Three checks for the 23164
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 23164 is 320 × 540 × 176 mm. If one value differs, see the adjacent sizes below.
Adjacent sizes →Which version do you need?
ENRO lists 2 versions: 23164W33, 23164K/W33. Match the seals, shields or bore type of the old bearing.
Versions table →Is the load rating enough?
Cr 3750 kN, C0r 6000 kN (catalog reference values). Check the life at your load and speed.

Selection notes for the 23164
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 23164 is the seventeenth of twenty-six sizes ENRO lists in the 23100 series, 320 × 540 × 176 mm.
- Next size down, the 23160, is 300 × 500 × 160 mm: twenty millimetres less bore, 40 mm less outside diameter, sixteen millimetres narrower.
- Next size up, the 23168, is 340 × 580 × 190 mm: twenty millimetres more bore, 40 mm more outside diameter, fourteen millimetres wider.
- Six other ENRO spherical roller bearings share the 320 mm bore: the 24064 (24000 series) is 480 × 160 mm, 60 mm less outside diameter and sixteen millimetres narrower; the 22264 (22200 series) is 580 × 150 mm, 40 mm more outside diameter and 26 mm narrower.
- The 23164 has a radial section of 110 mm ((D − d) / 2) on a 176 mm width, so its cross-section is wider than it is tall.
- Catalog reference values for the 23164: Cr 3750 kN, C0r 6000 kN, limiting speed 850 rpm with grease, 1,100 rpm with oil, weight 165.0 kg.
- Catalog dynamic load rating Cr is 3750 kN for the 23164 against 3200 kN for the 23160 (noticeably less, 550 kN or 15%) and 4250 kN for the 23168 (noticeably more, 500 kN or 13%).
- ENRO lists the 23164 in two versions: 23164W33, 23164K/W33. In the same series, the 23160 is listed in the same two versions; the 23168 is listed in the same two versions.

23164 FAQ
What are the dimensions of the 23164 spherical roller bearing?
The 23164 has a bore (d) of 320 mm, an outside diameter (D) of 540 mm and a width (B) of 176 mm. Minimum chamfer r is 5 mm.
What load rating does the 23164 have?
Catalog reference values: basic dynamic load rating Cr 3750 kN, static rating C0r 6000 kN, limiting speed 850 rpm with grease. Values are confirmed per batch on request.
Which versions of the 23164 can I order?
ENRO lists the 23164 as 23164W33 (Lubrication groove and holes), 23164K/W33 (Tapered bore 1:12 + Lubrication groove and holes). State the clearance group you need in your RFQ.
Is the ENRO 23164 interchangeable with other brands' 23164?
Boundary dimensions follow the ISO 15 dimension series. The ENRO 23164 is dimensionally interchangeable with other brands' 23164 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 23164?
In the ENRO range, 23964 (320 × 440 × 90 mm), 23064 (320 × 480 × 121 mm), 24064 (320 × 480 × 160 mm), 24164 (320 × 540 × 218 mm) share the 320 mm bore. Outside diameter and width differ, so check the housing before switching.
Which clearance group should I order for the 23164?
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.
