Disclosed is a motor-operated conveyer roller for conveyor systems, having a roller body, a drive device arranged inside an interior space of the roller body, and a coupling device designed to transmit a torque from the drive device to an inner peripheral surface of the interior space of the roller body, wherein said coupling device has a clamping bushing, a clamping ring which can move axially with respect to the clamping bushing, a fastener element for the purpose of holding a clamping ring in a tensioned position against the clamping bushing, and a thrust collar which is fixed between a contact surface of the clamping bushing and a contact surface of the clamping ring in the tensioned position, wherein the thrust collar is frictionally connected via its outer periphery to the inner peripheral surface of the interior space of the roller body in the tensioned position. |
