💥 Construction Advantages & Heavy-Duty Performance

Relubricable System: Outer ring features integrated grease lubrication holes, allowing routine field maintenance flushing to purge contaminants and significantly extend bearing service life.

Heavy-Duty Multi-Lip Sealing: High-performance contact rubber seals create a solid, airtight barrier against moisture, mud, 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 under heavy radial stress.

Precision Shaft Alignment: Standard 1-1/2" round bore provides optimal shaft seating, minimizing fretting corrosion and vibration under severe field loads.

🚜 Agricultural Machinery Deployment & Usage Scenarios

Tillage Machinery: Heavy-duty disc harrows, plows, soil conditioners, and seedbed preparation equipment.

1-1/2" Shaft Implements: Direct fit replacement component for agricultural implements requiring a 1-1/2 inch round bore insert bearing with 33.324mm width.

Gang Shaft Overhauls: Essential replacement unit for agricultural gang shaft rebuilds and field repair operations.
