Generator End Brands: Cat, Kato, Marathon, Stamford & More
We regularly stock generator ends from major OEMs including Caterpillar generator ends, Kato generator ends, Marathon, Stamford, Leroy-Somer, Newage, and others. If you’re searching for specific configurations (for example, a 900 kW Marathon alternator or a 2000 kW Stamford generator end), contact our team and we’ll confirm availability and output requirements.
How to Choose the Right Generator End
To select the right unit, start with:
• Required output (kW / kVA) and electrical load profile
• Operating speed (900 RPM, 1200 RPM, 1800 RPM)
• Output voltage (e.g. 277/480, 346/600, 7200/12470) and phase (single vs three phase)
• Enclosure/mounting requirements and end-use environment
If you’re replacing an existing alternator, we can help cross-reference your current unit and confirm compatibility before you buy.
