, lubrication groove and holes, C0 clearance |
| 22210K/W33 | Tapered bore 1:12 for sleeve mounting, lubrication groove and holes |
| 22210W33 C3 | Cylindrical bore with C3 radial clearance |
| 22210K/W33 C3 | Tapered bore with C3 radial clearance |
22210 dimensions in inches
The nearest common inch shaft size to the 50 mm bore of 22210 is 1-15/16 in (49.21 mm), 0.79 mm smaller than the bore, so 22210 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 | 50 mm | 1.9685 in |
| Outside diameter D | 90 mm | 3.5433 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 22210
Relubricating 22210 from the side takes about 10.3 g each time by the formula in our grease calculator: 0.005 × D × B = 0.005 × 90 × 23. 22210W33 has a lubrication groove and holes in the outer ring; when grease goes in through them the formula is 0.002 × D × B, about 4.14 g for 22210.
How FULI supplies 22210

FAQ
What is the difference between 22210 and 22310?
Both fit a 50 mm shaft. 22210 is 50 × 90 × 23 mm and 22310 is 50 × 110 × 40 mm, so 22310 has an outside diameter 20 mm larger (110 mm) and 17 mm more width (40 mm). In FULI's catalog 22310 has a dynamic load rating of 220 kN against 104 kN and a weight of about 1.90 kg against 0.63 kg for 22210. Choose 22310 for a higher load where the housing has room for it; 22210 keeps the housing smaller.
What size is 22210 in inches?
22210 is 1.9685 × 3.5433 × 0.9055 in (50 × 90 × 23 mm, d × D × B). The nearest common inch shaft size to the 50 mm bore of 22210 is 1-15/16 in (49.21 mm), 0.79 mm smaller than the bore, so 22210 would be loose on it. Use an inch bearing on an inch shaft.
How much does 22210 weigh?
About 0.63 kg in FULI's catalog, so 100 pieces weigh about 63 kg before packing. The cylindrical bore (W33) and tapered bore (K/W33) versions share this catalog line.
How much grease does 22210 need?
About 10.3 g each time it is relubricated from the side (0.005 × 90 × 23).
Is 22210 the same size across brands?
Bore d, outside diameter D and width B are the same: 22210 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).
