A method of forming a tensioner arm bracket, chain guide, snubber or tensioner arm with two shot injection molding. The tensioner arm bracket, chain guide, snubber or tensioner arm each having a body and a chain sliding face. The body of the tensioner arm bracket, chain guide, snubber or tensioner arm bracket is formed of by a first shot of thermoplastic polymer or thermosetting resin and the chain sliding face is formed by a second shot of thermoset elastomer which is overmoulded onto the body. The body of the component is made of either a thermoplastic or thermosetting resin is fixed to its chain sliding face either by one or more of an anchor point generated by undercuts in the body and/or chemical bonds between the dissimilar materials.

A cylindrical workpiece with a helical axial groove allowing for centerless grinding which has an angular overlap around the outer circumference on the body of the workpiece. The angular overlap ensures continuous tangential contact with the grinding wheels as the workpiece is rotated.

An auxiliary-cooled electronics assembly comprises a metal extrusion that includes: one or more cooling conduits extending axially along a length of the metal extrusion with a first open end in fluid communication with the cooling conduit(s); and a second open end in fluid communication with the cooling conduit(s); a first end cap coupled to the first open end forming a fluid-tight seal between the first end cap and the metal extrusion; a second end cap coupled to the second open end forming a fluid-tight seal between the second end cap and the metal extrusion; and one or more electrical circuit components, electrically linked together to form an electrical circuit, mounted to the metal extrusion.
