Abstract

A device for coating metallic internal surfaces of cylindrical objects, particularly cylindrical sliding sleeves, by rubbing materials onto said surfaces includes one or a plurality of rubbing heads each including rubbing pins positioned in said rubbing head at an angle relative to each other. Each rubbing head is displaceable along an axis thereof. A rotationally-fixed housing carries a rotatable bevel gear. The rubbing head is rotational and provided with pinions meshed with said bevel gear.
