⚡ Structural Advantages & Heavy-Duty Performance

• Double-Row Angular Contact Design: High-precision double-row ball geometry provides enhanced rigid bearing arrangement capable of supporting simultaneous radial and bi-directional thrust loads.

• Heavy-Duty Dual Rubber Contact Sealing: High-efficiency contact rubber seals (2RS / LLU / DDU) form an airtight defensive barrier against mud, moisture, fertilizer dust, and abrasive soil grit.

• Maintenance-Free Synthetic Pre-Lubrication: Pre-packed at the factory with high-grade wide-temperature agricultural synthetic grease, completely eliminating routine field servicing and lube washout.

• Vacuum-Degassed GCr15 Chrome Steel: Premium high-carbon chromium steel construction provides maximum dynamic load capacity and superior fatigue resistance against continuous operational torque.

🚜 Agricultural & Industrial Machinery Deployment

• Agricultural Implements & Seeders: Direct fit replacement bearing for planter openers, gauge wheels, coulter hubs, and soil preparation equipment requiring a 20x47x20.6mm double-row bearing.

• Industrial Drives & Gearboxes: Essential heavy-duty bearing unit for electric motors, agricultural gearboxes, pumps, and conveyor pulley assemblies.

• Severe Duty Power Transmission: Designed for demanding machinery operating under heavy soil drag, wet field slurry, and abrasive dirt exposure.
