Three checks for the 6917
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 6917 is 85 × 120 × 18 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 3 versions: 6917, 6917-ZZ, 6917-2RS. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 28.80 kN, C0r 28.42 kN (catalog reference values). Check the life at your load and speed.

What “6917” means
- 69 — bearing type and dimension series code.
- 17 — bore code: code 17 × 5 = 85 mm.
6917 variants: 6917 / 6917-ZZ / 6917-2RS
| Order as | Meaning |
|---|---|
| 6917 | Open. No shields or seals. Lubricated in service by grease or oil. |
| 6917-ZZ | Metal shields, both sides. Non-contact steel shields. Low friction; keeps out larger particles. |
| 6917-2RS | Rubber seals, both sides. Contact rubber seals. Better protection against dust and water; slightly higher friction. |

Selection notes for the 6917
How this size sits against its neighbours in the 6900 series and the other deep groove ball bearing series with the same bore. Every figure is from the ENRO model table.
- The 6917 is the eighteenth of twenty-eight sizes ENRO lists in the 6900 series, 85 × 120 × 18 mm.
- Next size down, the 6916, is 80 × 110 × 16 mm: five millimetres less bore, ten millimetres less outside diameter, two millimetres narrower.
- Next size up, the 6918, is 90 × 125 × 18 mm: five millimetres more bore, five millimetres more outside diameter, the same width.
- Six other ENRO deep groove ball bearings share the 85 mm bore: the 6817 (6800 series) is 110 × 13 mm, ten millimetres less outside diameter and five millimetres narrower; the 16017 (16000 series) is 130 × 14 mm, ten millimetres more outside diameter and four millimetres narrower.
- The 6917 has a radial section of 17.5 mm ((D − d) / 2) on a 18 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 6917: Cr 28.80 kN, C0r 28.42 kN, limiting speed 5,100 rpm with grease, 6,000 rpm with oil, weight 0.550 kg.
- Catalog dynamic load rating Cr is 28.80 kN for the 6917 against 22.41 kN for the 6916 (noticeably less, 6.39 kN or 22%) and 29.70 kN for the 6918 (slightly more, 0.9 kN or 3%).
- ENRO lists the 6917 in three versions: 6917, 6917-ZZ, 6917-2RS. In the same series, the 6916 is listed in the same three versions; the 6918 is listed in the same three versions.

Which versions of the 6917 can I order?
ENRO lists the 6917 as 6917 (Open), 6917-ZZ (Metal shields, both sides), 6917-2RS (Rubber seals, both sides). State the clearance group you need in your RFQ.
Is the ENRO 6917 interchangeable with other brands' 6917?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 6917 is dimensionally interchangeable with other brands' 6917 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 6917-ZZ and 6917-2RS?
6917-ZZ has metal shields, both sides: Non-contact steel shields. Low friction; keeps out larger particles. 6917-2RS 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 6917?
In the ENRO range, 6817 (85 × 110 × 13 mm), 16017 (85 × 130 × 14 mm), 6017 (85 × 130 × 22 mm), 6217 (85 × 150 × 28 mm) share the 85 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 6917?
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 6917?
Deep Groove Ball Bearings are classified under HS Code 8482.10. Confirm the code with your customs broker.
