Three checks for the 23296
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 23296 is 480 × 870 × 310 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 2 versions: 23296W33, 23296K/W33. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 8300 kN, C0r 15000 kN (catalog reference values). Check the life at your load and speed.

Selection notes for the 23296
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 23296 is the twenty-sixth of twenty-seven sizes ENRO lists in the 23200 series, 480 × 870 × 310 mm.
- Next size down, the 23292, is 460 × 830 × 296 mm: twenty millimetres less bore, 40 mm less outside diameter, fourteen millimetres narrower.
- Next size up, the 232/500, is 500 × 920 × 336 mm: twenty millimetres more bore, 50 mm more outside diameter, 26 mm wider.
- Six other ENRO spherical roller bearings share the 480 mm bore: the 24196 (24100 series) is 790 × 308 mm, 80 mm less outside diameter and two millimetres narrower.
- The 23296 has a radial section of 195 mm ((D − d) / 2) on a 310 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 23296: Cr 8300 kN, C0r 15000 kN, limiting speed 380 rpm with grease, 530 rpm with oil, weight 800.0 kg.
- Catalog dynamic load rating Cr is 8300 kN for the 23296 against 8500 kN for the 23292 (marginally more, 200 kN or 2%) and 10500 kN for the 232/500 (substantially more, 2200 kN or 27%).
- ENRO lists the 23296 in two versions: 23296W33, 23296K/W33. In the same series, the 23292 is listed in the same two versions; the 232/500 is listed in the same two versions.

23296 FAQ
What are the dimensions of the 23296 spherical roller bearing?
The 23296 has a bore (d) of 480 mm, an outside diameter (D) of 870 mm and a width (B) of 310 mm. Minimum chamfer r is 7.5 mm.
What load rating does the 23296 have?
Catalog reference values: basic dynamic load rating Cr 8300 kN, static rating C0r 15000 kN, limiting speed 380 rpm with grease. Values are confirmed per batch on request.
Which versions of the 23296 can I order?
ENRO lists the 23296 as 23296W33 (Lubrication groove and holes), 23296K/W33 (Tapered bore 1:12 + Lubrication groove and holes). State the clearance group you need in your RFQ.
Is the ENRO 23296 interchangeable with other brands' 23296?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 23296 is dimensionally interchangeable with other brands' 23296 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 23296?
In the ENRO range, 23896 (480 × 600 × 90 mm), 23996 (480 × 650 × 128 mm), 23096 (480 × 700 × 165 mm), 24096 (480 × 700 × 218 mm) share the 480 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 23296?
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.
