2. Abrasion-Resistant Protection
Standard zinc plating fails within 200 hours in abrasive soils. Our Geomet® 3210 coating combines zinc-aluminum flakes with ceramic nanoparticles in a chromate-free matrix. Independent testing (ASTM D968) demonstrates 2,500+ hours salt spray resistance and 30% higher abrasion resistance than Dacromet. The 15-20μm coating withstands rock gouging during track articulation while maintaining 0.35μ surface roughness for consistent friction coefficients. Color-coded violet finish enables visual wear inspection without gauges.
1. Extreme Load Engineering
Track shoe bolts endure 5X higher shear loads than standard chassis bolts due to direct ground impact. Our M24x120mm bolts utilize quenched & tempered 42CrMoV4 steel (DIN EN 10269) achieving 1220MPa tensile strength. Proprietary cold-forging creates continuous grain flow in shank transitions, increasing fatigue resistance by 40% versus hot-forged alternatives. Finite element analysis confirms uniform stress distribution under 380kN cyclic loading - critical for 50+ ton excavators operating in rock excavation. Bolt head geometry incorporates 12-point flange design to prevent rotation during track flexing.
