Evidence scopeRead before ordering

What these pages represent

Every relationship comes from a manufacturer-published interchange/cross-reference source or verified successor notice.
Each exact model page cites the source and preserves its claim scope.
Multiple publishers can map different Sumitomo configurations to different target families.

What still needs verification

Ratio, torque, motor/input, bore or shaft, mounting dimensions and accessories.
Service factor, duty cycle, starts, shock load, lubrication and environment.
Any source-specific caveat such as mounting differences or required hardware changes.
