Direct answer
For a Ninja CREAMi NC301, the current official replacement outer bowl is part 724KKU300. SharkNinja lists NC301 by exact model number, along with specific NC299, NC300 and CN300-series variants. Do not substitute the 811KKU500 Deluxe outer bowl or 394KKU700 Scoop & Swirl outer bowl; those parts have separate official model lists.
Compatibility ledger
OFFICIAL RECORDS| Item or model | Compatible system | Verdict | Research note |
|---|---|---|---|
| 724KKU300 / Original CREAMi outer bowl | NC301 and the exact models in Ninja's current list | Fits | NC301 appears by exact model number on the official 724KKU300 product page. |
| Listed NC301 variants | NC301C, NC301HNV, NC301HRD, NC301HRG, NC301HSL, NC301HWH, NC301RGBBB and NC301WHBBB | Fits | Each suffix is explicitly included in the current manufacturer record. |
| NC351 and unlisted CREAMi variants | Not established by the 724KKU300 page | Verify model | Sharing a pint family does not prove that the processing bowl and lock geometry are the same. |
| 725KKU300 / outer bowl lid | NC301 and the lid's separately listed models | Fits | This is the matching lid, not the outer bowl itself; the two part numbers are not interchangeable. |
| 811KKU500 / Deluxe outer bowl | Listed NC500 and NC501-series machines | Does not fit | SharkNinja publishes a different part and model list for the Deluxe processing system. |
| 394KKU700 / Scoop & Swirl outer bowl | NC700 and NC701 | Does not fit | This is the dedicated NC700-series bowl, not an NC301 replacement. |
The complete 724KKU300 model list
As checked on August 11, 2026, SharkNinja lists CN301CCO, CN301CO, CN305A, NC299AMZ, NC300, NC300C, NC301, NC301C, NC301HNV, NC301HRD, NC301HRG, NC301HSL, NC301HWH, NC301RGBBB, NC301WHBBB and CN302CCO. Treat that exact list as the evidence boundary rather than expanding it to every machine marketed as a CREAMi.
Bowl, lid and pint are three different checks
Part 724KKU300 is the processing outer bowl. Part 725KKU300 is the outer bowl lid, while XSKPLID2CD identifies a set of 16 oz ingredient pints and storage lids. A marketplace listing can mention NC301 while selling only one of these components, so confirm both the component name and part number before ordering.
Why Deluxe and Swirl bowls are not substitutes
SharkNinja assigns 811KKU500 to named NC500 and NC501 Deluxe machines and 394KKU700 to NC700 and NC701 Scoop & Swirl machines. Those separate official records show that the shared CREAMi name does not make the processing bowls universal across Original, Deluxe and Scoop & Swirl systems.
A safe purchase checklist
Read the rating label on the machine, copy the complete model including its suffix, look for 724KKU300 in the listing, and confirm that the seller is offering the outer bowl rather than only the lid or pint. For a third-party replacement, require an explicit NC301 compatibility statement and a usable return policy; photos and approximate dimensions alone do not verify fit.
Evidence boundary
This guide reports current US manufacturer compatibility records. FitCheck Lab did not physically test the Ninja part or any third-party replacement, and the official part record does not validate an unbranded item that merely copies the 724KKU300 number.
