Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact 28mm outer diameter specification, ensuring consistent seating and correct load distribution within the assembly.
- Direct Drop-In Replacement — Matches the original component geometry for a straightforward installation into DCA-series ultra-silent generator assemblies.
- Broad DCA Series Compatibility — Fits DCA40SSAI, DCA40SSI, DCA45SSIU2, DCA60SSAI, DCA60SSI2, DCA45SSIU2-FEMA, and DCA45SSIU2-GEER generator models.
- Structural Integrity Under Load — A correctly fitted cup maintains proper bearing or shaft alignment, preventing premature wear on adjacent components and keeping generator output stable.
- Verified Multiquip Part Number — Sourced directly from Multiquip, so you receive exactly what the machine requires — no substitution or cross-referencing needed.
A cup of this type serves as a precision-fitted housing or race component within a rotating or sliding assembly, providing a controlled bearing surface that guides and supports movement while containing lubrication. When the cup is worn, cracked, or improperly seated, it allows unwanted play or misalignment in the assembly, which accelerates wear on surrounding parts and can lead to vibration, noise, or component failure. Replacing a worn cup with a correctly dimensioned OEM part restores proper clearance and contact, protecting the integrity of the overall drivetrain or support assembly in the generator.
