The Multiquip 16533 is a genuine OEM Key 5/16 x 5/16 x 7/8 designed for the WRS5200 ride-on roller screed. As a direct OEM replacement sourced through Multiquip's authorized parts program, 16533 delivers the exact dimensions and material grade required to maintain proper torque transfer on the WRS5200 drivetrain. Confirm your model code before ordering to ensure this key matches your specific shaft and keyway configuration.
Key Features
- OEM-Specified Dimensions — Manufactured to the exact 5/16 x 5/16 x 7/8 profile, ensuring correct engagement depth and shear tolerance for the WRS5200 shaft assembly.
- Direct Shaft Keyway Fit — Seats cleanly into the keyway slot without filing or shimming, maintaining the proper interference fit between shaft and hub.
- WRS5200 Compatibility — Verified fitment for the Multiquip WRS5200 ride-on roller screed series; check your machine's parts diagram to confirm the correct keyway location.
- Torque Transfer Integrity — A correctly sized key locks the rotating component to the shaft so power is transmitted without slippage, keeping screed output consistent across the full pass width.
- Genuine OEM Quality — Produced to Multiquip's material specification, so hardness and dimensional tolerance match the original component — critical for a small part that carries significant mechanical load.
A shaft key is a small, precisely machined component that sits in a slot — called a keyway — cut into both a shaft and the hub of a rotating part such as a pulley, sprocket, or drum. It creates a positive mechanical connection between the two, so rotational force from the shaft is transferred directly to the attached component rather than allowing it to spin freely. When a key wears, shears, or works loose, the driven component loses its positive drive, causing slippage, erratic rotation, or complete loss of function in the assembly it serves. On a ride-on roller screed like the WRS5200, a failed key can interrupt consistent roller speed and compromise the quality of the finished concrete surface.
