HRC 58-62 Hardness & Induction Hardened Layer Superior Surface Protection: Heat-treated using high-frequency induction hardening to achieve a surface hardness of HRC 58–62 and an effective case depth of 2–3 mm. Heavy-Impact Resistance: Exceptional resistance to severe scuffing, high friction, and heavy crushing forces while maintaining a flexible inner core to prevent sudden snapping during heavy hammering or digging operations. Internal Grease Passage & Distribution Groove Effortless Maintenance: Includes an end-lubrication system with a central internal oil channel routing grease straight from the flange to the mid-shaft discharge port. Continuous Lubrication: Integrated axial distribution groove evenly spreads lubricant 360 degrees across the inner bushing surface, minimizing thermal wear and galling under continuous load.
