The Multiquip 0070506307 Bearing is a genuine OEM component designed for the DCA180SSJU and DCA220SSJ series super-silent diesel generators. As a direct OEM replacement, this bearing is manufactured to the exact specifications required by Multiquip, ensuring a correct installation without guesswork. Confirmed fitment spans the DCA180SSJU, DCA180SSJU4F, DCA180SSJU4F3, DCA220SSJ, DCA220SSJU, DCA220SSJU4F, DCA220SSJU4F2, and DCA220SSJU4F3 models, including 60Hz variants. Sourced directly through an authorized Multiquip parts channel, this is the same bearing used in original production.
Key Features
- OEM-Grade Load Tolerance — Manufactured to Multiquip's original radial and axial load specifications, maintaining the rotational integrity the alternator depends on.
- Drop-In Installation — Engineered to the same dimensional profile as the original, seating correctly into the bearing housing without machining or shimming.
- Broad DCA Series Fitment — Covers DCA180SSJU and DCA220SSJ super-silent generator variants, including 4F, 4F2, 4F3, and 60Hz configurations.
- Protects Alternator Output Consistency — A worn bearing introduces shaft runout that degrades alternator performance and risks winding contact; a correctly functioning bearing keeps the rotor running true.
- Verified Multiquip OEM Part — Part 0070506307 is the exact component specified for these generator models, eliminating the risk of cross-fitting an incompatible bearing.
A bearing in a diesel generator alternator supports the rotor shaft, allowing it to spin freely and concentrically inside the stator windings. When the bearing is in good condition, the rotor maintains its correct clearance and produces stable electrical output. As the bearing wears, it allows shaft deflection or vibration, which can cause uneven power output, increased heat, noise, and ultimately contact between the rotor and stator — damage that is far more costly than a bearing replacement. Replacing a worn bearing with the correct OEM specification part restores smooth, stable operation and protects the rest of the alternator assembly.
