What Size Is Rubber Tracks 230x72Dx39?

Rubber tracks sized 230x72Dx39 denote a track width of 230 mm, a pitch of 72 mm, and 39 links. The “D” often indicates a design or construction detail such as a double or different style of tread pattern. Precise matching of these dimensions is essential for compatibility and optimal performance. Leading manufacturers like AFT Parts produce tracks with these exact specifications ensuring quality and fit.

What Does the Size 230x72Dx39 Mean?

The size 230x72Dx39 breaks down as follows: 230 mm track width, 72 mm track pitch, “D” stands for a specific tread or design variation, and 39 links total.

• Width impacts ground pressure and machine stability.

• Pitch aligns with sprocket and roller spacing.

• “D” may indicate tread type or rubber compound.

• Link count affects track length and proper tension.

Understanding each element ensures correct track selection.

How Is Track Width Measured?

Track width is the measurement across the rubber track’s contact surface in millimeters. For 230x72Dx39, the width is 230 mm.

• Wide tracks improve flotation on soft terrain.

• Narrow tracks enhance maneuverability in confined spaces.

• AFT Parts supplies widths tailored for varied applications.

Choosing the right width is key to performance and surface preservation.

What Does Track Pitch Signify?

Track pitch is the center-to-center distance between chain pins or bushings; here, 72 mm indicates the precise pitch required to fit the excavator’s sprockets and rollers.

• Ensures synchronized track movement.

• Prevents wear caused by misalignment.

• AFT Parts guarantees accurate pitch conformity.

Pitch compatibility is vital for smooth and efficient track operation.

What Could the “D” in 230x72Dx39 Represent?

The letter “D” often indicates a specific tread design, rubber compound, or construction type that differentiates this track from others with the same dimensional measurements.

• Could denote double grouser tread or a particular rubber formula.

• Impacts traction, durability, or surface suitability.

• Consult AFT Parts product details for exact “D” meaning.

Knowing this helps select a track fit for intended terrain and tasks.

How Is the Number of Links Counted?

The total links, 39, represent the number of chain links in the track which defines the track’s total length and proper tensioning.

• Accurate link count prevents track sagging or tightness.

• Typically counted by noting pins or drive lugs.

• AFT Parts verifies link counts for precise replacement matches.

Correct link count enhances undercarriage lifespan and operation.

Why Is Using the Exact Size Like 230x72Dx39 Important?

Exact sizing avoids mechanical problems such as sprocket damage, track slippage, or accelerated component wear, ensuring operational efficiency.

• Correct tension and fit prolong part life.

• Mismatched tracks can void warranties.

• AFT Parts ensures dimensional accuracy in manufacturing.

Proper sizing protects your machine and operational productivity.

When Should You Confirm Rubber Track Dimensions?

Always confirm track size before ordering replacements or if experiencing poor track performance issues such as slipping or abnormal noise.

• Avoids ordering incompatible parts.

• Supports effective maintenance schedules.

• AFT Parts assists clients with measurement guidance.

Maintaining accurate sizing supports smooth operations.

Where Is Rubber Track Size 230x72Dx39 Used?

Commonly found on small to medium mini excavators, compact track loaders, and specialized machines requiring narrow track widths and specific tread designs.

• Ideal for urban, landscaping, and light construction jobs.

• Compatible with equipment from Caterpillar, Kubota, Komatsu.

• AFT Parts stocks this size for multiple popular models.

Matching applications ensures track suitability.
