Extended Inner Ring Stability: 22.352mm wide inner ring design provides increased shaft support, effectively preventing shaft deflection, vibration, and fretting corrosion under high field torque.

Maintenance-Free Sealed Protection: Factory pre-lubricated with wide-temperature agricultural grease, eliminating daily field maintenance while preventing lubricant washout.

Multi-Lip Rubber Contact Seals: High-efficiency contact rubber seals form a solid barrier against moisture, soil particles, fertilizer dust, and crop residue.

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

🚜 Agricultural Machinery Deployment & Usage Scenarios

Planters & Seeders: Direct replacement component for Roanoke planting machinery, seed openers, gauge wheels, and metering assemblies.

Tillage & Cultivation Equipment: Essential component for rotary cultivators, soil conditioners, and light disc harrows.
