The Multiquip EM50449 Ball Bearing 6309 is a genuine OEM Ball Bearing 6309 designed for QP3TZ trash pumps and MVH308DZ reversible plate compactors. Sourced directly from Multiquip, EM50449 meets the original design tolerances and load ratings specified for these machines. This bearing is a direct OEM replacement, confirmed compatible with both the QP3TZ and MVH308DZ model lines.
Key Features
- OEM-Grade Load Tolerance — Manufactured to the precise radial and axial load ratings required by the 6309 specification, ensuring the bearing performs under the high-speed, high-load conditions of trash pump impellers and plate compactor exciter shafts.
- Drop-In Dimensional Fit — Matches the original bore, outer diameter, and width of the factory-installed bearing, allowing installation without machining or modification to the bearing housing.
- Confirmed Fitment — Verified for use in QP3TZ trash pumps and MVH308DZ reversible plate compactors, covering two demanding equipment families in the Multiquip lineup.
- Sustained Rotation Under Load — A correctly seated 6309 bearing maintains smooth shaft rotation and reduces heat buildup; a worn bearing causes vibration, overheating, and accelerated damage to surrounding components.
- Genuine Multiquip OEM Part — Supplied under the Multiquip OEM program, part number EM50449 carries the same quality assurance as the bearing installed at the factory.
A ball bearing serves as the rotating interface between a spinning shaft and its stationary housing, carrying the radial and axial forces generated during operation while allowing the shaft to turn freely and smoothly. In a trash pump, the bearing supports the impeller shaft against the hydraulic loads created during pumping; in a plate compactor's exciter assembly, it withstands the continuous vibration forces that drive compaction. When a ball bearing wears, develops pitting, or loses its grease film, the result is increased noise, heat, and vibration — and if left unaddressed, shaft damage and equipment failure.
