Philadelphia Gear

Local Service. National Support. Global Expertise.


The maritime world is increasingly complex, and so too are the demands placed on the equipment used in today’s marine industry. From fireboats used to combat disasters, to tugs guiding ever-larger container ships into safe harbor, to the LNG and oil tankers charged with keeping the world supplied with energy, or dredges helping to restore hurricane ravaged beaches, downtime cannot be tolerated. Simple as that.

At Philadelphia Gear, now part of Timken Power Systems (TPS), our goal is to help you with that burden so you can stay focused on your core mission. Regardless of your application, you can rely on our 125 years of experience to keep you operational.

Our one-stop-shop aftermarket solution is comprised of three major offerings (discussed in detail on the next page), and applies to all of TPS’s proprietary brands: Philadelphia Gear, Western Gear, WesTech Gear, DeLaval Steam Turbine, and GE Marine gearing.

Quick turnaround times for the inspection and overhaul of mission critical gearboxes is at the heart of our value proposition.

Onsite Technical Services (OTS)

Because Philadelphia Gear understands marine gearbox applications better than anyone, we know it’s not always feasible to remove a gearbox and send it to one of our service centers. That’s why we invented OTS. Designed to help our marine customers resolve their gearbox related issues while the vessel remains in the water, the OTS team is capable of a wide array of on-site solutions, including: removing and reinstalling equipment, rebuilding units in-place, re-boring housings, machining thrust faces, honing gear teeth, etc., and can be deployed globally on a rapid-response basis.

Customers now have the option of cutting a single P.O. for us to accomplish an agreed upon scope of work on a fixed-price basis. Simply put, our mission is the same as yours – to extend the longevity and reliability of critical rotating equipment as quickly and cost effectively as possible.
