The Multiquip 042006309 Bearing is a genuine OEM component designed for MDR-9DYE, MDR-9D, and MDR-9GH ride-on trowels as well as the DCA25SSAI ultra-silent diesel generator. As a direct OEM replacement, this bearing is produced to the same tolerances and material specifications as the original, ensuring it seats and loads correctly within the machine's drive or rotating assembly. Sourced through DHS Equipment, the part is the correct factory part for these Multiquip models and an essential item for any scheduled maintenance or unplanned repair.
Key Features
- OEM-Grade Precision Tolerancing — Manufactured to the exact dimensional and load-rating specifications of the original bearing, ensuring correct press-fit, seating, and rotational performance in service.
- Drop-In Direct Replacement — Matches the original bearing's bore, outer diameter, and width so it installs directly into the existing housing without additional machining or shimming.
- Confirmed Fitment — Verified for MDR-9DYE, MDR-9D, and MDR-9GH ride-on trowels and the DCA25SSAI ultra-silent diesel generator.
- Sustained Load Capacity — A correctly specified bearing maintains smooth, low-friction rotation under the radial and axial loads these machines generate; a worn or failed bearing causes vibration, heat buildup, and accelerated wear to surrounding components.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip component, part 042006309, ensuring full compatibility with the original assembly design.
A bearing supports and guides rotating or oscillating shafts and assemblies by reducing friction between moving surfaces. In ride-on trowels, bearings are critical to the smooth operation of the blade drive and rotor assemblies — without them running true, blade pitch control and overall finishing performance degrade quickly. In generator applications such as the DCA25SSAI, bearings support the alternator rotor and engine output shaft, and a failing bearing can introduce vibration, noise, and ultimately lead to shaft or housing damage if not addressed promptly.
