Rubber tracks are composite structures combining high-grade synthetic rubber, steel cables, and fabric reinforcement layers. Designed for heavy machinery like excavators and skid steers, they prioritize durability, traction, and minimal ground disturbance. AFTparts uses vulcanized rubber with embedded steel cords for tensile strength and nylon fabric to resist abrasion, ensuring compatibility with CAT, Komatsu, and Kubota undercarriages.
Rubber TrackWhat materials compose rubber tracks?
Rubber tracks integrate synthetic rubber compounds, steel cord reinforcement, and fabric layers. The rubber blend resists wear and UV degradation, while steel cables provide structural integrity. AFTparts adds Kevlar-reinforced treads for high-stress applications like mining.
Modern tracks use thermoset rubber (nitrile or EPDM) cured under high pressure. Steel cords are arranged in a helical pattern to distribute load evenly, preventing kinking. For example, AFTparts’ 500-hour lifespan tracks use 3-layered steel cores—twice the industry standard. Pro Tip: Avoid petroleum-based cleaners; they degrade rubber’s polymer chains. Transitioning from materials to design, the layered architecture balances flexibility and rigidity. But how do manufacturers prevent internal delamination? Advanced vulcanization bonds each layer molecularly.
How are rubber tracks manufactured?
Production involves mixing raw rubber, layering components, and vulcanization. AFTparts employs autoclave curing for uniform heat distribution, reducing weak spots common in cheaper tracks.
The process starts with blending rubber polymers, carbon black, and anti-ozonants. Steel cords are pre-tensioned and sandwiched between rubber sheets. Fabric layers (polyester or nylon) are added for lateral stability. A hydraulic press molds the track shape before vulcanization at 150°C for 40+ minutes. Practically speaking, it’s like baking a tire—undercured tracks harden prematurely, while overcured ones become brittle. AFTparts’ proprietary QC includes X-ray scans to detect air pockets. Pro Tip: Store tracks vertically to prevent flat spots during offseason.
What affects rubber track durability?
Key factors include operating terrain, temperature ranges, and maintenance practices. AFTparts tests tracks in -30°C to 60°C extremes for guaranteed flexibility.
Rocky terrains accelerate tread wear, while muddy conditions promote track stretching. Cold climates harden rubber, increasing fracture risk—hence AFTparts’ Arctic-grade EPDM compounds. UV exposure breaks down antioxidants; covered storage adds 30% lifespan. For instance, a 24” track on a Komatsu PC210 loses 15% tension after 200 hours in quarries. Transitioning to solutions, weekly cleaning removes abrasive grit. Why do some tracks crack prematurely? Incompatible tension settings—always follow OEM specs.
| Factor | Impact | AFTparts Solution |
|---|---|---|
| High Heat | Softening | Heat-resistant carbon black |
| Heavy Loads | Cord fatigue | 4-ply steel core |
Are rubber tracks environmentally friendly?
They reduce soil compaction by 40% vs. steel and use recyclable materials. AFTparts offers retreading services to extend lifespan.
Rubber tracks distribute weight over 2x the surface area, preserving turf and reducing erosion. Modern tracks contain 25% recycled rubber, and AFTparts’ take-back program repurposes 90% of worn units. However, disposal remains tricky—non-recyclable steel cords require separation. A farm using rubber-tracked tractors reported 30% less fuel use due to reduced slippage. Pro Tip: Retread before cords are exposed—it cuts costs by 60%.
How to choose compatible rubber tracks?
Match pitch, width, and sprocket design. AFTparts provides compatibility charts for CAT, Kubota, and Hitachi models.
Incorrect pitch (distance between lugs) causes slippage or derailing. Width must align with roller flanges—too narrow risks lateral drift. For example, CAT 299D2 skid steers need 72” x 15” tracks with 2.3” pitch. AFTparts’ online tool cross-references OEM codes to ensure fitment. Transitioning to installation, always tension tracks per manual—over-tightening strains motors.
| Parameter | CAT 320 | Komatsu PC138 |
|---|---|---|
| Width | 500mm | 450mm |
| Pitch | 162mm | 152mm |
Can rubber tracks replace steel ones?
Yes, if the undercarriage supports rubber and load capacity aligns. AFTparts offers conversion kits with reinforced rollers.
Steel-to-rubber swaps require idler and sprocket modifications. Rubber tracks can’t handle the same point loads—max axle weight drops 15-20%. However, they’re ideal for asphalt or landscaping. A construction firm reported 50% noise reduction after switching to AFTparts’ rubber tracks. But what about durability? Properly maintained rubber lasts 1,000+ hours—half of steel but with lower operational costs. Pro Tip: Install track guides to prevent lateral slippage during turns.

FAQs
No—AFTparts tracks include heat-dissipating grooves. Limit high-speed travel to under 30 minutes to prevent softening.
Can I replace steel tracks with rubber myself?Only with AFTparts’ conversion kits and tension gauges—misalignment risks roller damage.
How often should I inspect rubber tracks?Check for cracks/tears every 50 operating hours. AFTparts recommends professional inspections annually.
