6205 Bearing Dimensions
The ENRO 6205 is a deep groove ball bearing in the 6200 series, 25 × 52 × 15 mm. Typical applications: Motorcycle hubs, electric motors, pumps. Boundary dimensions follow the ISO 15 dimension series.
Three checks for the 6205
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 6205 is 25 × 52 × 15 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 4 versions: 6205, 6205-ZZ, 6205-2RS, 6205-NR. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 12.60 kN, C0r 7.54 kN (catalog reference values). Check the life at your load and speed.

Deep groove ball bearing 6205 designation
- 62 — bearing type and dimension series code.
- 05 — bore code: code 05 × 5 = 25 mm.
6205 variants: 6205 / 6205-ZZ / 6205-2RS / 6205-NR
| Order as | Meaning |
|---|---|
| 6205 | Open. No shields or seals. Lubricated in service by grease or oil. |
| 6205-ZZ | Metal shields, both sides. Non-contact steel shields. Low friction; keeps out larger particles. |
| 6205-2RS | Rubber seals, both sides. Contact rubber seals. Better protection against dust and water; slightly higher friction. |
| 6205-NR | Snap ring groove with snap ring. Snap ring on the outer ring for axial location in the housing. |

Where the 6205 is used
Positions ENRO lists for this size, the versions to name on the RFQ and what to check first.
Typical applications
Motorcycle hubs, electric motors, pumps. These are the positions ENRO lists for the 6205; confirm against the marking on the bearing being replaced.
Versions to ask for
6205 (open), 6205-ZZ (metal shields, both sides), 6205-2RS (rubber seals, both sides), 6205-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: 25 × 52 × 15 mm. Shield or seal type and the clearance group (CN or C3) of the old bearing. Catalog Cr 12.60 kN against your load; run the life calculator if the position is loaded.
Selection notes from the table
- The 6205 is the seventh of thirty-one sizes ENRO lists in the 6200 series, 25 × 52 × 15 mm.
- Next size down, the 62/22, is 22 × 50 × 14 mm: three millimetres less bore, two millimetres less outside diameter, one millimetre narrower.
- Next size up, the 62/28, is 28 × 58 × 16 mm: three millimetres more bore, six millimetres more outside diameter, one millimetre wider.
- Seven other ENRO deep groove ball bearings share the 25 mm bore: the 6005 (6000 series) is 47 × 12 mm, five millimetres less outside diameter and three millimetres narrower; the 6305 (6300 series) is 62 × 17 mm, ten millimetres more outside diameter and two millimetres wider.
- The 6205 has a radial section of 13.5 mm ((D − d) / 2) on a 15 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 6205: Cr 12.60 kN, C0r 7.54 kN, limiting speed 12,000 rpm with grease, 14,000 rpm with oil, weight 0.129 kg.
- Catalog dynamic load rating Cr is 12.60 kN for the 6205 against 11.61 kN for the 62/22 (slightly less, 0.99 kN or 8%) and 16.11 kN for the 62/28 (substantially more, 3.51 kN or 28%).
- ENRO lists the 6205 in four versions: 6205, 6205-ZZ, 6205-2RS, 6205-NR. In the same series, the 62/22 is listed without snap ring groove with snap ring; the 62/28 is listed in the same four versions.

Is the ENRO 6205 interchangeable with other brands' 6205?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 6205 is dimensionally interchangeable with other brands' 6205 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 6205-ZZ and 6205-2RS?
6205-ZZ has metal shields, both sides: Non-contact steel shields. Low friction; keeps out larger particles. 6205-2RS 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 6205?
In the ENRO range, 6705 (25 × 32 × 4 mm), 6805 (25 × 37 × 7 mm), 6905 (25 × 42 × 9 mm), 16005 (25 × 47 × 8 mm) share the 25 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 6205?
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 6205?
Deep Groove Ball Bearings are classified under HS Code 8482.10. Confirm the code with your customs broker.
