What We Supply

Replacement Alternator
Ends, Every Frame

01
New Alternator Ends
We supply new OEM-specification Stamford alternator ends across the full frame range. Every new end is built to Stamford's published specification — correct winding, voltage, frequency, and coupling configuration for your generator set.
  • HC / HCI series — 8 to 100kVA single bearing
  • UCI / UCM series — 10 to 250kVA two bearing
  • UCD / UCDI series — 250 to 500kVA two bearing
  • P / PI series — 500 to 2000kVA single bearing
  • All voltage and frequency configurations
  • SAE coupling and bell housing matched to your engine
02
Remanufactured Ends
We also supply fully remanufactured Stamford alternator ends — restored to OEM specification with new windings, bearings, and AVR. Remanufactured ends offer significant cost savings over new while delivering equivalent performance and reliability.
  • Completely rewound stator and rotor
  • New main and DE/NDE bearings fitted
  • New AVR module installed and set
  • Full output and insulation resistance test
  • HC, UCI, UCM, UCD, and P series available
  • Typically 30–40% lower cost than new
03
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
