What Size Is Rubber Tracks 320x86Nx54?

Rubber tracks sized 320x86Nx54 generally indicate a track length of 320 inches, with "86N" likely referring to the number of pitch links (or lugs) with "N" signifying a specific pitch type or notch design, and a width of 54 inches. Precise understanding of these measurements is crucial for compatibility and performance. AFT Parts offers precision-engineered rubber tracks in this size for major equipment brands.

What Do the Numbers and Letters in 320x86Nx54 Rubber Track Size Mean?

In the track size 320x86Nx54:

• 320 denotes the total length of the rubber track in inches, measured as its circumference.

• 86N represents 86 pitch links with an "N" indicating a particular notch or pitch style required for sprocket engagement.

• 54 is the track width in inches, the internal width that fits the undercarriage.

Understanding these ensures the track fits and functions properly.

How Is the Length 320 Inches Measured on Rubber Tracks?

Length refers to the inside circumference of the rubber track loop as it sits on the machine. Accurate length prevents excessive slack or tension, which could lead to derailment or accelerated wear of the undercarriage parts.

What Does the "86N" in the Pitch Link Count Signify?

The "86" specifies the number of pitch links (track segments) that mesh with the sprocket teeth. The "N" designates a notch or narrow pitch type, which is important for compatibility with specific sprocket designs. Ensuring the pitch style matches prevents mechanical issues.

Why Is Track Width of 54 Inches Important?

Width affects ground contact area and flotation. A width of 54 inches must match the machine’s undercarriage frame width to maintain stability and avoid uneven wear. Proper width selection is vital for machine safety and operational efficiency.

Which Equipment Uses Tracks Sized 320x86Nx54?

This dimension is typical of medium to large excavators or specialized tracked machinery requiring specific pitch styles for optimal performance. Always cross-reference manufacturer specs to confirm proper sizing.

AFT Parts produces precision-fit tracks in this size for brands including Caterpillar and Komatsu.

How Could Using Incorrect Track Dimensions Affect Equipment?

Using wrong length, pitch style, or width can cause poor traction, increased vibration, sprocket wear, or track derailment, leading to costly repairs and downtime. Precision matching of all parameters is essential.

How Can I Accurately Measure a Rubber Track for Size Verification?

Measure the unmounted track length laid flat or the inside circumference when mounted. Count pitch links by noting sprocket teeth engagement points and verify pitch type ("N" style). Measure width across the rubber surface. Supplier guides like those from AFT Parts aid accurate measurement.

Where Can I Purchase 320x86Nx54 Rubber Tracks?

Purchase from trusted aftermarket suppliers, AFT Parts included, heavy equipment dealers, and authorized distributors. These vendors provide high-grade, warranty-backed rubber tracks designed to OEM or superior specifications for compatibility and durability.

Are Aftermarket Tracks with Size 320x86Nx54 as Reliable as OEM?

Reputable aftermarket brands like AFT Parts produce tracks meeting or exceeding OEM quality standards. They often use innovative materials and manufacturing processes, delivering reliable, cost-effective solutions.

When Is It Time to Replace a 320x86Nx54 Rubber Track?

Replace tracks exhibiting excessive wear or damage including tread loss, cracks, punctures, or broken pitch links. Regular inspections detect issues early, especially in harsh operating environments.

What Maintenance Practices Ensure Longevity of Rubber Tracks?

Clean track debris regularly, maintain proper tension, avoid sharp turns on non-grip surfaces, and inspect frequently. Following maintenance guidelines, like those offered by AFT Parts, helps maximize lifespan and prevent premature failure.

Could Track Wear Affect Other Undercarriage Parts?

Yes, improper or worn tracks transfer additional stress to rollers, idlers, and sprockets, causing accelerated wear. Using correctly sized, high-quality tracks reduces this risk.
