The invention relates to a bearing arrangement (12) for a part to be mounted such that the part rotates about an axis, such as a cylinder, roller, drum or shaft, comprising at least one rolling bearing (23), which is accommodated in a bearing housing (27), which is mounted movably in an arrangement housing (29) in a linearly movable manner by at least one linear guide (28), and also including an actuation device (1) for effecting a linear shifting movement of the bearing housing perpendicularly to the axis between a rest position and a working position. The actuation device includes at least one prestressed spring element, which presses the bearing housing into the working position, and at least one hydraulic or pneumatic device for generating a restoring force acting counter to the spring element for moving the bearing housing into the rest position.
