Rubber Track Size Guide: Understanding Width x Pitch x Links

Understanding Rubber Track Sizing

Every rubber track has a specific size designation that tells you exactly what machine it fits. Understanding this sizing system is essential for ordering the correct replacement tracks.

The Size Format: Width x Pitch x Links

A rubber track size like 400x86x52 breaks down as:

400 = Track width in millimeters

86 = Pitch (distance between links) in millimeters

52 = Total number of links

Width Explained

The width determines:

Ground pressure distribution

Stability

Compatibility with your machine's undercarriage

Common width ranges:

Mini excavators: 230mm - 400mm

Compact track loaders: 320mm - 450mm

Large CTLs: 400mm - 500mm

Pitch Explained

Pitch affects:

Track compatibility with your sprockets

Overall track length

How the track engages with the drive system

Common pitch sizes:

52.5mm - Small mini excavators

72.5mm - Medium machines

86mm - Compact track loaders

101.6mm (4") - Large excavators

Links Explained

The link count determines:

Total track length

Tension adjustment range

Machine-specific fit

Why it matters: Even if width and pitch match, wrong link count = wrong track.
