Three checks for the 23240
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 23240 is 200 × 360 × 128 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 2 versions: 23240W33, 23240K/W33. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 1860 kN, C0r 2700 kN (catalog reference values). Check the life at your load and speed.

Selection notes for the 23240
How this size sits against its neighbours in the 23200 series and the other spherical roller bearing series with the same bore. Every figure is from the ENRO model table.
- The 23240 is the twelfth of twenty-seven sizes ENRO lists in the 23200 series, 200 × 360 × 128 mm.
- Next size down, the 23238, is 190 × 340 × 120 mm: ten millimetres less bore, twenty millimetres less outside diameter, eight millimetres narrower.
- Next size up, the 23244, is 220 × 400 × 144 mm: twenty millimetres more bore, 40 mm more outside diameter, sixteen millimetres wider.
- Seven other ENRO spherical roller bearings share the 200 mm bore: the 24140 (24100 series) is 340 × 140 mm, twenty millimetres less outside diameter and twelve millimetres wider; the 22340 (22300 series) is 420 × 138 mm, 60 mm more outside diameter and ten millimetres wider.
- The 23240 has a radial section of 80 mm ((D − d) / 2) on a 128 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 23240: Cr 1860 kN, C0r 2700 kN, limiting speed 1,200 rpm with grease, 1,700 rpm with oil, weight 58.0 kg.
- Catalog dynamic load rating Cr is 1860 kN for the 23240 against 1660 kN for the 23238 (noticeably less, 200 kN or 11%) and 2360 kN for the 23244 (substantially more, 500 kN or 27%).
- ENRO lists the 23240 in two versions: 23240W33, 23240K/W33. In the same series, the 23238 is listed in the same two versions; the 23244 is listed in the same two versions.

23240 FAQ
What are the dimensions of the 23240 spherical roller bearing?
The 23240 has a bore (d) of 200 mm, an outside diameter (D) of 360 mm and a width (B) of 128 mm. Minimum chamfer r is 4 mm.
What load rating does the 23240 have?
Catalog reference values: basic dynamic load rating Cr 1860 kN, static rating C0r 2700 kN, limiting speed 1,200 rpm with grease. Values are confirmed per batch on request.
Which versions of the 23240 can I order?
ENRO lists the 23240 as 23240W33 (Lubrication groove and holes), 23240K/W33 (Tapered bore 1:12 + Lubrication groove and holes). State the clearance group you need in your RFQ.
Is the ENRO 23240 interchangeable with other brands' 23240?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 23240 is dimensionally interchangeable with other brands' 23240 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 23240?
In the ENRO range, 23940 (200 × 280 × 60 mm), 23040 (200 × 310 × 82 mm), 24040 (200 × 310 × 109 mm), 23140 (200 × 340 × 112 mm) share the 200 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 23240?
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.
