A track system for a track vehicle which has a crawler chain and a driving sprocket wheel. The chain has links each of which has a pin assembly with a bushing or one piece bolt the outer periphery of which at least is composed of a material consisting of Si.sub.3 N.sub.4 silicon nitride or a zirconium oxide with at most 15% of sintering additives. The driving sprocket wheel can have segments formed with the teeth and bolted to a disk, the segments being composed of a material consisting of Si.sub.3 N.sub.4 silicon nitride or zirconium oxide with less than 15% of sintering additives.
