Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact dimensional tolerances for the blade shaft assembly, ensuring correct seating and retention without guesswork.
- Direct Collar Replacement — Installs in the same position as the original inner blade shaft collar, requiring no modification to the shaft or housing during reassembly.
- Broad SP Series Compatibility — Fits SP605726, SP605730, SP605736, SP6457, SP605716, SP605720, and SP4 pavement and flat saw models.
- Blade Shaft Stability — A correctly fitted inner collar maintains proper blade shaft concentricity; a worn or missing collar can allow lateral blade movement, accelerating wear on bearings and the shaft itself.
- Cutting Safety Compliance — The inner blade shaft collar is a load-bearing retention component; using a correctly specified OEM part is essential to safe blade operation on pavement and flat-cut saws.
The inner blade shaft collar is a precision retention component that locates and secures the blade assembly on the saw's drive shaft. It works together with the outer collar and flanges to clamp the blade firmly in place, maintaining concentricity as the shaft spins at high RPM. When this collar is worn, cracked, or incorrectly sized, the blade can shift laterally during a cut — increasing vibration, accelerating bearing wear, and creating a hazardous condition for the operator. Replacing it with the correct OEM part restores proper blade clamping force and keeps the cutting system operating as designed.
