Three checks for the 24072
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 24072 is 360 × 540 × 180 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 2 versions: 24072W33, 24072K30/W33. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 3550 kN, C0r 6550 kN (catalog reference values). Check the life at your load and speed.

What “24072” means
- 240 — bearing type and dimension series code.
- 72 — bore code: code 72 × 5 = 360 mm.
24072 variants: 24072W33 / 24072K30/W33
| Order as | Meaning |
|---|---|
| 24072W33 | Lubrication groove and holes. Groove and holes in the outer ring for relubrication. |
| 24072K30/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 24072
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 24072 is the twenty-first of twenty-eight sizes ENRO lists in the 24000 series, 360 × 540 × 180 mm.
- Next size down, the 24068, is 340 × 520 × 180 mm: twenty millimetres less bore, twenty millimetres less outside diameter, the same width.
- Next size up, the 24076, is 380 × 560 × 180 mm: twenty millimetres more bore, twenty millimetres more outside diameter, the same width.
- Six other ENRO spherical roller bearings share the 360 mm bore: the 23972 (23900 series) is 480 × 90 mm, 60 mm less outside diameter and 90 mm narrower; the 23172 (23100 series) is 600 × 192 mm, 60 mm more outside diameter and twelve millimetres wider.
- The 24072 has a radial section of 90 mm ((D − d) / 2) on a 180 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 24072: Cr 3550 kN, C0r 6550 kN, limiting speed 700 rpm with grease, 1,000 rpm with oil, weight 145 kg.
- Catalog dynamic load rating Cr is 3550 kN for the 24072 against 3450 kN for the 24068 (slightly less, 100 kN or 3%) and 3600 kN for the 24076 (marginally more, 50 kN or 1%).
- ENRO lists the 24072 in two versions: 24072W33, 24072K30/W33. In the same series, the 24068 is listed in the same two versions; the 24076 is listed in the same two versions.

24072 FAQ
What are the dimensions of the 24072 spherical roller bearing?
The 24072 has a bore (d) of 360 mm, an outside diameter (D) of 540 mm and a width (B) of 180 mm. Minimum chamfer r is 5 mm.
What load rating does the 24072 have?
Catalog reference values: basic dynamic load rating Cr 3550 kN, static rating C0r 6550 kN, limiting speed 700 rpm with grease. Values are confirmed per batch on request.
Which versions of the 24072 can I order?
ENRO lists the 24072 as 24072W33 (Lubrication groove and holes), 24072K30/W33 (Tapered bore 1:30 + Lubrication groove and holes). State the clearance group you need in your RFQ.
Is the ENRO 24072 interchangeable with other brands' 24072?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 24072 is dimensionally interchangeable with other brands' 24072 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 24072?
In the ENRO range, 23972 (360 × 480 × 90 mm), 23072 (360 × 540 × 134 mm), 23172 (360 × 600 × 192 mm), 24172 (360 × 600 × 243 mm) share the 360 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 24072?
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.
