A solid bowl centrifuge includes a rotatable drum having a cylindrical portion with length L1 and a conical portion with length L2, which, when added, give the length LT of the drum. A screw is arranged in the drum and is rotatable relative to the rotatable drum with a differential speed. At least two drum bearings for supporting the drum in the housing are spaced apart with a spacing LL. A spacing LL of the drum bearings for supporting the drum relative to one another is less than the length LT of the drum.
