Abstract
The present invention pertains to a lubricant for a ball-and-socket joint, wherein spherical particles of two different sizes are introduced into an oil or a lubricating grease. The coarser particles act as spacers, which prevent the ball of the ball-and-socket joint from lying on a bearing shell during standstill of the ball-and-socket joint. The finer particles prevent the coarser particles from agglomerating and keep the coarser particles spaced apart from one another and they also keep them distributed in the ball-and-socket joint as a result.
