Frame Size Matching
Every Stamford alternator end we supply is matched to your existing generator set by frame, kVA rating, voltage, frequency, and coupling. We use your nameplate details or serial number to source the exact-specification replacement — no guesswork.
  • Matched by Stamford frame designation (e.g. UCI274E)
  • Matched by kVA — standby and prime power rating
  • Matched by output voltage and winding configuration
  • Matched by frequency — 50Hz or 60Hz
  • Matched by SAE disc and engine bell housing size
  • Serial number lookup available for exact-spec confirmation
