Multiquip L44610 Outer Bearing Cup

The Multiquip L44610 Outer Bearing Cup is a genuine OEM component designed for MQ62TK, QP4TKT, and MQ62TDD series trash pumps. As an OEM-sourced part, it meets the exact dimensional and material specifications set by Multiquip, ensuring proper seating and load transfer within the bearing assembly. This cup is a direct fitment replacement for the listed trash pump models, requiring no rework or modification to install. DHS Equipment stocks this part as an authorized Multiquip OEM replacement, so you can order with confidence that you are getting the correct component for your machine.

Key Features

• OEM-Matched Taper Geometry — Produced to the same cup taper angle and surface finish as the original, ensuring full roller contact and even load distribution across the bearing race.
• Drop-In Housing Fit — Engineered to the correct outer diameter for a secure press-fit into the bearing housing, eliminating slop or misalignment during reinstallation.
• Confirmed Fitment for MQ and QP Trash Pumps — Verified compatible with MQ62TK, QP4TKT, and MQ62TDD models, covering both the Kubota and Deutz diesel-powered variants in this pump family.
• Sustained Shaft Alignment Under Load — A correctly seated bearing cup keeps the pump shaft running true, supporting consistent impeller clearance and stable output pressure during demanding dewatering operations.
• Hardened Race Surface — The bearing cup race is manufactured from hardened steel to resist wear, pitting, and fatigue under the radial and thrust loads generated by trash pump operation.

The outer bearing cup is the stationary outer race of a tapered roller bearing assembly. It works in tandem with the bearing cone and rollers to support the rotating shaft, managing both radial loads from the impeller and any axial thrust generated during pump operation. When the cup becomes worn, pitted, or loses its press-fit in the housing, the bearing assembly develops play — leading to shaft misalignment, accelerated seal wear, vibration, and ultimately pump failure. Replacing a worn cup with a correctly toleranced OEM part like the L44610 restores proper bearing geometry and protects the surrounding components from secondary damage.
