  • the devices for pre-positioning the cylinder sleeve can radially to the carrier body over its entire axial length extend. But they can also be divided into individual sections via the axial Length of the carrier body or the sleeve-shaped element can be provided.
  • Simplifying the assembly or replacement of a cylinder body can be achieved in that the devices for prepositioning the Cylinder sleeve are provided parallel to the axis of rotation of the carrier body. So centering of the lateral surface can already be carried out as part of the pre-positioning achieve the cylinder sleeve, the final centering by a Prestressing the bevels provided on the end faces provided centering surfaces; one final to increase accuracy Centering can also be done by lateral bracing of the end faces against each other.
  • the devices for prepositioning can of the cylinder sleeve make a frictional contact with the inner wall of the cylinder sleeve.
  • their entire scope would be supporting devices for prepositioning also conceivable a positive connection between the end regions of the essentially radially extending devices for prepositioning the Cylinder sleeve and the inner wall of the cylinder sleeve in the form of along extending recesses, for example in the form of longitudinal grooves produce.
