摘要： A roller head for a planetary rolling arrangement, said roller head comprising a housing, inside which housing there is rotatably arranged a hollow outer axis and means for rotating said outer axis, as well as inside said outer axis, in a manner that transmits the rotary motion thereof, a center axis which is movable in the axial direction and can be locked in the axial direction, said center axis being provided with a roller. The roller head is characterized by an adjusting axis which is rotatably arranged at the end of the outer axis that is located on the opposite side with respect to the roller and is essentially locked in the axial direction said adjusting axis comprising a counterpart for the threaded section provided in the center axis, and said adjusting axis also including a locking member, which in the locking position forms a friction coupling at least between the adjusting axis and the outer axis.
