Our Premium Heavy‑Duty Arm Bushing (Part Number: 14546058 / VOE14546058) is a precision‑manufactured hardened steel sleeve for excavator boom, stick and bucket linkage pivot joints. Installed inside arm bores, it serves as a sacrificial wear part protecting pins and structural frames from friction damage. Designed for medium‑duty VOLVO excavators, it ensures stable zero‑play hinge movement under heavy‑load digging, trenching and lifting conditions.
Case‑Hardened High‑Carbon Chromium Alloy Steel: Forged alloy steel with deep surface hardening, resisting abrasive wear and impact damage from construction‑site grit and dust.
Internal Cross‑Groove Lubrication Channels: Precision‑machined grease grooves distribute lubricant evenly across the friction surface, eliminating dry‑metal contact and seizure.
Micro‑Honed Precision Dimensions: Strict tolerance control enables perfect press‑fit installation while maintaining optimal clearance for pivot pins.
High Impact & Shock Resistance: Tough inner structure withstands sudden hydraulic‑load impacts, preventing cracking or breakage under continuous heavy‑duty operation.
