As a professional agricultural machinery supplier, Shandong Lifetree Machinery Co., Ltd. provides high-strength, sealed disc harrow bearing assemblies for global clients. Contact via WhatsApp for customization: +86 178 6293 9397.
Our bearing systems are engineered for harsh operating conditions:
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 .
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 .
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 .
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.
