LIEBHERR BRONZE BUSHING FOR EQUIPMENT ARM PIN

Ask about product

This is a precision-machined leaded-bronze bushing functioning as a articulating bearing at the rotating joints of the work equipment, operating directly against the steel pin and the bore in the arm or bucket. Its critical role is to absorb vibration and shock loads during excavation; the bronze material allows contaminant particles to embed themselves in the metal matrix, preventing aggressive abrasion and pin fatigue fracture. The primary wear mechanism involves bore ovalization and surface scoring when lubrication is absent, leading to joint clearance and the characteristic ‘clunking’ noise when changing dig direction. Planned replacement of bushing pairs is substantially less expensive than repairing a damaged bore, which under neglect loses geometry and requires costly honing or replacement of the entire structural member. Regular inspection of lubrication grooves and replacement at first signs of wear prevents failures that could immobilize the machine for multiple days.
