🛠️ Structural Advantages & Heavy-Duty Performance

Relubricable System: Outer ring features grease lubrication holes to allow routine field maintenance flushing, purging contaminants and significantly extending bearing life.

Heavy-Duty Multi-Lip Sealing: High-performance multi-lip contact rubber seals create a robust defense against mud, water, abrasive soil, and fertilizer residue during continuous tilling.

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

Precision Bore Fitment: Standard 1-1/8" round bore provides optimal shaft seating and minimizes vibration and wear under severe field loads.
