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.
