Definition of TE Pitch
The term "TE Pitch" refers to the distance between the drive lugs or teeth on a tracked heavy equipment machine’s undercarriage. It is measured from the center of one lug to the center of the next, typically in millimeters. This dimension is crucial for selecting compatible rubber tracks or metal track links.
Short Pitch vs. Long Pitch Tracks
Accurate measurement involves:
Choosing the correct pitch is essential because the sprocket and track must match precisely to prevent skipping, increased wear, or track slippage. Tracks with the wrong pitch can lead to premature undercarriage failure and decreased operational efficiency.
Terminology Explained
TE pitch is a fundamental specification that influences track selection, machine performance, and maintenance intervals. Understanding the difference between short and long pitch tracks guides operators and service professionals in selecting the right undercarriage components to extend equipment life and maximize operational efficiency.

Short Pitch vs. Long Pitch Tracks
- Short Pitch Tracks have a smaller distance between drive lugs. This means the track engages every sprocket tooth, resulting in smoother operation, reduced vibration, and less wear on the undercarriage components. Short pitch rubber tracks enhance ride comfort and improve machine longevity.
- Long Pitch Tracks have drive lugs spaced further apart, engaging every other sprocket tooth. While this design is less smooth and increases vibration and wear, it can perform better in sandy or soft soil conditions by reducing soil packing.
Accurate measurement involves:
- Measuring from the center of one lug tooth to the center of the adjacent lug tooth, not just the gap.
- Counting the number of links (teeth) around the track circumference to verify track size and fit.
- Considering the guide system (Inside Guide or Outside Guide) which affects how the track interfaces with bottom rollers and idlers, including measuring inner or outer bottom widths accordingly.

Terminology Explained
- Drive Lug: The raised tooth or protrusion on a rubber or metal track that engages the sprocket.
- Sprocket: A toothed wheel that meshes with the track drive lugs, transferring power to move the machine.
- Guide System: The track system mechanism that keeps the track aligned via rollers or idlers either inside or outside the track links.
- Undercarriage: The tracked part of heavy equipment including tracks, rollers, idlers, and sprockets.
- Always verify pitch and track dimensions before ordering replacements to ensure compatibility and optimal performance.
- Short pitch tracks are generally preferred for most applications due to their smoother operation and longer life cycle.
- Consider ground and soil conditions when choosing between long and short pitch; long pitch may offer advantages in specific challenging terrains.
- Work closely with manufacturers or specialists for precise measurements and recommendations.
