⚡ Structural Advantages & Heavy-Duty Performance

Precision 29mm Square Inner Bore: Specially BROACHED 29mm square bore ensures non-slip power transmission on square harrow axles, eliminating shaft wear and fretting corrosion under continuous field drag.

Heavy Tapered Roller Load Capacity: Heavy-duty tapered roller architecture easily handles severe simultaneous radial shock loads and unidirectional axial thrust generated by angled harrow discs.

High-Purity GCr15 Chrome Steel: Premium high-carbon chromium steel with advanced heat treatment provides superior core toughness and surface wear resistance in harsh, rock-strewn field environments.

Optimized Raceway Geometry: Precision-engineered contact lines reduce edge stress and thermal buildup during peak seasonal tilling operations.

🚜 Agricultural Machinery Deployment & Usage Scenarios

Disc Harrow Gang Assemblies: Essential heavy-duty bearing unit for agricultural disc harrows, rolling coulter gangs, and stubble cultivators utilizing 29mm square shafts.

Deep Tillage & Soil Preparation Implements: Direct replacement bearing for heavy offset disc harrows, power harrows, and deep-ripping tillage equipment.

Heavy Square Axle Implements: Engineered for demanding agricultural tillage tools operating under extreme soil drag, mud, slurry, and abrasive soil grit exposure.
