VANROCK — Technical Reference
Rubber Track Size Chart
Rubber tracks are identified by three numbers: width × pitch × number of links (e.g. 300x52.5x84). Width and pitch are cast into the inside of the track — the chart below lists every size VANROCK manufactures and the machines each size fits.
How to read a rubber track size
01
Width
The track's width in millimetres, measured across the outside face (e.g. 300 mm).
02
Pitch
The distance in millimetres between the centres of two adjacent metal cores (e.g. 52.5 mm). N/W after the pitch marks a narrow or wide guide-lug variant.
03
Links
The total number of metal cores. Machines of the same model can use different link counts — always confirm on your current track or with your serial number.
Can't read the marking? Measure the width with a tape, measure core-to-core distance for the pitch, and count the cores for links.
Letter prefixes mark OEM-specific track designs: B = Bobcat-style core (e.g. B320), Y = Yanmar-style core. These only fit the matching undercarriage design, even when the width looks identical.
