Strict Standard Compliance: Meets international standards (ISO 606:2015, ANSI B29.1, DIN 8187) and holds ISO 9001, CE, SGS certifications, ensuring compatibility with major machinery brands like John Deere and Kubota.
Application Adaptation & User Value Advantages
Wide Compatibility: Comprehensive product series (SP/SH/A/CA/S/C) cover power transmission, material conveying, and specialized needs for tractors, harvesters, seeders, and more. Precision & Reliability: Offers Grade 6 high-precision chains for seeders (uniform spacing) and Grade 7-8 cost-effective options, with strict pitch tolerance (≤±0.05mm) for stable operation. Low Maintenance & Longevity: Robust structure, wear-resistant components, and field-friendly maintenance (easy lubrication, replaceable parts) reduce downtime and extend service life.
Technical Specifications
Our agricultural chains’ technical specifications are engineered to meet the rigorous demands of agricultural machinery, adhering to global standards and precision manufacturing. Covering core parameters, compliance criteria, and structural-material technologies, they ensure reliability, durability, and compatibility across diverse farming scenarios—here’s the detailed breakdown:
Basic Core Parameters
Pitch (p): Center distance between adjacent pin axes, core load-bearing parameter. Range: ANSI #40 (12.7mm) - #120 (38.1mm), DIN 10B (15.875mm) - 32B (50.8mm); pitch tolerance ≤±0.05mm (ANSI #40-#80). Roller Diameter (d₁): Optimized for sprocket meshing and anti-clogging, d₁≈0.625p (ANSI) or 0.571p (DIN). Range: 8mm - 30mm (e.g., ANSI #60→19.05mm). Pin Diameter (d₂): Critical for shear strength, thicker than industrial chains (d₂≈0.4p). Range: 5mm - 20mm (e.g., ANSI #50→7.94mm). Breaking Load (F₈): Tested per ISO 606:2015/SAE J1940. Range: 20kN - 800kN (heavy-duty tractor chains→500-800kN). Operating Speed (v): 0.5-3m/s (power transmission); 0.1-1.5m/s (material conveying). Weight per Meter: 1kg/m - 30kg/m, balanced for strength and energy efficiency.
Precision Grades & Standard Compliance
Precision Grades (ISO 1328-1) Grade 6: High precision for seeders; pitch cumulative tolerance ≤±0.04mm/10 links, ensuring uniform seed spacing. Grade 7-8: Most common for tractors/harvesters; pitch cumulative tolerance ≤±0.06mm/10 links, balancing strength and cost. Grade 9: Low precision for auxiliary components, cost-effective for non-critical transmission. International Standards Compliance Core standards: ISO 606:2015, ANSI B29.1-2014, DIN 8187/8188:2017, JIS B1839:2010, GB/T 1243-1997. Certifications: ISO 9001, ISO/TS 16949, SGS 14001, CE, FDA 21 CFR Part 177 (grain-contact chains).
Structural & Material Technologies
Material Selection Link Plates: 20CrMnTi (carburizing+quenching, HRC58-62) for heavy-duty; 45# (quenching+tempering) for light-duty. Pins/Bushings: GCr15 (HRC60-64) for high impact; 20CrMnTi (carburizing, case depth 1.0-1.5mm) for general use. Rollers: 10# (carburizing+quenching) for standard; GCr15 for high wear. Special Environments: 304/316 stainless steel or galvanized steel (salt spray test ≥500 hours). Structural Design Optimization Multi-row structure (2-4 rows) for heavy-duty chains, load capacity 2-4x single-row. Anti-clogging design: Enlarged roller spacing, open link plates, smooth surfaces. Attachments: Flat/bent plates (≤80kg/attachment), buckets (≤150kg/bucket), extended pins (≤200kg/attachment). Core Manufacturing Processes Heat treatment: Alloy steel carburizing (850-950℃)→quenching→tempering; carbon steel quenching→tempering. Machining: Roller grinding (circularity ≤0.01mm), pin/bushing honing (Ra≤0.4μm). Surface treatment: Hot-dip galvanizing, electrophoretic coating, hard chrome plating.
