I. Core Components of Disc Harrow Bearing Assembly

Our bearing systems are engineered for harsh operating conditions:

  1. Spherical-Surface Ball Bearings & Custom Non-Standard Units

    • Self-aligning design withstands tilting torque and soil impact . Square/hexagonal inner holes nest directly with square shafts to prevent wear.

    • Customizable agricultural bearings (e.g., Model 5203KYY2) with heat-treated materials enhance torsional strength .

  2. Fully Sealed Bearing Housings

    • Precision-cast steel structures (net weight: 22kg) integrate double-bearing pressure assemblies with external grease fittings .

    • Oil-bath design with floating oil seals and triple-sealed structure (skeleton oil seal + labyrinth) prevents silt ingress for paddy/dry land use .

  3. Spool Systems & Sealing Protection

    • Split inner/outer sleeve structures connect discs via retaining rings; lengths (e.g., 230mm) match disc spacing .

    • Triple sealing: skeleton oil seals for shaft adhesion, labyrinth seals for grit interception, floating seals for clay soils .


II. Customization Advantages & Technical Guarantees

ISO-certified flexible production capabilities:

  • Global Supply: Products exported to 66+ countries (EU, Africa, Southeast Asia), supporting OEM/ODM for light/medium/heavy harrows .

  • Key Custom Projects:

    • Hardened Square Shafts: 41×41mm cross-section with 30% higher torsion resistance; RD-41 harrow series accessories .

    • Sealing Optimization: Custom oil seals for soil types (e.g., viscous clay/arid regions), doubling bearing lifespan.

  • Annual Capacity: 20,000 sets of machinery + 300,000 discs; ISO 9001 certified for export compliance.
