⚡ Structural Advantages & Heavy-Duty Performance

• Maintenance-Free Sealed Protection: Factory pre-lubricated with high-grade wide-temperature agricultural grease, eliminating daily field greasing while preventing lubricant washout during heavy field operations.

• Heavy-Duty Multi-Lip Sealing: Advanced contact rubber seals create a solid barrier against moisture, mud, abrasive soil grit, and fertilizer dust contamination.

• Vacuum-Degassed GCr15 Chrome Steel: Manufactured from premium high-carbon chromium steel (AISI 52100) for maximum dynamic load capacity and superior fatigue resistance under continuous field shock.

• Precision Bore Alignment: Manufactured to exact 16mm metric tolerances for optimal shaft seating, smooth rotation, and minimal fretting corrosion.

🚜 Agricultural Machinery Deployment & Usage Scenarios

• Planters & Seed Drills: Essential replacement bearing for row crop planters, seed openers, gauge wheels, and disc coulter hub assemblies requiring a 16mm bore x 15mm width bearing.

• Tillage Equipment: Compatible with rotary cultivators, rolling basket assemblies, and seedbed conditioners.

• Farm Implement Drive Systems: Ideal for various agricultural seeding, planting, and tillage drive units requiring heavy-duty sealed protection.
