ROLLED-UP PLAIN BEARING BUSH

摘要

The invention relates to a rolled-up plain bearing bush made from a metal/plastic composite plain bearing material whose wall has a thickness of at least 0.75 mm and which can be pressed into an opening of said bearing to form a medium-force fit. The inventive bearing bush also comprises a metal supporting layer and a sliding layer. In order to reduce weight and corrosion, the plain bearing bush is characterized in that the metal supporting layer is made of an aluminum alloy and the sliding layer consists of an expanded aluminum metal alloy section and a mixture of plastic sliding material that is applied to the expanded metal section and in the openings thereof in addition to optionally containing fillers that improve caloric conductibility and tribiological properties and the supporting layer is glued using an additional PFA-layer arranged therebetween.
