H 3156 · shaft 260 mm
Adapter sleeve H 3156: shaft diameter 260 mm, bearing bore 280 mm, width 195 mm. Used with lock nut HM56T and lock washer MB56.
H 3156 set weight (incl. lock nut and lock washer): ≈ 26 kg
Withdrawal sleeve AH 3156G: shaft diameter 260 mm, width 175 mm.
AH 3156G weight: ≈ 14 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: 22256 K.
