⚡ Structural Advantages & Heavy-Duty Performance

Extended Inner Ring Design: 21mm wide inner ring provides superior shaft seating area, preventing shaft deflection, vibration, and fretting corrosion under high torque.

Maintenance-Free Sealed Unit: Factory pre-lubricated with high-grade agricultural grease, eliminating daily field greasing routines while preventing lubricant washout.

Heavy-Duty Contact Rubber Sealing: High-performance contact rubber seals create a solid barrier against moisture, mud, abrasive soil, and fertilizer dust.

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