🚀 Engineering Advantages & Performance Benefits

Relubricable Structural Feature: External grease lubrication holes on the outer ring allow routine flushing during field maintenance, removing dirt and significantly extending bearing service life.

Triple-Lip Contact Sealing: High-performance contact rubber seals create a robust defense against abrasive soil, dust, mud, moisture, and crop residue.

High-Purity GCr15 Chrome Steel: Precision-machined from vacuum-degassed chrome steel (AISI 52100) for maximum fatigue strength and dynamic load-carrying capacity under heavy tillage stress.

Factory Pre-Lubricated: Pre-filled with high-grade, wide-temperature agricultural grease for smooth operation right out of the box.

🌾 Agricultural Machinery Applications & Use Cases

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

Farm Equipment Rebuilds: Ideal replacement unit for agricultural shaft rebuilds, gang bolt assemblies, and heavy field repairs.

High-Stress Field Operations: Engineered for continuous high-radial load and severe shock load environments.
