Abstract: A damper roller system is provided. The system includes an external rotating element connected to a bearing housing. The bearing housing is filled with a viscous fluid and includes at least one bearing element immersed in the viscous fluid. The bearing housing is connected to at least one sealing element sealing the viscous fluid inside the bearing housing. The bearing element is connected to a non-rotating shaft having opposite first and second ends. The shaft is held in place at the first end by the bearing element and is rigidly connectable at the second end to an object. The first end is nail-shaped and immersed in the viscous fluid. A rotation of the external rotating element drives a common rotation of the bearing housing and of the bearing element, and shears the viscous fluid, causing a damping motion proportional to a rotational speed of the external rotating element.
