Three checks for the 22330
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 22330 is 150 × 320 × 108 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 2 versions: 22330W33, 22330K/W33. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Catalog ratings for the 22330 are pending confirmation. Send your load and speed with the RFQ.

Selection notes for the 22330
How this size sits against its neighbours in the 22300 series and the other spherical roller bearing series with the same bore. Every figure is from the ENRO model table.
- The 22330 is the eighteenth of twenty-eight sizes ENRO lists in the 22300 series, 150 × 320 × 108 mm.
- Next size down, the 22328, is 140 × 300 × 102 mm: ten millimetres less bore, twenty millimetres less outside diameter, six millimetres narrower.
- Next size up, the 22332, is 160 × 340 × 114 mm: ten millimetres more bore, twenty millimetres more outside diameter, six millimetres wider.
- Six other ENRO spherical roller bearings share the 150 mm bore: the 23230 (23200 series) is 270 × 96 mm, 50 mm less outside diameter and twelve millimetres narrower.
- The 22330 has a radial section of 85 mm ((D − d) / 2) on a 108 mm width, so its cross-section is wider than it is tall.
- ENRO lists the 22330 in two versions: 22330W33, 22330K/W33. In the same series, the 22328 is listed in the same two versions; the 22332 is listed in the same two versions.

What load rating does the 22330 have?
Load ratings, speeds and weight for the 22330 are catalog values pending confirmation. No figure is shown until it is confirmed; ask for the values with your RFQ.
Which versions of the 22330 can I order?
ENRO lists the 22330 as 22330W33 (Lubrication groove and holes), 22330K/W33 (Tapered bore 1:12 + Lubrication groove and holes). State the clearance group you need in your RFQ.
Is the ENRO 22330 interchangeable with other brands' 22330?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 22330 is dimensionally interchangeable with other brands' 22330 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 22330?
In the ENRO range, 23030 (150 × 225 × 56 mm), 24030 (150 × 225 × 75 mm), 23130 (150 × 250 × 80 mm), 24130 (150 × 250 × 100 mm) share the 150 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 22330?
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.
