Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the same conical load specifications as the original, ensuring consistent clamping force and spring tension across the blade assembly.
- Direct Drop-In Replacement — Sized at 1/2 x 1-1/4 to match the original washer profile, allowing straightforward installation without machining or shimming.
- Broad SP Series Compatibility — Fits a wide range of Street Pro pavement saws and flat saws, including SP303516, SP303520, SP303526, SP303530, SP605716, SP605720, SP605726, SP605730, SP605736, SP6457, and SP4.
- Consistent Blade Clamping Performance — A properly functioning Belleville washer maintains the correct axial load on the blade arbor; a worn or collapsed washer can lead to blade slippage and uneven cutting depth.
- Blade Safety Relevance — Correct spring tension in the blade clamping stack is critical for safe saw operation; replacing a fatigued Belleville washer helps maintain proper blade retention under load.
A Belleville washer — also known as a conical spring washer or disc spring — is a curved, dome-shaped washer designed to exert a controlled axial load when compressed. In pavement and flat saws, it is used in the blade arbor clamping assembly to maintain consistent pressure on the blade flange, compensating for thermal expansion and vibration that would otherwise loosen the blade during cutting. When a Belleville washer fatigues, flattens, or fractures, the clamping stack loses its preload, which can result in blade wobble, inconsistent cut depth, or unsafe blade retention. Replacing it with a correctly sized OEM washer restores proper clamping tension and keeps the blade tracking true through asphalt and concrete.
