A drive chain has a plurality of pairs of link elements with the elements each pair extending longitudinally parallel to each other and having relatively widely spaced outer ends formed with transversely open and confronting blind bores and relatively closely spaced inner ends formed with axially throughgoing and transversely aligned bores. Each pair of inner ends lies between a respective pair of outer ends with the bores coaxial and receiving respective pins defining respective transverse axes, each fitting tightly in the bores of the inner ends, and having ends rotatably seated in the respective bores of the respective outer ends. Respective sleeves surround the pins between the respective inner ends. Respective outer seal rings between the outer ends and the pin ends define with the pin ends outer compartments and respective inner seal rings between the inner ends and the sleeve define between the respective pin, sleeve, and inner ends an inner compartment. Respective bodies of lubricant at least partially fill the compartments.

In order to create a track roller for crawler chains, consisting of a track oller body, an axle traversing the same as well as bearings and seals arranged between the track roller body and the axle, whereby the axle is affixed to a mount with its ends axially protruding from the track roller body, which has a long life when used as intended, the invention proposes that the bearings (3) radially arranged between the track roller body (1) and the axle (2) be designed as pivoting bearings, so that the load-caused bending of the track roller body or the axle can follow without jamming.
