22240 Spherical Roller Bearing Dimensions

• The 22240 is the twenty-sixth of thirty-three sizes ENRO lists in the 22200 series, 200 × 360 × 98 mm.
• Next size down, the 22238, is 190 × 340 × 92 mm: ten millimetres less bore, twenty millimetres less outside diameter, six millimetres narrower.
• Next size up, the 22244, is 220 × 400 × 108 mm: twenty millimetres more bore, 40 mm more outside diameter, ten millimetres wider.
• Seven other ENRO spherical roller bearings share the 200 mm bore: the 23140 (23100 series) is 340 × 112 mm, twenty millimetres less outside diameter and fourteen millimetres wider; the 22340 (22300 series) is 420 × 138 mm, 60 mm more outside diameter and 40 mm wider.
• The 22240 has a radial section of 80 mm ((D − d) / 2) on a 98 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 22240: Cr 1460 kN, C0r 1930 kN, limiting speed 1,600 rpm with grease, 2,200 rpm with oil, weight 43.5 kg.
• Catalog dynamic load rating Cr is 1460 kN for the 22240 against 1270 kN for the 22238 (noticeably less, 190 kN or 13%) and 1760 kN for the 22244 (noticeably more, 300 kN or 21%).
• ENRO lists the 22240 in two versions: 22240W33, 22240K/W33. In the same series, the 22238 is listed in the same two versions; the 22244 is listed in the same two versions.
