23156 Spherical Roller Bearing Dimensions

• The 23156 is the fifteenth of twenty-six sizes ENRO lists in the 23100 series, 280 × 460 × 146 mm.
• Next size down, the 23152, is 260 × 440 × 144 mm: twenty millimetres less bore, twenty millimetres less outside diameter, two millimetres narrower.
• Next size up, the 23160, is 300 × 500 × 160 mm: twenty millimetres more bore, 40 mm more outside diameter, fourteen millimetres wider.
• Seven other ENRO spherical roller bearings share the 280 mm bore: the 24056 (24000 series) is 420 × 140 mm, 40 mm less outside diameter and six millimetres narrower; the 22256 (22200 series) is 500 × 130 mm, 40 mm more outside diameter and sixteen millimetres narrower.
• The 23156 has a radial section of 90 mm ((D − d) / 2) on a 146 mm width, so its cross-section is wider than it is tall.
• Catalog reference values for the 23156: Cr 2650 kN, C0r 4250 kN, limiting speed 1,000 rpm with grease, 1,300 rpm with oil, weight 97.0 kg.
• Catalog dynamic load rating Cr is 2650 kN for the 23156 against 2550 kN for the 23152 (slightly less, 100 kN or 4%) and 3200 kN for the 23160 (noticeably more, 550 kN or 21%).
• ENRO lists the 23156 in two versions: 23156W33, 23156K/W33. In the same series, the 23152 is listed in the same two versions; the 23160 is listed in the same two versions.
