Prevent unplanned downtime with new and replacement gearboxes from Philadelphia Gear®. Backed by over 130 years of design engineering and manufacturing expertise, Philadelphia Gear offers an array of flexible gearbox configurations to fit your specific footprint. We can create nearly any industrial gear arrangement, including parallel shaft, double helical, planetary / epicyclic, bevel helical, and more.
Maximize your throughputs with proven high-speed gearbox solutions from Philadelphia Gear®. We combine world-class engineering, long-term reliability, and a highly competitive initial cost to provide the industry’s leading gearbox design, manufacture, and repair.
As a founding member of the American Gear Manufacturer’s Association (AGMA) and a current member of the American Petroleum Institute (API), Philadelphia Gear leverages the unique skills and capabilities needed to match the extreme conditions of your most demanding applications.
For over 130 years, Philadelphia Gear has engineered and perfected a range of features to keep units performing at their peak efficiency while running at full capacity.
- Housings: Rugged design adds strength and rigidity, maintaining precise gear and bearing alignment. Custom cast or fabricated housings available.
- Bearings: Split, steel-backed, Babbitt-lined precision journal bearings have thrust faces engineered to account for axial load.
- Shafts: Machined from heat-treated, high-quality alloy steel. Oversized to maintain gear alignment and protect from overload.
- Gears: Designed, manufactured, and assembled with cutting-edge technology; through-hardened, or case carburized steel forgings; precision-hobbed and ground for accuracy and superior finish
- Pinions: Integral with shafts, precision-hobbed and ground; carburized or through-hardened versions per specifications
- Seals: Aluminum labyrinth seals prevent shaft leaks at extreme temperatures
- Dynamically balanced: Assures all rotating elements run smoothly at high speed
- API/instrumentation: Built to API standards as required, with a wide range of instrumentation options to satisfy any application requirements
The same number of cycles a conventional industrial gearbox would experience in years, a high-speed gearbox can experience in mere days. And often, these high-speed gearboxes are placed in harsh environments — from offshore in the North Sea to the frozen tundras of Canada.
Keep gearing failure at bay with Philadelphia Gear. Our experts build and integrate each element of our industrial gearboxes to withstand your application’s demands. In fact, we currently have units successfully operating with ratings up to 80,000 horsepower, shaft speeds up to 70,000 revolutions per minute, and pitch line velocities exceeding 35,000 feet per minute.
