Abstract
A bearing arrangement of a shaft (2) is provided with which an annular bearing sleeve (4) is applied onto the shaft (2). At least in the axial region in which the bearing sleeve (4) is arranged, the shaft (2) includes a profiling extending parallel to its longitudinal axis (X). A corresponding engagement element (12) on the inner periphery of the bearing element (4) engages the profiling with a positive fit. At least one engagement element (12) extends in the direction of the longitudinal axis (X) of the shaft (2) only over a part of the length of the bearing sleeve (4).

A bearing arrangement for a shaft (2), comprising:
- an annular bearing sleeve (4) applied onto the shaft (2), the bearing sleeve (4) being made of a bearing material, the shaft (2) having a profiling extending parallel to a longitudinal axis (X) of the shaft at least in an axial region on which the bearing sleeve (4) is applied,
- at least one engagement element (12) on an inner periphery of the bearing sleeve (4) corresponding with and engaging into the profiling with a positive fit, wherein the at least one engagement element (12) extends in a direction of the longitudinal axis (X) of the shaft (2) only over a part of a length of the bearing sleeve (4) and is spaced from axial ends (8, 10) of the bearing sleeve (4) in the direction of the longitudinal axis (X), and
- a retaining sleeve (6) applied onto the shaft (2) and bearing upon at least one of the axial ends (8, 10) of the bearing sleeve (4) for axial fixation of the bearing sleeve (4) along the longitudinal axis (X).
