Description
06445700 – Belleville Washer .669″ × 1.535″ × 0.138″ (Genuine OEM Ariens / Gravely Part)
The 06445700 Belleville washer (.669″ ID × 1.535″ OD × 0.138″ thickness) is a genuine OEM Ariens / Gravely conical spring washer designed to maintain consistent clamping force, absorb shock, and compensate for vibration and thermal expansion in high-load assemblies.
Belleville washers are commonly used where constant preload is critical, such as idler arms, deck lift linkages, suspension points, brake systems, and drivetrain components. The spring-like design helps prevent fastener loosening and component wear during continuous operation.
Manufactured to Ariens and Gravely factory specifications, the 06445700 washer ensures proper fitment, correct spring rate, and long-term reliability in demanding mowing and commercial-duty applications.
