Track Links are strictly quality-control and processed by advanced machine in order to maintain the stable structure. Furthermore, they are dealt with middle-frequency quench and normal mechanics dealing to reach qualified hardness and resistance-proof pressure. Thirdly, according to physics, structural mechanics and the accurate machine request, we make sure that each sprocket will operate smoothly and avoid the edge of sprocket slit. Finally, Sprockets will be checked in order to reduce the defect of operation. We have dealt in sprocket for many years and export to Singapore, Malaysia, Turkey, Brazil. We believe our quality will testify our words. 1-bulldozer: D20, D31, D50, D60, D80, D155, D3C, D4D, D5, D6D, D6D-LS, D7G, D6H, D7H, D8K 2-excavator: PC60-5, PC60-6, PC100-3, PC100-5, PC200-3, PC200-1, PC200-3, PC200-5, PC300-5, PC200-6, PC400-5, HD400, HD450, HD550, HD700-2, HD770, HD820, HD1250, UH0083, UH07-7,
