24080 Spherical Roller Bearing Dimensions

• The 24080 is the twenty-third of twenty-eight sizes ENRO lists in the 24000 series, 400 × 600 × 200 mm.
• Next size down, the 24076, is 380 × 560 × 180 mm: twenty millimetres less bore, 40 mm less outside diameter, twenty millimetres narrower.
• Next size up, the 24084, is 420 × 620 × 200 mm: twenty millimetres more bore, twenty millimetres more outside diameter, the same width.
• Six other ENRO spherical roller bearings share the 400 mm bore: the 23980 (23900 series) is 540 × 106 mm, 60 mm less outside diameter and 94 mm narrower; the 23180 (23100 series) is 650 × 200 mm, 50 mm more outside diameter and the same width.
• The 24080 has a radial section of 100 mm ((D − d) / 2) on a 200 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 24080: Cr 4300 kN, C0r 8000 kN, limiting speed 630 rpm with grease, 900 rpm with oil, weight 205 kg.
• Catalog dynamic load rating Cr is 4300 kN for the 24080 against 3600 kN for the 24076 (noticeably less, 700 kN or 16%) and 4400 kN for the 24084 (marginally more, 100 kN or 2%).
• ENRO lists the 24080 in two versions: 24080W33, 24080K30/W33. In the same series, the 24076 is listed in the same two versions; the 24084 is listed in the same two versions.
