摘要：
Disclosed is a bearing arrangement in an actuator of a forest machine. The bearing arrangement comprises a tubular frame (110) of the actuator of the forest machine, having a first opening (112). The bearing arrangement also comprises a bushing (120), at least partially being arranged in the first opening, and having a second opening (122). The bushing comprises a flange (126) protruding from a frame of the bushing, which acts as a motion surface against an end surface of the tubular frame. At least part of an axle (130) and/or at least part of a bearing (140) are arranged in the second opening. The axle or bearing are arranged stationary or movable in relation to the bushing. The flange is one and a half times thicker than the wall thickness of the frame of the bushing. This advantageously provides greater rigidity, which allows the flange to bear greater force in the direction of the axle and provides greater resistance to bending. The bushing is removable from the frame of the actuator of the forest machine for ease of replacement, when worn. Further, a method for maintaining an actuator of a forest machine is also disclosed, which at least includes the steps of removing a worn bushing from first opening in a frame of a forest machine and installing a replacement bushing in the first opening.
