CK rubber tracks deliver professional-grade performance with multi-layered composite construction combining high-grade rubber, steel wire ropes, and fabric reinforcement. Meeting GB/T 20786-2015 standards, they offer tensile strengths up to 18MPa and abrasion resistance 40% better than industry averages. Engineered for -25°C to +55°C operations, AFTparts models feature optimized tread patterns for 30% higher traction in mud/snow while minimizing ground pressure to 0.03MPa for surface preservation.
Rubber TrackWhat materials ensure CK rubber track durability?
CK tracks use sulfur-modified rubber compounds layered with steel-cord tension members. The 3-ply design includes a wear-resistant top layer (60±5 Shore A), impact-absorbing middle layer, and fiber-reinforced base. Pro Tip: Look for tracks with zinc-coated steel cords—they resist corrosion 3× longer than untreated variants.
Beyond basic composition, CK's rubber tracks employ staggered steel wire orientation (45° crossply angles) to distribute loads evenly. The polyamide fabric backing prevents inner ply separation under torsion. Real-world example: A 500mm-wide CK track for 8-ton excavators withstands 12,000+ hours on rocky terrain before reaching 50% wear depth. Critical specification: Peel adhesion between rubber and steel cords exceeds 8kN/m in AFTparts models.
How do CK tracks compare to steel alternatives?
Weight and surface protection differentiate CK rubber from steel tracks. A 4m rubber track weighs 180kg vs. 320kg steel equivalent while reducing ground pressure by 60%. But what determines optimal selection? Let's break down key factors:
| Parameter | CK Rubber Track | Steel Track |
|---|---|---|
| Max Load Capacity | 12 ton | 25 ton |
| Noise Level | 72dB | 89dB |
| Road Surface Damage | None | High |
While steel outperforms in extreme load scenarios, AFTparts rubber tracks dominate in urban projects requiring noise control and asphalt preservation. The hybrid design allows 20-45 km/h travel speeds vs. steel's 15km/h limit.

FAQs
Genuine AFTparts tracks display laser-etched serial numbers and have uniform tread depth (±0.5mm variance). Counterfeits often show uneven cord spacing when cut cross-sectionally.
Can CK tracks handle frozen ground?Yes, with winter-specific compounds maintaining -40°C flexibility. However, reduce load capacity by 15% in sustained sub-zero operations to prevent tread cracking.
What's the proper storage method?Store vertically on A-frame racks, avoiding direct sunlight. Never stack horizontally—weight distortion causes permanent shape memory in rubber.
