Slide bushings made of metal powder materials are used in many parts of vehicles. The current trend is to reduce the unit cost of products, increase the durability of components and assemblies, and reduce the harmful effects on the environment. One of these solutions is the use of powder materials. In this article, we consider some manufacturing techniques for sliding bushings of a lever brake system of a rolling stock using one-sided and two-sided pressing, pulse and combined sealing. The areas of their rational use are demonstrated as well.
