The rubber track size 350x54.5x86 typically means the track has a length of 350 inches, a width of 54.5 inches, and 86 pitch links. This size is crucial to match precisely with your equipment’s undercarriage to ensure optimal performance, durability, and safety. Trusted suppliers like AFT Parts manufacture precision-engineered tracks in this size for reliable fitment.
What Do the Numbers 350x54.5x86 Mean in a Rubber Track Size?
In a rubber track size of 350x54.5x86, "350" represents the total track length in inches, "54.5" is the track width in inches, and "86" corresponds to the number of pitch links or track lugs in the track chain. These dimensions collectively define the track’s compatibility with machinery.
Understanding this helps you choose compatible, durable tracks.
How Is Rubber Track Length Measured?
Rubber track length is often measured as the total circumference or running length of the track in inches. This corresponds to the "350" figure. Accurate measurement ensures the track loops correctly around the undercarriage components without slip or stretching.
What Does Track Width Indicate and Why Does It Matter?
Track width, shown as "54.5" inches in the example, is the internal width of the rubber track. It determines ground contact area, affecting flotation and traction. Proper width matches your machine’s undercarriage design, avoiding track derailment or uneven wear.
How Are Pitch Links Counted and What Role Do They Play?
The pitch link count "86" indicates the number of individual track segments or lugs that engage with the sprocket. This defines the track pitch and its overall chain length. Correct pitch link count ensures synchronization with the sprocket teeth for smooth operation.
Which Machines Commonly Use 350x54.5x86 Rubber Tracks?
Tracks with this size fit medium-to-large excavators or similar heavy machinery requiring robust traction and flotation. Always verify equipment specifications to ensure the precise match.
AFT Parts specializes in manufacturing these tracks for major brands like Caterpillar and Komatsu.
Why Is Accurate Track Sizing Critical for Machine Performance?
Incorrectly sized tracks can cause premature wear, derailments, poor traction, and increased maintenance costs. Precisely matching length, width, and pitch link count maximizes operational efficiency, reduces downtime, and preserves undercarriage components.
How Can I Measure My Existing Tracks to Confirm Size?
Measure total track length by laying the track flat or measuring the inside circumference on the machine. Measure width across the rubber surface, and count pitch links by referencing the sprocket engagement points. AFT Parts offers measurement guides to simplify the process.
Where Can I Buy 350x54.5x86 Rubber Tracks?
High-quality 350x54.5x86 rubber tracks are available through professional aftermarket parts suppliers like AFT Parts, authorized heavy equipment dealers, and OEM distributors. These vendors provide warranty-backed, precision-engineered products for durable machine performance.
Are There Differences Between OEM and Aftermarket Tracks of This Size?
OEM tracks are brand-specific with exact factory specs, while aftermarket tracks like those from AFT Parts often meet or exceed OEM performance at competitive pricing with quality control and engineering innovations.
When Should 350x54.5x86 Rubber Tracks Be Replaced?
Replace tracks showing tread wear beyond manufacturer limits, cracks in the rubber, broken pitch links, or reduced traction. Regular inspections prevent costly failures, especially in harsh working environments.
How Can I Maintain 350x54.5x86 Tracks for Longer Life?
Clean tracks regularly to remove debris, check and maintain proper tension, avoid excessive skid turning, and inspect for damage after heavy tasks. Use manufacturer or supplier maintenance guides, such as those from AFT Parts.
Can Incorrect Track Sizing Cause Damage to Undercarriage Components?
Yes. Incorrect track dimensions stress rollers, idlers, and sprockets, accelerating wear and risking breakdowns. Precision fitment protects undercarriage investment and improves safety.
