Multiquip 0071906309 Bearing

The Multiquip 0071906309 Bearing is a genuine OEM component designed for DCA and MQP series generators, including models DCA36SPXU4F, DCA40SSKU4F2, DCA45SSIU4F, DCA70SSJU4F, DCA70USI2, DCA45SSIU4. As a direct OEM replacement, this bearing is sourced and supplied to the exact specifications used in original production, ensuring proper fit within the alternator or drivetrain assembly of your generator. Compatible across a broad range of Super-Silent, Ultra-Silent, and standby generator configurations, this part covers both standard and Tier 4 Final emissions variants in the DCA and MQP families.

Key Features

• Genuine OEM Construction — Manufactured to the same dimensional and load tolerances as the original bearing, maintaining correct shaft alignment and rotational performance within the generator assembly.
• Direct Drop-In Replacement — Engineered to the same bore, outer diameter, and width as the original, allowing installation without machining or adaptation.
• Broad Generator Family Coverage — Fits a wide range of DCA Super-Silent, Ultra-Silent, and MQP standby generator models, including DCA45SSIU4F, DCA70SSJU4F, DCA40SSKU4F, DCA70USI2, and MQP56 variants.
• Sustained Output Integrity — A correctly seated bearing keeps the rotor spinning true, protecting winding clearances and sustaining consistent power output under continuous or heavy load operation.
• Prevents Progressive Drivetrain Damage — A worn bearing introduces vibration and misalignment that can damage adjacent components; replacing it promptly with a correct OEM part stops that failure chain before it escalates.

A bearing in a generator serves as the precision interface between rotating and stationary components, allowing the rotor shaft to spin freely while supporting radial and axial loads. Inside a generator alternator assembly, the bearing maintains exact concentricity between the rotor and stator, which is critical for stable voltage output and long winding life. When a bearing begins to wear, it introduces vibration, heat, and rotor wobble — symptoms that can quickly progress to winding contact, shaft damage, or complete alternator failure if left unaddressed.
