NEMA 55/8BF Mechanical Dimension Unit

Module Feature

5-5/8 BF is NEMA standard imperial dimension notation. BF indicates bolt flange, 5-5/8 inch dimension commonly applied for NEMA motor C-face flange bolt circle or outer diameter. This standard is adopted by multiple motor manufacturers, ensures interchangeability of motors, gearboxes and pumps. This entry is only mechanical dimensional specification and contains no electrical components.

Working principle

Pure mechanical size specification without electrical function. It defines flange profile and bolt hole layout to guarantee alignment during flange coupling assembly. No electronic parts.

Onboard components

Not applicable, only dimension reference.

LED indicators

No built-in LED indicators.

Hardware self-diagnosis

Use caliper to verify actual dimension, inspect flatness and machining defects of flange surface.

Programming software

No dedicated programming software.
