Keep your harvest on schedule with parts built for mud, dust, vibration, and long working days. JOC supplies OEM-grade components for tractors, combines, seeders, and irrigation systems, uniting robust metallurgy with farm-tested design. As a China manufacturer and global supplier, we balance durability with serviceability, ensuring your equipment stays productive across seasons.

Start with duty cycle and environment: abrasive soil, fertilizer corrosion, impact, and shock loads. We recommend heat-treated alloy steels for high-load gears and shafts; ductile iron or forged steel for hubs and yokes; and anti-corrosion coatings for linkages and fittings. Our TS16949 approach controls raw material certificates, hardness profiles, grain flow in forgings, and dimensional stability after machining—so parts fit the first time and keep fitting.
Because uptime matters more than promises. We design for easy maintenance, interchangeable spares, and stable supply in peak seasons. With tiered QA—from PPAP documentation to 100% critical-dimension checks—we deliver parts that pass inspection and pass the field test. Need prototypes before planting? Let’s move fast.
