Sustainable Sliding-Bearing Assembly

A sliding-bearing assembly comprising a slide and a rail, wherein the rail as a cylindrical guide portion, a cylinder axis of which runs in a longitudinal direction, and wherein the slide has a passage running in the longitudinal direction for receiving the guide portion of the rail, wherein in an operating state of the sliding-bearing assembly, in which the slide can be moved such that it is slidably guided along the rail in the longitudinal direction, the guide portion is arranged in the passage of slide and is enclosed by an inner face of the passage, thus fixing the slide perpendicularly to the longitudinal direction, wherein in the operating state, the slide rests against the rail exclusively via the inner face of its passage, so that the inner face of the slide forms the surface of the slide which corresponds to the rail and which rests on the rail during a movement of the slide,

• wherein the guide portion is made of wood and the inner side of the passage is made of a sliding plastic which consists of at least 3 wt. % of lubricants, wherein, in the operating state, the slide can be loaded with a load in a load direction perpendicular to the longitudinal direction, producing a surface pressure between the inner face and the guide portion and, while maintaining the surface pressure in the longitudinal direction relative to the rail, can be moved along the rail in a sliding manner, wherein, in the operating state, the slide
• can be loaded in the load direction with a load producing a value for the surface pressure of 0.4 MPa and, without the addition of external lubricant, can be moved directly bearing against the rail in the longitudinal direction relative to the rail at a speed of 0.1 m/s with a sliding coefficient of friction of less than 0.4,
• can be loaded in the load direction with a load producing a value for the surface pressure 0.2 MPa and, without the addition of external lubricant, can be moved directly bearing against the rail in the longitudinal direction relative to the rail at a speed of 0.3 m/s with a sliding friction coefficient of less than 0.2, and/or
• can be loaded in the load direction with a load producing a value for the surface pressure of 1.0 MPa and, without the addition of external lubricant, can be moved directly bearing against the rail in the longitudinal direction relative to the rail at a speed of 0.2 m/s with a sliding friction coefficient of less than 0.4.
