These components are formed from processed, heat-treated from rolled steel (specialty steel) and fastened to link belts with nuts and bolts. They must be tough and durable enough to survive continuous contact with the ground.
Links are one of the components that make up tracks. They form the main part of the track, connecting adjacent links to the pins and bush shoes.
Pins are joint components that serve to connect one link to another. Since pins bear the weight of the vehicle through the bush, strength is a key factor.
Bushes are cylindrical components into which the pins are inserted to ensure joints move smoothly. The inside slides along with the pin, while the outside slides with the sprocket. Thus, they must be highly resistant to wear.
