How to read the 33207 designation
| Segment | Meaning |
|---|---|
| 3 | Single row tapered roller bearing (metric, ISO 355) |
| 32 | Dimension series 32 |
| 07 | Bore code 07 → 35 mm bore. ISO bore code (00–03 = 10/12/15/17 mm; 04 and above = code × 5 mm). |
33207 interchange
33207 is an ISO designation: bore d, outside diameter D and total width T are the same at each maker. The letters each maker adds are series, design or cage codes, not seal codes, so the full number is different at every brand. 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 33207
FULI makes 33207 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 35 × 72 × 28 mm size.
| Dimension | Nominal, mm | Deviation, µm | Limits, mm |
|---|---|---|---|
| Bore d (Δdmp) | 35 | 0 / −12 | 35.000 / 34.988 |
| Outside diameter D (ΔDmp) | 72 | 0 / −16 | 72.000 / 71.984 |
| Total width T (ΔTs) | 28 | +200 / 0 | 28.200 / 28.000 |
Δdmp and ΔDmp: deviation of the mean bore and mean outside diameter in one radial plane. ΔTs: assembled width of cone and cup, from the ISO 492 table for metric tapered roller bearings. Cone width B and cup width C: 0 / −120 µm each.
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 35 k5 for the shaft of 33207. The cup usually sits in an H7 or J7 housing bore so that it can be moved when the pair is adjusted.
| Seat | Deviation, µm | Limits, mm | Fit with 33207 |
|---|---|---|---|
| Shaft 35 k5 | +13 / +2 | 35.013 / 35.002 | 2 to 25 µm interference |
| Housing 72 H7 | +30 / 0 | 72.030 / 72.000 | 0 to 46 µm clearance |
| Housing 72 J7 | +18 / −12 | 72.018 / 71.988 | 12 µm interference to 34 µm clearance |
Taking the loosest and the tightest combination of limits, a P0 33207 on a 35 mm k5 shaft has 2 to 25 µm interference. Its cup has 0 to 46 µm clearance in an H7 bore and 12 µm interference to 34 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.
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).

33207 compared with nearby sizes
33207 measures 35 × 72 × 28 mm: bore d, outside diameter D and total width T. Other tapered roller bearings on this site for the same 35 mm shaft are 32007 (35 × 62 × 18 mm), 30207 (35 × 72 × 18.25 mm), 32207 (35 × 72 × 24.25 mm), 30307 (35 × 80 × 22.75 mm) and 31307 (35 × 80 × 22.75 mm).
30307 is the next heavier choice for a 35 mm shaft, with an outside diameter 8 mm larger (80 mm) and 5.25 mm less width (22.75 mm). In FULI's catalog 30307 has a dynamic load rating of 75.30 kN against 82.60 kN and a weight of about 0.515 kg against 0.52 kg for 33207.
32207 is the lighter option on the same shaft, with the same 72 mm outside diameter and 3.75 mm less width (24.25 mm), for housings with less room. In FULI's catalog 32207 has a dynamic load rating of 70.60 kN against 82.60 kN and a weight of about 0.447 kg against 0.52 kg for 33207.
30306 has the same 72 mm outside diameter with a 30 mm bore, so it fits the same housing bore on a smaller shaft.
In the 332 series the sizes either side of 33207 are 33206 for a 30 mm shaft and 33210 for a 50 mm shaft.

33207 weight, load ratings and speed
FULI's catalog gives the weight of 33207 as about 0.52 kg, so 100 bearings weigh about 52 kg and 1,000 about 520 kg before packing. The weight is for the cone and cup together.
33207 has a dynamic load rating Cr of 82.60 kN and a static load rating C0r of 101.70 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.
Values from FULI's catalog; confirm for your application.
33207 cone and cup
33207 is supplied as a complete bearing: the cone (inner ring with rollers and cage) and the cup (outer ring). The total width T of 28 mm applies when the two are assembled; the cone and the cup on their own are each narrower. Tell us if you need only the cone or only the cup.
Tapered roller bearings carry radial load and axial load in one direction, so 33207 is normally mounted as one of a pair facing each other, and the end play or preload is set when the pair is adjusted on the shaft. That is why FULI lists the clearance as set during mounting, not as a C-class value.
33207 dimensions in inches
The nearest common inch shaft size to the 35 mm bore of 33207 is 1-3/8 in (34.93 mm), 0.07 mm smaller than the bore, so 33207 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 | 35 mm | 1.3780 in |
| Outside diameter D | 72 mm | 2.8346 in |
| Total width T | 28 mm | 1.1024 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Grease for 33207
FULI supplies tapered roller bearings rust-protected and normally without grease; grease is added when 33207 is mounted. Relubricating 33207 from the side takes about 10.1 g each time by the formula in our grease calculator: 0.005 × D × T = 0.005 × 72 × 28.
How FULI supplies 33207
The standard 33207 from FULI has GCr15 chrome steel rings and rollers and P0 precision, with P6 on request. Where an order states a requirement for the total width T (28 mm for 33207) or the cone height, each set is checked on a height gauge.
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 33207.

FAQ
What is the difference between 33207 and 30307?
Both fit a 35 mm shaft. 33207 is 35 × 72 × 28 mm and 30307 is 35 × 80 × 22.75 mm, so 30307 has an outside diameter 8 mm larger (80 mm) and 5.25 mm less width (22.75 mm). In FULI's catalog 30307 has a dynamic load rating of 75.30 kN against 82.60 kN and a weight of about 0.515 kg against 0.52 kg for 33207. Choose 30307 for a higher load where the housing has room for it; 33207 keeps the housing smaller.
What is the difference between 33207 and 32207?
Both fit a 35 mm shaft. 33207 is 35 × 72 × 28 mm and 32207 is 35 × 72 × 24.25 mm, so 32207 has the same 72 mm outside diameter and 3.75 mm less width (24.25 mm). In FULI's catalog 32207 has a dynamic load rating of 70.60 kN against 82.60 kN and a weight of about 0.447 kg against 0.52 kg for 33207. 32207 suits a housing with less room; 33207 carries more load.
What size is 33207 in inches?
33207 is 1.3780 × 2.8346 × 1.1024 in (35 × 72 × 28 mm, d × D × T). The nearest common inch shaft size to the 35 mm bore of 33207 is 1-3/8 in (34.93 mm), 0.07 mm smaller than the bore, so 33207 would be loose on it. Use an inch bearing on an inch shaft.
How much does 33207 weigh?
About 0.52 kg in FULI's catalog, so 100 pieces weigh about 52 kg before packing. The weight is for the cone and cup together.
How much grease does 33207 need?
About 10.1 g each time it is relubricated from the side (0.005 × 72 × 28). FULI ships 33207 rust-protected without grease, so the first fill is made at mounting.
Is 33207 the same size across brands?
Bore d, outside diameter D and total width T are the same: 33207 is an ISO designation. The letters each maker adds (NSK HR and J, NTN 4T-, Koyo JR, FAG XL, SKF J2/Q) are series, design or cage codes, not seal codes.
