23228 Spherical Roller Bearing Dimensions

• The 23228 is the sixth of twenty-seven sizes ENRO lists in the 23200 series, 140 × 250 × 88 mm.
• Next size down, the 23226, is 130 × 230 × 80 mm: ten millimetres less bore, twenty millimetres less outside diameter, eight millimetres narrower.
• Next size up, the 23230, is 150 × 270 × 96 mm: ten millimetres more bore, twenty millimetres more outside diameter, eight millimetres wider.
• Six other ENRO spherical roller bearings share the 140 mm bore: the 24128 (24100 series) is 225 × 85 mm, 25 mm less outside diameter and three millimetres narrower; the 22328 (22300 series) is 300 × 102 mm, 50 mm more outside diameter and fourteen millimetres wider.
• The 23228 has a radial section of 55 mm ((D − d) / 2) on a 88 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 23228: Cr 915 kN, C0r 1250 kN, limiting speed 1,700 rpm with grease, 2,400 rpm with oil, weight 19.00 kg.
• Catalog dynamic load rating Cr is 915 kN for the 23228 against 780 kN for the 23226 (noticeably less, 135 kN or 15%) and 1080 kN for the 23230 (noticeably more, 165 kN or 18%).
• ENRO lists the 23228 in two versions: 23228W33, 23228K/W33. In the same series, the 23226 is listed in the same two versions; the 23230 is listed in the same two versions.
