Our Tuffpart sprocket 402ID 22+8H 21T is precisely crafted from steel alloys, utilizing either casting or forging methods. Afterward, they undergo a precise heat treatment process and machining to meet exacting standards. The composition of the steel alloy is of paramount importance, as an insufficient amount of carbon can render the steel brittle during the hardening process. Moreover, merely surface hardening the sprocket leads to rapid wear. To ensure the correct depth of hardening, our sprocket teeth undergo induction hardening, guaranteeing durability and performance. TKV has far and away Australia's biggest range of tracks and undercarriage components. Our warehouses, in places like Melbourne, Sydney, Brisbane, Adelaide and Toowoomba, carry loads of excavator rubber track pads. So, when you're in a hurry, we usually have what you need in your state. And it is ready to go!
