Multiquip 18574-004 Belleville Washer 3/8

The Multiquip 18574-004 is a genuine OEM Belleville Washer 3/8 designed for the SP2S20H flat saw. As a direct OEM replacement sourced from Multiquip, this washer is manufactured to the exact specifications required for correct clamping load and blade retention on SP2S20H series equipment. Keeping this component in serviceable condition is essential to safe and accurate cutting performance on flat saw applications.

Key Features

• OEM Spring-Load Precision — Manufactured to exact deflection and load specifications, ensuring correct clamping force is maintained under operating vibration and heat cycles.
• Direct OEM Replacement — Drops into the existing fastener stack on the SP2S20H without additional hardware or shimming, restoring the original torque retention behavior.
• Confirmed Fitment for SP2S20H — Verified for the Multiquip SP2S20H flat saw, giving you confidence that part number 18574-004 is the correct washer for your machine.
• Sustained Clamping Integrity — Belleville washers maintain axial preload even as bolted joints experience thermal expansion and contraction, helping fasteners stay properly seated during extended cutting runs.
• Blade and Arbor Safety — A correctly functioning Belleville washer is critical to blade clamping security; a failed or flattened washer can allow blade movement at the arbor, creating a serious hazard during saw operation.

A Belleville washer — also called a conical spring washer or disc spring — is a dished, ring-shaped component that generates a controlled spring force when compressed between a fastener and a mating surface. In a flat saw like the SP2S20H, Belleville washers are used where consistent clamping preload must be maintained despite vibration, heat, and repeated torque cycles. When a Belleville washer flattens out or fractures, it loses its spring function entirely, allowing fasteners to loosen and potentially compromising the secure retention of rotating components such as the blade arbor assembly.
