About the 23900 series
- Against the 24000 series, which shares eighteen bore sizes, the 24000 outside diameter is larger and the width larger at each shared bore: at d 340 mm the 23968 is 460 × 90 mm and the 24068 is 520 × 180 mm.
- Against the 23200 series, which shares eighteen bore sizes, the 23200 outside diameter is larger and the width larger at each shared bore: at d 340 mm the 23968 is 460 × 90 mm and the 23268 is 620 × 224 mm.
- Catalog dynamic load ratings Cr run from 414 kN (23938) to 2900 kN (23996).
- Versions in the 23900 series: W33 on every size, K/W33 on every size.
