Multiquip 180001 Outer Blade Shaft Collar Assembly

The Multiquip 180001 Outer Blade Shaft Collar Assembly is a genuine OEM component designed for the SP303516, SP303526, SP303530, and SP303520 Street Pro Series pavement saws. Sourced directly from Multiquip, this assembly ensures the blade shaft is properly retained and aligned to the exact tolerances required by your machine. It is a direct OEM replacement that installs into the blade shaft system without adaptation, keeping your saw performing to spec on every cut.

Key Features

• Precision Collar Tolerancing — Manufactured to OEM specification, this collar assembly maintains the exact shaft-to-housing fit needed to prevent blade wobble and shaft migration during operation.
• Direct OEM Replacement — Designed to match the original mounting interface on the blade shaft assembly, this part drops into position exactly as the factory component does.
• Confirmed Fitment — Compatible with SP303516, SP303526, SP303530, and SP303520 Multiquip Street Pro Series pavement saws.
• Blade Stability Under Load — A properly functioning outer blade shaft collar keeps the cutting blade stable and true through demanding pavement cuts; a worn or failed collar can cause blade deflection and uneven cutting.
• Blade System Safety — Correct collar retention is critical for blade containment at operating speeds; using a genuine OEM collar assembly ensures the shaft system maintains its designed integrity under full load.

The outer blade shaft collar assembly secures and positions the blade shaft within the saw's cutting head, acting as the structural interface that holds the shaft in precise radial alignment. When the collar is worn, cracked, or improperly seated, the blade shaft can shift under the lateral forces of cutting, leading to uneven blade wear, loss of cut accuracy, and potentially dangerous blade movement. Replacing this assembly with a genuine OEM part restores the shaft-to-housing relationship to its original designed tolerances, keeping the cutting system operating safely and accurately.
