24024 Spherical Roller Bearing Dimensions
The ENRO 24024 is a spherical roller bearing in the 24000 series, 120 × 180 × 60 mm. Boundary dimensions follow the ISO 15 dimension series.
Three checks for the 24024
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 24024 is 120 × 180 × 60 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 2 versions: 24024W33, 24024K30/W33. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 430 kN, C0r 670 kN (catalog reference values). Check the life at your load and speed.

What “24024” means
- 240 — bearing type and dimension series code.
- 24 — bore code: code 24 × 5 = 120 mm.
24024 variants: 24024W33 / 24024K30/W33
| Order as | Meaning |
|---|---|
| 24024W33 | Lubrication groove and holes. Groove and holes in the outer ring for relubrication. |
| 24024K30/W33 | Tapered bore 1:30 + Lubrication groove and holes. Tapered bore, taper 1:30, used on wide series such as 240 and 241. Groove and holes in the outer ring for relubrication. |

Selection notes for the 24024
How this size sits against its neighbours in the 24000 series and the other spherical roller bearing series with the same bore. Every figure is from the ENRO model table.
- The 24024 is the fifth of twenty-eight sizes ENRO lists in the 24000 series, 120 × 180 × 60 mm.
- Next size down, the 24022, is 110 × 170 × 60 mm: ten millimetres less bore, ten millimetres less outside diameter, the same width.
- Next size up, the 24026, is 130 × 200 × 69 mm: ten millimetres more bore, twenty millimetres more outside diameter, nine millimetres wider.
- Six other ENRO spherical roller bearings share the 120 mm bore: the 23124 (23100 series) is 200 × 62 mm, twenty millimetres more outside diameter and two millimetres wider.
- The 24024 has a radial section of 30 mm ((D − d) / 2) on a 60 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 24024: Cr 430 kN, C0r 670 kN, limiting speed 2,400 rpm with grease, 3,400 rpm with oil, weight 5.45 kg.
- Catalog dynamic load rating Cr is 430 kN for the 24024 against 415 kN for the 24022 (slightly less, 15 kN or 3%) and 540 kN for the 24026 (substantially more, 110 kN or 26%).
- ENRO lists the 24024 in two versions: 24024W33, 24024K30/W33. In the same series, the 24022 is listed in the same two versions; the 24026 is listed in the same two versions.

24024 FAQ
What are the dimensions of the 24024 spherical roller bearing?
The 24024 has a bore (d) of 120 mm, an outside diameter (D) of 180 mm and a width (B) of 60 mm. Minimum chamfer r is 2 mm.
What load rating does the 24024 have?
Catalog reference values: basic dynamic load rating Cr 430 kN, static rating C0r 670 kN, limiting speed 2,400 rpm with grease. Values are confirmed per batch on request.
Which versions of the 24024 can I order?
ENRO lists the 24024 as 24024W33 (Lubrication groove and holes), 24024K30/W33 (Tapered bore 1:30 + Lubrication groove and holes). State the clearance group you need in your RFQ.
Is the ENRO 24024 interchangeable with other brands' 24024?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 24024 is dimensionally interchangeable with other brands' 24024 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.
Which bearings have the same bore as the 24024?
In the ENRO range, 23024 (120 × 180 × 46 mm), 23124 (120 × 200 × 62 mm), 24124 (120 × 200 × 80 mm), 22224 (120 × 215 × 58 mm) share the 120 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 24024?
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.
