Our factory can produce a wide range of track link which pitch ranging is from 90mm to 226mm, they are suitable for all kinds crawler machinery of excavator, bulldozer, agricultural machinery and special machinery. Dry track chains, sealed and greased excavator track chains, lubricated chains for high performance applications. The track link has been done the medium-frequency hardening treatment,which ensures its highest strength and abrasion resistance. The pin is done the tempering and the surface medium-frequency quenching treatment,which ensures the sufficient hardness of core and abrasion resistance of external sunaces. The bush is done the carbonization and the surface medium-frequency quenching treatment,which ensures the reasonable hardness of core and abrasion resistance of internal and external surfaces.
