EXCAVATOR STEEL TRACKS & PADS

Our steel chain links, made from a high-precision forging process, are heat treated to ensure durable core tenacity and hardness in the areas exposed to extreme wear. The heat-treatment reduces the chipping caused by violent knocks or strikes. All steel chain parts are high-precision machined. Additional hardness through heat treating is done on all critical wear areas.

1.Track Assembly: Complete track groups are built with top quality precision parts. All parts are hardened and tempered to prevent cracking under extreme conditions to keep your machine operational.

2.Track Chains: All of our track links are forged from top quality 35Cr and 40Cr carbon chromium steel. The track link body is manufactured to a hardness of HRC33~37 and the top surface of the track links are manufactured with an induction heating process to a hardness of HRC52~56.

3.Track Shoes: All of our track shoes are milled into a long profile from top quality manganese boron steel billet (23MnB). The profiles are then precision cut to the required length and both bolt-holes and mud-holes are punched out to accommodate for the required sizes.

• Increases external wear life by 20% or more. See the graph.

• Link life, normally limited by bushing wear, is better utilized because internal and external bushing wear life is extended.

• Overall system wear life is enhanced by 25% or more due to the combined improvements of internal wear, external wear, and sprocket wear.
