Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material grade as the original collar, ensuring consistent clamping force and concentricity on the blade shaft.
- Direct Collar-to-Shaft Fit — Engineered to seat flush against the blade shaft assembly, delivering a secure, repeatable mount every time the blade is changed or serviced.
- Broad SP Series Compatibility — Confirmed fitment across SP303516, SP303520, SP303526, SP303530, SP605716, SP605720, SP605726, SP605730, SP605736, SP4, and SP6457 pavement and flat saws.
- Blade Stability Under Load — A properly seated outer collar keeps the blade locked on centerline during cutting, maintaining a straight, consistent cut line through asphalt or concrete.
- Critical Safety Component — The outer blade shaft collar is a blade-retention part; using a correctly dimensioned OEM collar reduces the risk of blade movement or detachment during operation.
The outer blade shaft collar is a blade-retention component that clamps against the saw blade on the outer face of the blade shaft, working in tandem with the inner collar to secure the blade firmly in position. When this collar is properly torqued, it prevents lateral blade movement and maintains alignment throughout the cut. A worn, cracked, or incorrect collar can allow the blade to shift during operation, resulting in uneven cuts, accelerated arbor wear, and a significant safety hazard to the operator.
