23188 Spherical Roller Bearing Dimensions

• The 23188 is the twenty-third of twenty-six sizes ENRO lists in the 23100 series, 440 × 720 × 226 mm.
• Next size down, the 23184, is 420 × 700 × 224 mm: twenty millimetres less bore, twenty millimetres less outside diameter, two millimetres narrower.
• Next size up, the 23192, is 460 × 760 × 240 mm: twenty millimetres more bore, 40 mm more outside diameter, fourteen millimetres wider.
• Five other ENRO spherical roller bearings share the 440 mm bore: the 24088 (24000 series) is 650 × 212 mm, 70 mm less outside diameter and fourteen millimetres narrower; the 23288 (23200 series) is 790 × 280 mm, 70 mm more outside diameter and 54 mm wider.
• The 23188 has a radial section of 140 mm ((D − d) / 2) on a 226 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 23188: Cr 6000 kN, C0r 10000 kN, limiting speed 450 rpm with grease, 850 rpm with oil, weight 360 kg.
• Catalog dynamic load rating Cr is 6000 kN for the 23188 against 5600 kN for the 23184 (slightly less, 400 kN or 7%) and 6400 kN for the 23192 (slightly more, 400 kN or 7%).
• ENRO lists the 23188 in two versions: 23188W33, 23188K/W33. In the same series, the 23184 is listed in the same two versions; the 23192 is listed in the same two versions.
