Abstract

The rotatably mountable track chain roller has two molded axle journal stubs which each engage rotatably in an end cap formed as a radial and axial bearing. Further expecially the track chain roller is provided with lubricant material for its bearings which has a lubricant action on them. An easy and economical manufacture for the track chain roller results when at least one spacer suitable for providing a set value of axial play in the axial direction of the track chain roller is clamped between the track chain roller and one of the end caps without play. The spacer is made of a soft grindable lubricant-resistant material which does not influence the lubricant action and which is grindable against the track chain roller, the axial journal and the end cap. The spacer can be ring shaped and have a plurality of approximately equal width spacing maintaining regions distributed approximately equally circumferentially around the ring and connected by straps of a narrower width. Advantageously the width of the straps is approximately a fifth of the width of the spacing maintaining regions.
