The Multiquip 500365 Shaft Paddle 50" SM-80 is a genuine OEM component designed for the SM-80 series mixer. Sourced directly from Multiquip, this paddle shaft is manufactured to the exact dimensions and material specifications required for correct installation and consistent mixing performance. If you're servicing or rebuilding an SM-80 mixer, part number 500365 is the correct replacement to restore full operation. Confirm your model code against the SM-80 fitment before ordering to ensure a direct drop-in replacement.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the shaft delivers the torsional strength needed to drive mixing loads without flex or premature fatigue.
- Direct SM-80 Fitment — Engineered specifically for the SM-80 mixer, with the correct shaft length, paddle configuration, and connection points to install without alteration.
- Full Mixing Efficiency Restored — A worn or damaged paddle shaft causes uneven mixing, increased motor load, and inconsistent output; replacing with 500365 brings the drum back to full mixing capacity.
- Paddle and Shaft in One Assembly — The combined shaft-and-paddle design means fewer separate components to source, simplifying the service process and getting the mixer back in operation faster.
- Durable Under Continuous Load — Built to withstand the repetitive stress of mortar, plaster, and concrete mixing cycles that SM-80 equipment is routinely subjected to on the jobsite.
The paddle shaft is the central rotating component inside the mixer drum that agitates and blends material throughout the mixing cycle. It transmits rotational force from the drive system through to the paddles, which fold, lift, and turn the mix to achieve a uniform consistency. When the shaft is bent, worn, or broken, mixing becomes incomplete or stops entirely — leading to poor material quality and potential drive system strain. Replacing a damaged shaft promptly protects both the finished mix and the surrounding drivetrain components.
