24122 Spherical Roller Bearing Dimensions

• The 24122 is the second of twenty-six sizes ENRO lists in the 24100 series, 110 × 180 × 69 mm.
• Next size down, the 24120, is 100 × 165 × 65 mm: ten millimetres less bore, fifteen millimetres less outside diameter, four millimetres narrower.
• Next size up, the 24124, is 120 × 200 × 80 mm: ten millimetres more bore, twenty millimetres more outside diameter, eleven millimetres wider.
• Six other ENRO spherical roller bearings share the 110 mm bore: the 24022 (24000 series) is 170 × 60 mm, ten millimetres less outside diameter and nine millimetres narrower; the 23222 (23200 series) is 200 × 69.8 mm, twenty millimetres more outside diameter and 0.8 mm wider.
• The 24122 has a radial section of 35 mm ((D − d) / 2) on a 69 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 24122: Cr 520 kN, C0r 750 kN, limiting speed 2,200 rpm with grease, 3,000 rpm with oil, weight 7.10 kg.
• Catalog dynamic load rating Cr is 520 kN for the 24122 against 455 kN for the 24120 (noticeably less, 65 kN or 13%) and 655 kN for the 24124 (substantially more, 135 kN or 26%).
• ENRO lists the 24122 in two versions: 24122W33, 24122K30/W33. In the same series, the 24120 is listed in the same two versions; the 24124 is listed in the same two versions.
