Abstract: Linear guide system has a guide element and one or more rotating bodies, movable according to a linear motion along the guide element and constrained to a structure to be supported and moved along the guide element. Each rotating body has at least one roller with an outer ring resting on a contact surface of the guide element, and at least one substantially cylindrical stem. At least one safety supporting device is connected to a structure to be supported and the one or more relating bodies. Under the normal load conditions of the linear guide system, the safety supporting device allows for the normal linear motion of the rollers along the contact surface. When load higher than a given threshold is applied on the linear guide system, the safety supporting device rests on the contact surface, discharging the load there.
