23144 Spherical Roller Bearing Dimensions

• The 23144 is the twelfth of twenty-six sizes ENRO lists in the 23100 series, 220 × 370 × 120 mm.
• Next size down, the 23140, is 200 × 340 × 112 mm: twenty millimetres less bore, 30 mm less outside diameter, eight millimetres narrower.
• Next size up, the 23148, is 240 × 400 × 128 mm: twenty millimetres more bore, 30 mm more outside diameter, eight millimetres wider.
• Seven other ENRO spherical roller bearings share the 220 mm bore: the 24044 (24000 series) is 340 × 118 mm, 30 mm less outside diameter and two millimetres narrower; the 22244 (22200 series) is 400 × 108 mm, 30 mm more outside diameter and twelve millimetres narrower.
• The 23144 has a radial section of 75 mm ((D − d) / 2) on a 120 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 23144: Cr 1800 kN, C0r 2750 kN, limiting speed 1,300 rpm with grease, 1,700 rpm with oil, weight 53.5 kg.
• Catalog dynamic load rating Cr is 1800 kN for the 23144 against 1600 kN for the 23140 (noticeably less, 200 kN or 11%) and 2080 kN for the 23148 (noticeably more, 280 kN or 16%).
• ENRO lists the 23144 in two versions: 23144W33, 23144K/W33. In the same series, the 23140 is listed in the same two versions; the 23148 is listed in the same two versions.
