Abstract: A roller chain may include a series of roller links and pin links Each pin link may include composite pin link plates, each having a metallic plate component and a plastic plate component. The metallic plate component may be fixedly mounted on a pair of spaced metallic pin members, and the plastic plate component may be fixedly connected to the metallic plate component and have a pocket formed therein that complementarily receives the metallic plate component.

Abstract: The present disclosure relates to a handheld, single-piece wear gauge for chains, and more specifically, to a wear gauge with an elongated body carved into segments with markings, varied widths, and varied heights arranged along a guiding back rail. A roller chain wear gauge includes a single-piece body with a measuring end and a handle connected to the measuring end, wherein the measuring end includes a plurality of adjacent and contiguous calibrated segments each having a measuring length, a measuring width, and a measurement marking, and wherein the measuring end defines on one side a back rail formed by an alignment of a first side of each of the calibrated segments and a step function formed by the second side of each of the calibrated segments.
