22230 Spherical Roller Bearing Dimensions

• The 22230 is the twenty-first of thirty-three sizes ENRO lists in the 22200 series, 150 × 270 × 73 mm.
• Next size down, the 22228, is 140 × 250 × 68 mm: ten millimetres less bore, twenty millimetres less outside diameter, five millimetres narrower.
• Next size up, the 22232, is 160 × 290 × 80 mm: ten millimetres more bore, twenty millimetres more outside diameter, seven millimetres wider.
• Six other ENRO spherical roller bearings share the 150 mm bore: the 23130 (23100 series) is 250 × 80 mm, twenty millimetres less outside diameter and seven millimetres wider; the 22330 (22300 series) is 320 × 108 mm, 50 mm more outside diameter and 35 mm wider.
• The 22230 has a radial section of 60 mm ((D − d) / 2) on a 73 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 22230: Cr 850 kN, C0r 1080 kN, limiting speed 2,200 rpm with grease, 3,000 rpm with oil, weight 18.00 kg.
• Catalog dynamic load rating Cr is 850 kN for the 22230 against 710 kN for the 22228 (noticeably less, 140 kN or 16%) and 1000 kN for the 22232 (noticeably more, 150 kN or 18%).
• ENRO lists the 22230 in two versions: 22230W33, 22230K/W33. In the same series, the 22228 is listed in the same two versions; the 22232 is listed in the same two versions.
