Marine

Philadelphia Gear's history in the marine industry dates back to the early-20th century, providing gears, sprockets, and transmissions for U.S. ships during the First World War. Our role in this industry has grown since then, from ring and worm gearing for Navy destroyers in World War II, to our marine gear drives that power the icebreakers, warships and work boats of today.

Philadelphia Gear has been a supplier of main reduction gearing to the U.S. Navy and Coast Guard for over 70 years. The current active programs include the design and manufacture of the main propulsion drives for the San Antonio Class (LPD-17) of ships. In addition, our designs and manufactured couplings are used in the propulsion trains of Virginia Class (SSN774) of submarines. And our Synchrotorque® hyrdoviscous drive has proven to be a versatile addition to our marine efforts, functioning as wet clutches, wet brakes, torque control devices or variable speed drives.

Most recently, Philadelphia Gear has purchased the majority of General Electric Corporation’s non-nuclear marine gear product lines. This acquisition provides the right to intellectual property, equipment, and transition assistance to broaden existing capabilities to manufacture main reduction gear assemblies including the following classes of ships: USS Arleigh Burke (DDG 51), USS Freedom (LCS 1), and USS America (LHA 6).
