  • the component or wheel that transmits motion from the engine to the chain is known, depending on the embodiments, as sprocket, segment or tumbler.
  • undercarriage components are subject to high wear.
  • the wear of the components arises from the mutual friction of the surfaces of mutually coupled components which can move with respect to each other and of these components with respect to the ground.
