H 2356 · shaft 260 mm
Adapter sleeve H 2356: shaft diameter 260 mm, bearing bore 280 mm, width 224 mm. Used with lock nut HM56T and lock washer MB56.
H 2356 set weight (incl. lock nut and lock washer): ≈ 29 kg
A sleeve mounts a tapered-bore bearing on a plain cylindrical shaft and bridges the difference between the bearing bore and the shaft diameter.
Use with a sleeve requires the tapered-bore version of the bearing: 23256 K.
