6006 Bearing Dimensions
The ENRO 6006 is a deep groove ball bearing in the 6000 series, 30 × 55 × 13 mm. Boundary dimensions follow the ISO 15 dimension series.
Three checks for the 6006
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 6006 is 30 × 55 × 13 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 4 versions: 6006, 6006-ZZ, 6006-2RS, 6006-NR. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 11.88 kN, C0r 7.97 kN (catalog reference values). Check the life at your load and speed.

What “6006” means
- 60 — bearing type and dimension series code.
- 06 — bore code: code 06 × 5 = 30 mm.
6006 variants: 6006 / 6006-ZZ / 6006-2RS / 6006-NR
| Order as | Meaning |
|---|---|
| 6006 | Open. No shields or seals. Lubricated in service by grease or oil. |
| 6006-ZZ | Metal shields, both sides. Non-contact steel shields. Low friction; keeps out larger particles. |
| 6006-2RS | Rubber seals, both sides. Contact rubber seals. Better protection against dust and water; slightly higher friction. |
| 6006-NR | Snap ring groove with snap ring. Snap ring on the outer ring for axial location in the housing. |

Selection notes for the 6006
How this size sits against its neighbours in the 6000 series and the other deep groove ball bearing series with the same bore. Every figure is from the ENRO model table.
- The 6006 is the ninth of thirty-one sizes ENRO lists in the 6000 series, 30 × 55 × 13 mm.
- Next size down, the 60/28, is 28 × 52 × 12 mm: two millimetres less bore, three millimetres less outside diameter, one millimetre narrower.
- Next size up, the 60/32, is 32 × 58 × 13 mm: two millimetres more bore, three millimetres more outside diameter, the same width.
- Seven other ENRO deep groove ball bearings share the 30 mm bore: the 6906 (6900 series) is 47 × 9 mm, eight millimetres less outside diameter and four millimetres narrower; the 6206 (6200 series) is 62 × 16 mm, seven millimetres more outside diameter and three millimetres wider.
- The 6006 has a radial section of 12.5 mm ((D − d) / 2) on a 13 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 6006: Cr 11.88 kN, C0r 7.97 kN, limiting speed 12,000 rpm with grease, 14,000 rpm with oil, weight 0.116 kg.
- Catalog dynamic load rating Cr is 11.88 kN for the 6006 against 11.25 kN for the 60/28 (slightly less, 0.63 kN or 5%) and 13.59 kN for the 60/32 (noticeably more, 1.71 kN or 14%).
- ENRO lists the 6006 in four versions: 6006, 6006-ZZ, 6006-2RS, 6006-NR. In the same series, the 60/28 is listed in the same four versions; the 60/32 is listed without snap ring groove with snap ring.

Is the ENRO 6006 interchangeable with other brands' 6006?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 6006 is dimensionally interchangeable with other brands' 6006 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 6006-ZZ and 6006-2RS?
6006-ZZ has metal shields, both sides: Non-contact steel shields. Low friction; keeps out larger particles. 6006-2RS 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 6006?
In the ENRO range, 6706 (30 × 37 × 4 mm), 6806 (30 × 42 × 7 mm), 6906 (30 × 47 × 9 mm), 16006 (30 × 55 × 9 mm) share the 30 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 6006?
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 6006?
Deep Groove Ball Bearings are classified under HS Code 8482.10. Confirm the code with your customs broker.
