Three checks for the 6230
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 6230 is 150 × 270 × 45 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 4 versions: 6230, 6230-ZZ, 6230-2RS, 6230-NR. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Catalog ratings for the 6230 are pending confirmation. Send your load and speed with the RFQ.

What “6230” means
- 62 — bearing type and dimension series code.
- 30 — bore code: code 30 × 5 = 150 mm.
6230 variants: 6230 / 6230-ZZ / 6230-2RS / 6230-NR
| Order as | Meaning |
|---|---|
| 6230 | Open. No shields or seals. Lubricated in service by grease or oil. |
| 6230-ZZ | Metal shields, both sides. Non-contact steel shields. Low friction; keeps out larger particles. |
| 6230-2RS | Rubber seals, both sides. Contact rubber seals. Better protection against dust and water; slightly higher friction. |
| 6230-NR | Snap ring groove with snap ring. Snap ring on the outer ring for axial location in the housing. |

Selection notes for the 6230
How this size sits against its neighbours in the 6200 series and the other deep groove ball bearing series with the same bore. Every figure is from the ENRO model table.
- The 6230 is the thirtieth of thirty-one sizes ENRO lists in the 6200 series, 150 × 270 × 45 mm.
- Next size down, the 6228, is 140 × 250 × 42 mm: ten millimetres less bore, twenty millimetres less outside diameter, three millimetres narrower.
- Next size up, the 6232, is 160 × 290 × 48 mm: ten millimetres more bore, twenty millimetres more outside diameter, three millimetres wider.
- Five other ENRO deep groove ball bearings share the 150 mm bore: the 6030 (6000 series) is 225 × 35 mm, 45 mm less outside diameter and ten millimetres narrower; the 6330 (6300 series) is 320 × 65 mm, 50 mm more outside diameter and twenty millimetres wider.
- The 6230 has a radial section of 60 mm ((D − d) / 2) on a 45 mm width, so its cross-section is taller than it is wide.
- ENRO lists the 6230 in four versions: 6230, 6230-ZZ, 6230-2RS, 6230-NR. In the same series, the 6228 is listed in the same four versions; the 6232 is listed in the same four versions.
