Before you order

Three checks for the 23948

Most wrong replacements come from one of these. Each answer below comes from the ENRO model table.

01 · Size

Does the size match?

Measure bore, outside diameter and width. The 23948 is 240 × 320 × 60 mm. If one value differs, see the adjacent sizes below.

02 · Version

Which version do you need?

ENRO lists 2 versions: 23948W33, 23948K/W33. Match the seals, shields or bore type of the old bearing.

Versions table →
03 · Load

Is the load rating enough?

Cr 564 kN, C0r 1160 kN (catalog reference values). Check the life at your load and speed.

Reading the number

What “23948” means

  • 239 — bearing type and dimension series code.
  • 48 — bore code: code 48 × 5 = 240 mm.

23948 variants: 23948W33 / 23948K/W33

Order asMeaning
23948W33Lubrication groove and holes. Groove and holes in the outer ring for relubrication.

Selection notes for the 23948

How this size sits against its neighbours in the 23900 series and the other spherical roller bearing series with the same bore. Every figure is from the ENRO model table.

  • The 23948 is the fifth of eighteen sizes ENRO lists in the 23900 series, 240 × 320 × 60 mm.
  • Next size down, the 23944, is 220 × 300 × 60 mm: twenty millimetres less bore, twenty millimetres less outside diameter, the same width.
  • Next size up, the 23952, is 260 × 360 × 75 mm: twenty millimetres more bore, 40 mm more outside diameter, fifteen millimetres wider.
  • Seven other ENRO spherical roller bearings share the 240 mm bore: the 23048 (23000 series) is 360 × 92 mm, 40 mm more outside diameter and 32 mm wider.
  • The 23948 has a radial section of 40 mm ((D − d) / 2) on a 60 mm width, so its cross-section is wider than it is tall.
  • Catalog reference values for the 23948: Cr 564 kN, C0r 1160 kN, limiting speed 1,700 rpm with grease, 2,000 rpm with oil, weight 13.5 kg.
  • Catalog dynamic load rating Cr is 564 kN for the 23948 against 546 kN for the 23944 (slightly less, 18 kN or 3%) and 880 kN for the 23952 (substantially more, 316 kN or 56%).
  • ENRO lists the 23948 in two versions: 23948W33, 23948K/W33. In the same series, the 23944 is listed in the same two versions; the 23952 is listed in the same two versions.

FAQ

23948 FAQ

What are the dimensions of the 23948 spherical roller bearing?

The 23948 has a bore (d) of 240 mm, an outside diameter (D) of 320 mm and a width (B) of 60 mm. Minimum chamfer r is 2.1 mm.

What load rating does the 23948 have?

Catalog reference values: basic dynamic load rating Cr 564 kN, static rating C0r 1160 kN, limiting speed 1,700 rpm with grease. Values are confirmed per batch on request.

Which versions of the 23948 can I order?

ENRO lists the 23948 as 23948W33 (Lubrication groove and holes), 23948K/W33 (Tapered bore 1:12 + Lubrication groove and holes). State the clearance group you need in your RFQ.

Is the ENRO 23948 interchangeable with other brands' 23948?

Boundary dimensions follow the ISO 15 dimension series. The ENRO 23948 is dimensionally interchangeable with other brands' 23948 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 23948?

In the ENRO range, 23048 (240 × 360 × 92 mm), 24048 (240 × 360 × 118 mm), 23148 (240 × 400 × 128 mm), 24148 (240 × 400 × 160 mm) share the 240 mm bore. Outside diameter and width differ, so check the housing before switching.

Which clearance group should I order for the 23948?

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.
