Bearing Cross Reference and Interchange Guide
Look up SKF, Timken, NSK, NTN, Koyo, NACHI and FAG part numbers for FULI ball bearings, tapered and spherical roller bearings and UC pillow block units.
Look up a brand part number
Size charts by series
Most metric ball bearings use the same basic number at every maker: a 6205 is 25 mm bore, 52 mm OD and 15 mm wide whether the box says SKF, NSK or FULI. What changes between brands is the suffix for seals, shields and clearance. Use the tables below to match another brand’s part number to the FULI number, then send us the list for a quote.
How bearing cross reference works
Same basic number, same boundary dimensions
ISO 15 sets the boundary dimensions of radial bearings: bore, outside diameter and width for each basic number. In a 6205, the last two digits are the bore code, and 05 × 5 = 25 mm. A 6205 from any maker that follows ISO 15 has the same bore, OD and width.
What the suffix tells you
After the basic number comes a suffix for seals or shields and, if needed, for internal clearance. Each maker writes these differently: a sealed 6205 is 6205-2RSH at SKF, 6205DDU at NSK and 6205-2RS at FULI. The table in the next section lines these up.
What a cross reference does not tell you
A cross reference matches the part number and the boundary dimensions. Load ratings, speed limits, cage material and grease are each maker’s own. FULI load ratings and speeds are on each model page and come from the FULI catalog.
Seal, shield and clearance suffixes by brand
One row per design, written the way each brand writes it for a 6205.
| FULI | Meaning | SKF | FAG | Timken | NSK | NTN | Koyo | NACHI |
|---|---|---|---|---|---|---|---|---|
| (none) | Open | 6205 | 6205-C | 6205 | 6205 | 6205 | 6205 | 6205 |
| ZZ | Metal shields, both sides | -2Z | -C-2Z | -ZZ | ZZ | ZZ | ZZ | ZZE |
| Z | Metal shield, one side | -Z | — | -Z | Z | Z | — | ZE |
| 2RS | Rubber contact seals, both sides | -2RSH (current) / -2RS1 (some sizes) | -C-2HRS | -2RS | DDU | LLU | 2RS | -2NSE |
| Not in FULI catalog | Non-contact rubber seals, both sides | — | — | -2RZ | VV | LLB | 2RU | -2NKE |
| Not in FULI catalog | Low-friction seals | -2RSL | — | — | — | LLH (low torque) | 2RD (extremely light contact) | — |
| C3 (on request) | Radial clearance larger than normal | /C3 (6205-2RSH/C3) | -C3 (6205-C-2HRS-C3) | -C3 (6205-2RS-C3) | C3 (6205DDUC3) | C3 (6205LLUC3) | C3 after the seal code | — |
A dash (—) means we have not confirmed that form in the brand’s own catalog or product pages. It does not mean the brand has no such bearing; send us the number and we will check it. Sources are listed at the end of the page.
FAG numbers are the current Generation C forms (6205-C, 6205-C-2Z, 6205-C-2HRS). The FULI catalog lists open, ZZ and 2RS versions. Radial clearance is C0 as standard and C3 on request. Non-contact and low-friction seals are not in the FULI catalog, so they are not matched to a FULI number here.
Cross reference by brand
- SKF to FULI cross reference: SKF and FAG numbers for the 6000, 6200 and 6300 series, with 2Z, 2RSH, 2RS1 and /C3 versions, plus SKF roller bearing suffixes (J2/Q, B, E, CC/W33, K).
- Timken and Fafnir to FULI cross reference: Timken -ZZ, -2RS and -C3 numbers, Fafnir KDD and PP numbers, Timken U Series housed units and the metric tapered roller table (30205 to 32212).
- NSK, NTN, Koyo and NACHI to FULI cross reference: NSK DDU, NTN LLU, Koyo 2RS and NACHI -2NSE numbers for the 6000, 6200 and 6300 series, with ZZ and C3 versions, plus roller bearing codes (HR…J, 4T-, JR, EAE4, EAD1, RZ, EX).
- Pillow block bearing cross reference: UCP, UCF and UCFL units against SKF, Timken, NTN and Koyo, plus Dodge, SealMaster, Browning and Fafnir numbers for inch shafts.
Cross reference by series
- 6000 series: 6000 to 6010, extra light series.
- 6200 series: 6200 to 6212, light series.
- 6300 series: 6300 to 6310, medium series.
- UCP 200 series: pillow block units.
- UCF and UCFL 200 series: four-bolt and two-bolt flange units.
6205 across brands: one worked example
| Version | FULI | SKF | FAG | Timken | NSK | NTN | Koyo | NACHI |
|---|---|---|---|---|---|---|---|---|
| Open | 6205 | 6205 | 6205-C | 6205 | 6205 | 6205 | 6205 | 6205 |
| Shields both sides | 6205ZZ | 6205-2Z | 6205-C-2Z | 6205-ZZ | 6205ZZ | 6205ZZ | 6205 ZZ | 6205ZZE |
| Contact seals both sides | 6205-2RS | 6205-2RSH | 6205-C-2HRS | 6205-2RS | 6205DDU | 6205LLU | 6205 2RS | 6205-2NSE |
| Contact seals + C3 | 6205-2RS C3 (on request) | 6205-2RSH/C3 | 6205-C-2HRS-C3 | 6205-2RS-C3 | 6205DDUC3 | 6205LLUC3 | — | — |
All eight are 25 × 52 × 15 mm. FULI 6205 dimensions are on the 6205 bearing page; load ratings and speeds are still being checked against FULI’s catalog, so ask for them with the quote.
Roller bearings: same basic number, different codes
Metric tapered and spherical roller bearings also share the basic number across makers, and the boundary dimensions match for the sizes below. The letters the makers add are design, cage, tapered bore and lubrication codes, not seal codes. One tapered example:
| FULI | Timken | SKF | NSK | NTN | Koyo | FAG |
|---|---|---|---|---|---|---|
| 30205 | 30205 | 30205 (ordered as 30205 J2/Q) | HR30205J | 4T-30205 | 30205JR | 30205-XL |
All 18 tapered sizes, 30205 to 32212, are in the Timken tapered roller table. Two of them need a note: the cone width B of 30304 is 15 or 16 mm depending on the maker, and SKF sells 32205 only as 32205 BJ2/Q, with a larger contact angle.
Spherical roller bearing cross reference
13 sizes with cylindrical bore. Timken is not in this table because we have not checked Timken spherical roller numbers; send us the Timken number and we will check it.
| FULI | d × D × B mm (FULI catalog) | SKF | NSK | NTN | Koyo | NACHI | FAG |

Dimensions are from the FULI catalog. Brand numbers are from each maker’s spherical roller bearing catalog; sources are listed at the end of the page. Each FULI number links to its product page.
Tapered bore. Every maker in the table adds K for a 1:12 tapered bore, for example SKF 22205 EK, NSK 22205CKE4, NTN 22205EAKD1, Koyo 22205RZK, NACHI 22205EXK and FAG 22205-E1-XL-K. Tapered-bore bearings fit an adapter sleeve, a withdrawal sleeve or a tapered shaft. Ask us for a FULI tapered-bore version.
Oil groove and three lubrication holes in the outer ring are written differently by each maker:
| Maker | How the groove and holes are shown | Example |
|---|---|---|
| SKF | Standard on E design, no suffix; CC design adds /W33 | 22205 E, 23022 CC/W33 |
| NSK | E4 in the number | 22205CE4 |
| NTN | D1 in the number | 22205EAD1 |
| Koyo | Add W33 | W33 suffix (Koyo catalog) |
| NACHI | Add W33 (W20 = holes only) | 22330E W33 (NACHI catalog) |
| FAG | Standard on E1 design, no suffix | 22205-E1-XL |
Tell us if your bearing needs the groove and holes and we will confirm the FULI version.
Mounted units: check the housing, not just the number
When the UC insert number is the same, the spherical outside diameter and the bore are the same. The housing is a separate check: center height and bolt hole spacing must match the machine. US two-bolt flange units from Dodge, SealMaster and Browning do not all share the bolt spacing of a JIS UCFL unit, so send the full unit number and we will compare the housing against the FULI catalog. See the pillow block bearing and flange bearing pages for FULI unit dimensions, and the pillow block bearing cross reference for unit numbers by brand.
How to send a cross reference request
- Brand and full part number, including every suffix (for example SKF 6205-2RSH/C3).
- Quantity for each line.
- Whether you need C3 clearance.
- What the bearing is used in, if you know it.
Paste the brand and full part numbers, including suffixes, with the quantity for each. We reply with the FULI number, price and lead time. Email sales@fuli-bearings.com or use the contact form.

FAQ
Is a FULI 6205 the same size as an SKF 6205 or NSK 6205?
Yes for boundary dimensions. The basic number 6205 means 25 mm bore, 52 mm OD and 15 mm width under ISO 15, and every maker in the table follows that plan. Load ratings and speed limits are each maker's own values; FULI values are on each model page.
What is the FULI equivalent of 2RSH, DDU or LLU?
All three are rubber contact seals on both sides. The FULI designation is 2RS, for example 6205-2RS.
Can I cross reference a non-contact seal such as NSK VV or NTN LLB?
The FULI catalog lists ZZ shields and 2RS contact seals. For a non-contact or low-friction seal, send the part number and we will tell you what we can supply before you order.
Does the guide cover tapered and spherical roller bearings?
Yes, for the sizes we have checked. The spherical roller table on this page covers 13 sizes from 22205 to 23022. The tapered roller table, 18 sizes from 30205 to 32212, is on the Timken cross reference page. On roller bearings the brand codes mark design, cage, tapered bore or oil groove and holes, not seals.
