⚡ Structural Advantages & Heavy-Duty Performance

• 185mm Massive Flange Architecture: Heavy-duty integrated 185mm flange housing with 113mm extended depth provides maximum axial stiffness, superior torque distribution, and zero alignment deflection under maximum tilling depth.

• Left-Handed Operational Design (LH): Engineered specifically for left-hand disc gang orientations to withstand counter-rotational dynamic forces and prevent hardware loosening during continuous heavy drag.

• Double-Row Angular Contact Internal Core: Engineered with high-precision internal double-row ball geometry to deliver exceptional dynamic radial and bi-directional axial load capacity under severe soil impact.

• Advanced Multi-Lip Cassette Sealing Barrier: Multi-lip cassette rubber seals form a permanent defensive shield against mud, water, fertilizer dust, and abrasive soil grit.

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

🚜 Agricultural Machinery Deployment & Usage Scenarios

• Heavy Disc Harrows & Cultivators: Essential extra heavy-duty hub bearing assembly for large-diameter tillage discs, rolling coulters, and stubble cultivators operating under intense soil resistance.

• High-Speed Tillage Implements: Direct fit replacement for high-speed compact disc harrows requiring a 35x185x113mm left-hand hub bearing unit.

• Severe Duty Farm Equipment: Ideal for heavy soil conditioning tools subjected to harsh dirt, slurry, wet fields, and continuous large-hectare operations.
