What do dozer undercarriage components include?

Expert Answer

Dozer undercarriage components are the wear parts that support the machine and move it across the ground. A typical dozer undercarriage includes track chains, track shoes, track rollers, carrier rollers, front idlers, sprockets or segment groups, track tensioning parts, and related bolts, nuts, pins, bushings and seals. On many machines, rubber pads may also be fitted for road work or finished surfaces. These parts work together to carry load, guide the track, and transfer drive power, so wear in one component often affects the others. VANROCK Track Solutions manufactures undercarriage parts for dozers and other tracked machines across 350+ brands. We sell exclusively through our appointed dealer network and quote pricing on request. If you are comparing parts for Caterpillar, Komatsu or another OEM brand, note that VANROCK is an independent manufacturer and is not affiliated with the OEM.
