Rubber Track Size Guide: Width x Pitch x Links Explained (Chart)

Quick answer: A rubber track size is written as width × pitch × links (for example 300×52.5×80). Width is the tread width in millimetres, pitch is the centre distance between link pins, and links is the number of drive lugs/links around the belt. Measure the old track—or the undercarriage plate—before ordering. This page is the sizing hub; use it to reach size-specific articles and the catalog.

Rubber Track Sizing Guide: The Three Numbers

Number	Meaning	How to verify
Width	Overall tread width (mm)	Measure across the tread, or read the moulded code
Pitch	Distance between adjacent link pin centres (mm)	Measure several pitches and average; must match sprocket
Links	Count of drive links / lugs around the belt	Count full circle; do not estimate from length alone

Related code formats and letter suffixes (N, W, B, ZZ, etc.) are explained in rubber track size codes guide.

How to Measure Rubber Track Pitch

1. Relieve tension slightly so the belt sits flat on a section of links.
2. Measure centre-to-centre across several consecutive pins; divide for average pitch.
3. Compare to the moulded size code. If they disagree, trust careful measurement and confirm with Check Fitment—worn belts can read long.

Pitch must match the sprocket. Mixing pitches is a fast way to skip teeth and tear lugs. See also sprocket pitch explained.

Width, Pitch, Links and Performance

• Wider tracks lower ground pressure but need clearance in the frame.
• Wrong pitch destroys sprockets and tracks—never “close enough.”
• Wrong link count changes fit around idler and sprocket even if width looks right.
