SANY Excavator Track Chain, Shoes and Rollers

Track link assemblies, track shoes, bottom rollers and carrier rollers for SANY SY-series excavators. Undercarriage wears as one system, so we quote it as one: fitting new chain against a worn sprocket destroys both, and when chain pitch has reached its wear limit the sprocket belongs in the same shutdown. Two details decide the part number and neither is readable from the model name. First, roller count differs between the standard and long-undercarriage builds of the same machine — count the bottom rollers on one side and tell us the number. Second, shoe width is a separate specification from the machine model, since the same SY215C is built with several widths for different ground conditions, and the shoe bolt pattern follows the chain rather than the machine. Abrasive quarry rock and lateritic soils cut undercarriage life well below the manufacturer figures, which is worth planning stock around rather than discovering mid-season.
