⚡ Structural Advantages & Heavy-Duty Performance

Extended Shaft Flange Architecture: Heavy-duty integrated 117mm flange with a 102mm extended length housing design ensures optimal torque transmission, superior rigidity, and zero alignment deflection under extreme soil drag.

Multi-Lip Cassette Sealing Technology: Advanced multi-lip cassette seals form an impermeable barrier against moisture, mud, abrasive soil grit, and organic fertilizer dust in deep tilling conditions.

Maintenance-Free Pre-Lubrication: Factory pre-filled with high-temperature agricultural synthetic grease, eliminating daily field maintenance and preventing lubricant washout.

Vacuum-Degassed GCr15 Chrome Steel Core: High-precision, double-row angular contact bearing internal geometry delivers exceptionally high radial and axial dynamic load capacity.

🚜 Agricultural Machinery Deployment & Usage Scenarios

Disc Harrows & Deep Tillage Equipment: Direct replacement flanged hub unit for heavy-duty disc harrows, stubble cultivators, and seedbed preparation tools requiring a 30x117x102mm unit.

High-Speed Seeders & Disc Openers: Essential hub bearing assembly for opener discs, rolling coulter units, and agricultural seed drills.

Severe Duty Tillage Tools: Ideal for soil conditioning machinery subjected to continuous shock loads and heavy soil impacts.
