Three checks for the 23176
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 23176 is 380 × 620 × 194 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 2 versions: 23176W33, 23176K/W33. Match the seals, shields or bore type of the old bearing.

Selection notes for the 23176
How this size sits against its neighbours in the 23100 series and the other spherical roller bearing series with the same bore. Every figure is from the ENRO model table.
- The 23176 is the twentieth of twenty-six sizes ENRO lists in the 23100 series, 380 × 620 × 194 mm.
- Next size down, the 23172, is 360 × 600 × 192 mm: twenty millimetres less bore, twenty millimetres less outside diameter, two millimetres narrower.
- Next size up, the 23180, is 400 × 650 × 200 mm: twenty millimetres more bore, 30 mm more outside diameter, six millimetres wider.
- Five other ENRO spherical roller bearings share the 380 mm bore: the 24076 (24000 series) is 560 × 180 mm, 60 mm less outside diameter and fourteen millimetres narrower; the 23276 (23200 series) is 680 × 240 mm, 60 mm more outside diameter and 46 mm wider.
- The 23176 has a radial section of 120 mm ((D − d) / 2) on a 194 mm width, so its cross-section is wider than it is tall.
- ENRO lists the 23176 in two versions: 23176W33, 23176K/W33. In the same series, the 23172 is listed in the same two versions; the 23180 is listed in the same two versions.

Is the ENRO 23176 interchangeable with other brands' 23176?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 23176 is dimensionally interchangeable with other brands' 23176 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 23176?
In the ENRO range, 23976 (380 × 520 × 106 mm), 23076 (380 × 560 × 135 mm), 24076 (380 × 560 × 180 mm), 24176 (380 × 620 × 243 mm) share the 380 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 23176?
