Timken Bearing Cross Reference: Timken and Fafnir Numbers to ENRO
Find the ENRO number for a Timken or Fafnir deep groove ball bearing. Timken 6205-2RS, Fafnir 205PP and ENRO 6205-2RS are all 25 × 52 × 15 mm with seals on both sides and are dimensionally interchangeable. The table covers the 35 sizes from 6000 to 6310 that ENRO lists.
How Timken writes a ball bearing number
The match is by boundary dimensions only: bore d, outside diameter D and width B. Boundary dimensions follow the ISO 15 dimension series. Timken's metric deep groove ball bearings use the ISO base number with hyphenated suffixes, so the translation to ENRO is short.
| Timken writes | What it is | Write on the ENRO order |
|---|---|---|
| 6205 | Open bearing | Open: 6205 |
| 6205-ZZ | Shields on both sides | ZZ: 6205-ZZ |
| 6205-2RS | Contact seals on both sides | 2RS: 6205-2RS |
| 6205-C3, 6205-ZZ-C3, 6205-2RS-C3 | Clearance larger than normal, written last | Add C3 after the ENRO number |
Timken uses ZZ, not 2Z, so a Timken shielded number and an ENRO shielded number read almost the same. The only change is where C3 goes: Timken writes 6205-2RS-C3, ENRO writes 6205-2RS C3.
Timken and Fafnir to ENRO: 35 deep groove ball bearing sizes
Timken writes its ball bearing suffixes the way ENRO does, with a hyphen: -ZZ for shields and -2RS for contact seals. The Fafnir columns give the older Fafnir number for the same size and closure.

Dimensions are from the ENRO catalogue. "Ask us": the number has not passed our source check yet, so it is left out. Send it and we will confirm it. Timken lists the open 6200-C0 with -C0 (normal clearance) written out.
Reading a Fafnir number
Fafnir is a ball bearing brand owned by Timken, and Fafnir numbers still turn up on old bearings and in maintenance records. They do not follow the ISO pattern, so they need a key.
| Fafnir part | Meaning | Example | ISO base number |
|---|---|---|---|
| 9100 + bore code | Extra-light series | 9105 | 6005 |
| 200 + bore code | Light series | 205 | 6205 |
| 300 + bore code | Medium series | 305 | 6305 |
| K | Open bearing | 205K | 6205 |
| KDD | Shields on both sides | 205KDD | 6205 with shields: ENRO 6205-ZZ |
| PP | Seals on both sides | 205PP | 6205 with seals: ENRO 6205-2RS |
So the bore code works the same way as in an ISO number. Drop the Fafnir series prefix, put 60, 62 or 63 in front of the bore code, and translate KDD to ZZ or PP to 2RS.
Worked example: replacing a Fafnir 205PP
- 205 is the light series with bore code 05, so the ISO base number is 6205: 25 × 52 × 15 mm. See ENRO 6205.
- PP means seals on both sides. The ENRO code is 2RS.
- The ENRO number is 6205-2RS. If the drawing calls for C3, the Timken number is 6205-2RS-C3. ENRO deep groove ball bearings are offered in C0 (CN), C3 clearance. Add C3 after the ENRO number, for example 6205-2RS C3.
Put the Fafnir number and the ENRO number on the same line of your enquiry so we can check the translation before quoting.
Before you send a Timken or Fafnir list
- Copy each number exactly as marked or as written in your stores system.
- Fafnir numbers with letters other than K, KDD or PP need a check. Send them as written.
- Keep the clearance group of the old bearing. If it said C3, order C3.
- Sizes outside 6000–6310 are on the deep groove ball bearing page.

Timken and Fafnir cross reference FAQ
What is the ENRO equivalent of Timken 6205-2RS?
ENRO 6205-2RS. Both are 25 × 52 × 15 mm (d × D × B) with contact seals on both sides, so they are dimensionally interchangeable.
What does KDD mean on a Fafnir bearing?
KDD is a Fafnir ball bearing with a shield on each side. 205KDD is the 6205 size, so the ENRO number is 6205-ZZ. PP means seals on both sides (ENRO 2RS) and K alone is the open bearing.
How do I convert a Fafnir 9100-series number?
The 9100 series is the extra-light series, ISO 60. Keep the last two digits as the bore code: 9105 is 6005, 9108 is 6008. Then translate the closure letters: KDD to ZZ, PP to 2RS.
Why do some Fafnir cells say "ask us"?
For those sizes the Fafnir number has not passed our source check yet, so we do not print it. The ENRO size is not in doubt; send the Fafnir number and we will confirm the match.
A cell says "ask us". What does that mean?
A number is printed only after it has been checked against the maker's published data or against more than one independent source. "Ask us" means that check is not finished for this cell, so we leave it blank rather than guess. Send the number you have and we will confirm it before quoting.
Can I send a whole parts list in one go?
Yes. Paste the numbers as they are written on the old bearings or in your maintenance records, with quantities. We return the ENRO number and dimensions next to each line. We reply within 24 hours on business days.
