⚡ Structural Advantages & Heavy-Duty Performance

139mm Reinforced Flange & Extended Shaft Architecture: Heavy-duty integrated 139mm flange housing with a 104mm overall depth provides superior mounting rigidity, maximum axial load capacity, and zero alignment deflection under deep soil penetration.

Double-Row Angular Contact Bearing Core: Engineered with high-precision internal double-row ball geometry to deliver exceptional dynamic radial and axial thrust performance under intense continuous shock.

Multi-Lip Cassette Sealing Shield: Advanced multi-lip cassette rubber seals form a permanent barrier against moisture, mud, slurry, and abrasive soil grit contamination.

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