How do I find the right rubber track size for my machine?

Question

VANROCK Track Solutions · Accepted Answer

The right rubber track size is usually shown on the old track as width x pitch x links, such as 300x52.5x84. If that marking is missing or unreadable, measure the track width, the center-to-center distance between two adjacent drive lugs, and the total number of links around the loop.

Use the machine itself as the final check, not just the model name. The same machine model can leave the factory with different track sizes, depending on undercarriage setup, region, or options. If you have the machine serial number, that helps narrow it down fast when you request a quote through VANROCK’s appointed dealer network.

A few details matter beyond the three numbers:
• Width: the first number in millimetres, measured across the track
• Pitch: the spacing between lug centers, which must match the sprocket
• Links: the total count, which determines overall fit
• Guide type and core style: these must suit the machine’s undercarriage, especially where the rollers or sprocket use a specific guide profile

Common mistakes are relying on the brand or model alone, measuring only the outside of the track, or ignoring visible wear on the lugs and sprocket. If the pitch is wrong, the track may fit poorly, jump teeth, or wear the undercarriage faster. If you are replacing an old track, compare both sides of the machine and check for any OEM-style code printed on the inside. If an OEM brand is named, note that VANROCK is an independent manufacturer and is not affiliated with that OEM.

For the quickest match, send VANROCK your current track code, machine make and model, and serial number. VANROCK supplies rubber tracks for mini excavators, midi excavators, and compact track loaders across 350+ machinery brands, with pricing available on request through the dealer network.
