Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's original engineering specifications, delivering the structural tolerances and material grade required for a load-bearing wall saw pivot component.
- Direct Bolt-On Replacement — Engineered to match the original mounting points and hardware interfaces on the WS440HF and WS440, so the assembly integrates without modification.
- Confirmed Wall Saw Fitment — Specifically compatible with the WS440HF and WS440 wall saws, eliminating guesswork when sourcing a structural replacement for this system.
- Restored Arm Articulation — A correctly functioning pivoting arm maintains precise blade track positioning throughout the cut; a worn or damaged assembly compromises cut accuracy and increases stress on surrounding components.
- Operator Safety Assurance — The pivoting arm is a structural element of the wall saw's track and blade positioning system; replacing it with a genuine OEM part maintains the mechanical integrity critical to safe cutting operations.
The Pivoting Arm Assembly is a core structural component of the wall saw's articulation system, allowing the saw head to be repositioned and angled correctly relative to the cutting surface. It serves as the mechanical link between the track-mounted carriage and the saw head, enabling the precise adjustments that wall sawing demands on vertical and horizontal concrete surfaces. When this assembly is bent, cracked, or worn at its pivot points, the saw head loses stable positioning, cutting accuracy deteriorates, and stress is transferred to the track and motor mount — making timely replacement with a genuine part essential to safe and accurate operation.
