💥 Construction Advantages & Heavy-Duty Performance

Relubricable Feature: Outer ring is equipped with grease lubrication holes, allowing routine field maintenance flushing to purge debris and significantly extend bearing service life.

Heavy-Duty Multi-Lip Sealing: High-performance multi-lip contact rubber seals form 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 Bore Fitment: Standard 1-inch round bore provides optimal shaft seating and minimizes vibration and wear under severe field loads.

🚜 Agricultural Machinery Deployment & Usage Scenarios

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

1-Inch Shaft Implements: Direct fit replacement component for agricultural implements requiring a 1-inch round bore insert bearing.

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