NEMA 9-7/16 C-Face Flange Dimension Unit

Module Feature

9-7/16" is defined by NEMA MG1 industry standard. It is the C-face flange outside diameter for NEMA 184TC frame induction motors. This standard is adopted by all NEMA motor manufacturers including Baldor, Marathon, ABB, Leeson, Allen‑Bradley. It ensures mechanical interchangeability between motor, gear reducer and close-coupled pump. This entry is only mechanical dimension specification and contains no electrical components.

Working principle

Passive mechanical standard. Defines flange outer profile, bolt circle reference and mounting footprint. Guarantees accurate alignment for flange coupling assembly. No electronic parts.

Onboard components

Not applicable, pure dimensional reference.

LED indicators

No built-in LED indicators.

Hardware self-diagnosis

Use caliper to verify actual flange OD, inspect flatness, check surface machining defects.

Programming software

No dedicated programming software.
