Multiquip 0071906311 Bearing

The Multiquip 0071906311 Bearing is a genuine OEM component designed for DCA and NGA series super-silent and ultra-silent diesel generators, including DCA70SSIU, DCA85SSJU, DCA100SSVU, DCA100SSJU, DCA70SSJU, DCA85USJ, and NGA100SSPUL models. As a factory-sourced part, it meets the original design tolerances required to keep these generator sets running at spec. DHS Equipment supplies this bearing direct, so you can confirm fitment by model code and order with confidence. This is the correct replacement for a wide range of Multiquip super-silent and ultra-silent generator configurations, including 50 Hz and 60 Hz variants.

Key Features

• OEM Precision Tolerancing — Manufactured to the original dimensional and load-rating specifications that Multiquip engineers require for proper alternator and drivetrain operation in these generator sets.
• Drop-In Installation — Matches the original mounting configuration exactly, so the bearing seats and preloads correctly without shimming or modification to the housing.
• Broad Generator Fitment — Confirmed for DCA70, DCA85, DCA100, DCA56SPX, and NGA100 series models, covering super-silent, ultra-silent, and diesel alternator configurations across multiple voltage and frequency variants.
• Sustained Alternator Performance — A worn or failed bearing introduces vibration, heat, and misalignment that degrade output quality and accelerate alternator wear; replacing with this part restores smooth, stable operation.
• Genuine Multiquip Part — Sourced directly from Multiquip's OEM supply chain, ensuring the material grade and dimensional accuracy match the unit's original build specification.

A bearing in a diesel generator set supports the rotating shaft of the alternator, maintaining precise alignment between the rotor and stator while minimizing friction under continuous load. When a bearing begins to fail, the resulting play and heat buildup can cause irregular voltage output, increased mechanical noise, and accelerated wear on surrounding components. Replacing the bearing at the first sign of wear — roughness, noise, or elevated temperature — protects the alternator and keeps the generator producing clean, stable power.
