The Multiquip 044006309 Bearing 6309VV is a genuine OEM bearing designed for MDR-9DYE, MDR-9GH, and MDR-9D ride-on power trowels. As a direct Multiquip OEM component, it is manufactured to the exact tolerances required to keep rotating assemblies operating smoothly under the continuous loads typical of concrete finishing work. Sourced directly through an authorized Multiquip dealer, this bearing delivers the fit and specification your machine was built with from the factory. If you are servicing an MDR-9 series trowel, confirm your model code against 044006309 before ordering to ensure correct application.
Key Features
- Precision Tolerance, OEM Grade: — Manufactured to exact dimensional and radial-clearance specifications for the MDR-9 trowel series, ensuring proper load distribution and minimal play in the rotating assembly.
- Double-Sealed Construction (6309VV): — The VV designation confirms non-contact rubber seals on both sides, keeping grease in and contaminants out through extended finishing cycles.
- Direct-Fit for MDR-9 Series: — Confirmed fitment for MDR-9DYE, MDR-9GH, and MDR-9D ride-on trowels — drops into place using standard bearing installation procedures with no alteration needed.
- Sustains Smooth Blade Drive Performance: — A correctly functioning bearing keeps trowel drive components spinning true; a worn bearing introduces vibration, uneven blade pressure, and accelerated wear on adjacent drivetrain parts.
- Genuine Multiquip OEM Part: — Supplied as an authentic Multiquip replacement, so you can be confident the geometry, material grade, and load rating match the original specification for 044006309.
A 6309VV is a deep-groove ball bearing with double non-contact rubber seals, commonly used in rotating drive assemblies where consistent radial support is critical. In ride-on trowels like the MDR-9 series, bearings of this type support the rotating shafts that transfer power to the finishing blades — keeping everything centered, smooth, and in alignment. When a bearing wears or fails, operators typically notice vibration, noise, or uneven trowel blade action; left unaddressed, a failed bearing can cause damage to surrounding housings and drivetrain components, turning a straightforward service item into a more costly repair.
