Within Under Carriage, Track Chain covers the steel track chains fitted to plant tracked-equipment undercarriages — the assembled chain of track shoes, pin links, bushings, and connecting hardware that wraps around the sprocket and idler to provide the running surface and traction. Track chains include both bare track-chains (for use with separate track shoes) and complete track-chain assemblies (with shoes installed).
Parts for Machines supplies track chains across the plant aftermarket — covering chains for the major plant equipment ranges, sized to match specific equipment final-drive sprocket and idler geometries.
Product pages list the equipment make and model the chain is approved for, the chain type (bare chain or shoe-assembled), the chain pitch (the distance between adjacent pin centres — must match the equipment's sprocket tooth pitch and idler diameter), the pin-and-bushing specification (diameter, length, hardness rating), the link count (the number of pin links in the complete chain — must match the equipment's track-frame length and tension-adjustment range), the construction (sealed-and-lubricated for modern equipment; standard for older equipment), the rated load capacity, and the OEM cross-reference.
For replacement of an existing track chain, the OEM part number is the most reliable match. Where the OEM number isn't available, identify by the equipment make, model, year, and the chain's measured pitch and link count. Always replace track-chains as part of a matched undercarriage rebuild — sprockets, chains, idlers, and rollers worn together must be replaced together. Track-chain elongation should be measured periodically across the chain length — when elongation exhausts the idler tension-adjustment range and the track cannot be properly tensioned, the chain has reached its replacement point.
