6208 Bearing Dimensions
The ENRO 6208 is a deep groove ball bearing in the 6200 series, 40 × 80 × 18 mm. Typical applications: Motors, industrial machinery. Boundary dimensions follow the ISO 15 dimension series.
Three checks for the 6208
Most wrong replacements come from one of these. Each answer below comes from the ENRO model table.
Does the size match?
Measure bore, outside diameter and width. The 6208 is 40 × 80 × 18 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 4 versions: 6208, 6208-ZZ, 6208-2RS, 6208-NR. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 26.19 kN, C0r 17.09 kN (catalog reference values). Check the life at your load and speed.

What “6208” means
- 62 — bearing type and dimension series code.
- 08 — bore code: code 08 × 5 = 40 mm.
6208 variants: 6208 / 6208-ZZ / 6208-2RS / 6208-NR
| Order as | Meaning |
|---|---|
| 6208 | Open. No shields or seals. Lubricated in service by grease or oil. |
| 6208-ZZ | Metal shields, both sides. Non-contact steel shields. Low friction; keeps out larger particles. |
| 6208-2RS | Rubber seals, both sides. Contact rubber seals. Better protection against dust and water; slightly higher friction. |
| 6208-NR | Snap ring groove with snap ring. Snap ring on the outer ring for axial location in the housing. |

Where the 6208 is used
Positions ENRO lists for this size, the versions to name on the RFQ and what to check first.
Typical applications
Motors, industrial machinery. These are the positions ENRO lists for the 6208; confirm against the marking on the bearing being replaced.
Versions to ask for
6208 (open), 6208-ZZ (metal shields, both sides), 6208-2RS (rubber seals, both sides), 6208-NR (snap ring groove with snap ring). Open, shielded (ZZ), sealed (2RS) or snap ring (NR).
What to check before ordering
Bore, outside diameter and width: 40 × 80 × 18 mm. Shield or seal type and the clearance group (CN or C3) of the old bearing. Catalog Cr 26.19 kN against your load; run the life calculator if the position is loaded.
Selection notes from the table
- The 6208 is the twelfth of thirty-one sizes ENRO lists in the 6200 series, 40 × 80 × 18 mm.
- Next size down, the 6207, is 35 × 72 × 17 mm: five millimetres less bore, eight millimetres less outside diameter, one millimetre narrower.
- Next size up, the 6209, is 45 × 85 × 19 mm: five millimetres more bore, five millimetres more outside diameter, one millimetre wider.
- Six other ENRO deep groove ball bearings share the 40 mm bore: the 6008 (6000 series) is 68 × 15 mm, twelve millimetres less outside diameter and three millimetres narrower; the 6308 (6300 series) is 90 × 23 mm, ten millimetres more outside diameter and five millimetres wider.
- The 6208 has a radial section of 20 mm ((D − d) / 2) on a 18 mm width, so its cross-section is taller than it is wide.
- Catalog reference values for the 6208: Cr 26.19 kN, C0r 17.09 kN, limiting speed 8,300 rpm with grease, 9,500 rpm with oil, weight 0.366 kg.
- Catalog dynamic load rating Cr is 26.19 kN for the 6208 against 23.13 kN for the 6207 (noticeably less, 3.06 kN or 12%) and 29.25 kN for the 6209 (noticeably more, 3.06 kN or 12%).
- ENRO lists the 6208 in four versions: 6208, 6208-ZZ, 6208-2RS, 6208-NR. In the same series, the 6207 is listed in the same four versions; the 6209 is listed in the same four versions.

Is the ENRO 6208 interchangeable with other brands' 6208?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 6208 is dimensionally interchangeable with other brands' 6208 of the same size. Confirm seal, clearance and cage requirements in your RFQ.
Where are ENRO bearings made?
ENRO bearings are Made in China by partner factories, under Japan-managed quality control. Every unit passes 100% outgoing inspection before shipment.
What is the difference between 6208-ZZ and 6208-2RS?
6208-ZZ has metal shields, both sides: Non-contact steel shields. Low friction; keeps out larger particles. 6208-2RS has rubber seals, both sides: Contact rubber seals. Better protection against dust and water; slightly higher friction. Boundary dimensions are the same.
Which bearings have the same bore as the 6208?
In the ENRO range, 6808 (40 × 52 × 7 mm), 6908 (40 × 62 × 12 mm), 16008 (40 × 68 × 9 mm), 6008 (40 × 68 × 15 mm) share the 40 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 6208?
CN (normal) suits most positions. C3 is common where the inner ring runs warmer than the outer ring, as in electric motors. Groups are defined in ISO 5753-1; state the one you need in your RFQ.
What is the HS code for the 6208?
Deep Groove Ball Bearings are classified under HS Code 8482.10. Confirm the code with your customs broker.
