CA 2277256

An undercarriage for a construction machine having a support frame and at least one carrier roller positioned on an upper surface of the support frame for providing upper guidance to the chain or band. The carrier roller is constructed from two bearing pins coaxially arrange on opposite sides of the roller, and includes a plurality of axially parallel driving pins arrange equidistantly along a coaxial circumferential circle on one side face of the roller. The driving cams on the chain engage between two adjacent driving pins thereby eliminating relative movement between the chain or band and the carrier roller.
