6201 Bearing Dimensions
The ENRO 6201 is a deep groove ball bearing in the 6200 series, 12 × 32 × 10 mm. Typical applications: Motorcycle wheel hubs, small electric motors. Boundary dimensions follow the ISO 15 dimension series.
Three checks for the 6201
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 6201 is 12 × 32 × 10 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 4 versions: 6201, 6201-ZZ, 6201-2RS, 6201-NR. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 5.49 kN, C0r 2.75 kN (catalog reference values). Check the life at your load and speed.

What “6201” means
- 62 — bearing type and dimension series code.
- 01 — bore code: code 01 is a fixed code for 12 mm.
6201 variants: 6201 / 6201-ZZ / 6201-2RS / 6201-NR
| Order as | Meaning |
|---|---|
| 6201 | Open. No shields or seals. Lubricated in service by grease or oil. |
| 6201-ZZ | Metal shields, both sides. Non-contact steel shields. Low friction; keeps out larger particles. |
| 6201-2RS | Rubber seals, both sides. Contact rubber seals. Better protection against dust and water; slightly higher friction. |
| 6201-NR | Snap ring groove with snap ring. Snap ring on the outer ring for axial location in the housing. |

Where the 6201 is used
Positions ENRO lists for this size, the versions to name on the RFQ and what to check first.
Typical applications
Motorcycle wheel hubs, small electric motors. These are the positions ENRO lists for the 6201; confirm against the marking on the bearing being replaced.
Versions to ask for
6201 (open), 6201-ZZ (metal shields, both sides), 6201-2RS (rubber seals, both sides), 6201-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: 12 × 32 × 10 mm. Shield or seal type and the clearance group (CN or C3) of the old bearing. Catalog Cr 5.49 kN against your load; run the life calculator if the position is loaded.
Selection notes from the table
- The 6201 is the second of thirty-one sizes ENRO lists in the 6200 series, 12 × 32 × 10 mm.
- Next size down, the 6200, is 10 × 30 × 9 mm: two millimetres less bore, two millimetres less outside diameter, one millimetre narrower.
- Next size up, the 6202, is 15 × 35 × 11 mm: three millimetres more bore, three millimetres more outside diameter, one millimetre wider.
- Six other ENRO deep groove ball bearings share the 12 mm bore: the 6001 (6000 series) is 28 × 8 mm, four millimetres less outside diameter and two millimetres narrower; the 6301 (6300 series) is 37 × 12 mm, five millimetres more outside diameter and two millimetres wider.
- The 6201 has a radial section of 10 mm ((D − d) / 2) on a 10 mm width, so its cross-section is square.
- Catalog reference values for the 6201: Cr 5.49 kN, C0r 2.75 kN, limiting speed 21,000 rpm with grease, 25,000 rpm with oil, weight 0.037 kg.
- Catalog dynamic load rating Cr is 5.49 kN for the 6201 against 4.59 kN for the 6200 (noticeably less, 0.9 kN or 16%) and 6.98 kN for the 6202 (substantially more, 1.49 kN or 27%).
- ENRO lists the 6201 in four versions: 6201, 6201-ZZ, 6201-2RS, 6201-NR. In the same series, the 6200 is listed in the same four versions; the 6202 is listed in the same four versions.

Which versions of the 6201 can I order?
ENRO lists the 6201 as 6201 (Open), 6201-ZZ (Metal shields, both sides), 6201-2RS (Rubber seals, both sides), 6201-NR (Snap ring groove with snap ring). State the clearance group you need in your RFQ.
Is the ENRO 6201 interchangeable with other brands' 6201?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 6201 is dimensionally interchangeable with other brands' 6201 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 6201-ZZ and 6201-2RS?
6201-ZZ has metal shields, both sides: Non-contact steel shields. Low friction; keeps out larger particles. 6201-2RS 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 6201?
In the ENRO range, 6701 (12 × 18 × 4 mm), 6801 (12 × 21 × 5 mm), 6901 (12 × 24 × 6 mm), 16001 (12 × 28 × 7 mm) share the 12 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 6201?
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 6201?
Deep Groove Ball Bearings are classified under HS Code 8482.10. Confirm the code with your customs broker.
