What is a track chain link and why does its wear matter?

Expert Answer

A link is an individual component that makes up the track chain on an excavator or bulldozer. Links are connected with pins and bushings to form the complete chain that transmits traction and supports the machine load. When a link wears, the pin, bushing, and the contact area with the sprocket usually wear as well, which can cause looseness, noise, poor alignment, and increased undercarriage wear. That is why it is important to inspect wear before it affects the entire chain. VANROCK manufactures track chains and other undercarriage parts for many machinery brands; if you need a replacement, pricing is available on request through our authorized distributor network. If your machine is Caterpillar, Komatsu, or another OEM brand, VANROCK is an independent manufacturer and is not affiliated with the OEM.
