The data on the effect of electromechanical mandreling (EM) modes of rolled bushings made of Bronze-Tin-Zinc-Lead (BTZL) 4-4-2.5 on the lead yield from the matrix material to the work surface are given. As a result of an X-ray analysis, it was found that up to 13.3% of lead is eliminated from the matrix material to the bushing’s surface, filling all irregularities after machining, bringing the actual contact area to the contour one and significantly reducing contact stresses under loading, which serves as a reserve for increasing the movable joint’s durability, along with decreasing the friction torque in the joint when operating under ‘film’ starvation conditions.
