Roller Chain Sprocket Result Interpretation

Read the candidate’s classification and explanation together. A score helps rank results but does not by itself establish interchangeability or replace a required check.

Classification	How to use it
DROP_IN	The matcher identifies a direct replacement under the applicable checks. Review the technical snapshot and any warnings before selection.
FIT_OR_BETTER	A compatible candidate with an identified improvement under the applicable rules. Review the stated difference and requirements.
REQUIRES_MODIFICATION	A defined adaptation or conversion is needed. Review its details and the required components and operations.
CONDITIONAL	A possible candidate has unresolved requirements or missing proof. Confirm the items shown before treating it as a replacement.
REJECT	A known failure prevents the candidate meeting the applicable requirements. Review the explanation.

An input conflict or insufficient information is a search-level issue, not a candidate classification. Correct the input or add the requested information before interpreting the search outcome.

A full match percentage for available comparisons does not automatically make a conditional candidate a drop-in: the result can still have unresolved proof. Reference and discovery searches use the same result-class meanings.

Note

Final selection and installation remain subject to the application’s requirements, engineering review and the manufacturer’s current information.
