⚡ Structural Advantages & Heavy-Duty Performance

168mm Oversized Flange Architecture: Heavy-duty integrated 168mm flange housing with 82mm depth provides maximum axial rigidity, superior torque absorption, and zero alignment deflection under deep soil penetration.

Double-Row Angular Contact Internal Core: High-precision double-row ball geometry engineered to handle extreme simultaneous radial and axial dynamic shock loads during continuous high-speed field drag.

Heavy-Duty Multi-Lip Cassette Sealing: Advanced multi-lip cassette rubber seals form a bulletproof shield against moisture, mud, slurry, and abrasive soil grit contamination.

Maintenance-Free Synthetic Pre-Lubrication: Factory pre-filled with high-grade wide-temperature agricultural synthetic grease, completely eliminating daily routine field maintenance and lube washout.

🚜 Agricultural Machinery Deployment & Usage Scenarios

High-Speed Disc Harrows & Cultivators: Essential heavy-duty hub bearing assembly for large-diameter soil preparation discs, rolling coulter units, and stubble cultivators operating under intense field drag.

High-Speed Seeders & Disc Openers: Direct fit replacement flanged hub unit for heavy agricultural seed drills, seed openers, and high-speed tillage tools requiring a 34.9x168x82mm bearing.

Severe Duty Tillage Tools: Designed for deep tilling implements and high-hectare farm operations working under high field speeds and harsh, abrasive soil conditions.
