South Bay Diesel & Hydraulics, Inc.

What South Bay Diesel & Hydraulics, Inc. does

South Bay Diesel & Hydraulics, Inc. is a privately held industrial marine equipment distributor and consulting firm founded in 1987 and headquartered at 100 W. 35th St., Suite J, National City, California, with a secondary shop location at 1010 Coolidge Ave. The company supplies diesel engines, generator sets, transmissions, hydraulics, pneumatics, heat exchangers, bearings, and replacement parts to commercial fishing fleets, seafood and fishmeal plants, shipyards, and industrial plants, both domestically and internationally. It is an authorized distributor for four anchor specialty manufacturers — Craft Bearing, HydroControl, Durst Drives, and Xylem Standard-Xchange (formerly ITT Standard) — plus a broader secondary roster that includes Cummins, ZF, Parker, Eaton, Ingersoll Rand, Jabsco, Wagner, and others. The portfolio spans new products from these manufacturers alongside used, surplus, and rebuilt equipment, with parts offered at up to 60% off list price.

The underlying technology is non-proprietary: the company does not develop its own equipment but rather resells, sources, and consults on third-party industrial marine systems. Products include items carrying notable certifications such as Lloyd's Register Type Approval, US Department of Defense approval, ABS, US Coast Guard, and US Navy approval (via Xylem Standard Xchange heat exchangers and Craft Bearing shaft bearings), and Durst Drives features a licensed patented wet spline design (US Patent No. 7,152,711). The business model is sales-led and transaction-driven, combining one-time equipment and parts sales with consulting services and international container loading/export logistics coordinated through the San Diego port. With 1–10 employees, 37+ years of operating history, self-reported 100+ years of collective team experience, and documented customer reach across the US, Spain, Samoa, Korea, Ecuador, and Chile, the company operates as a small but internationally established specialist in a niche industrial trade.
