Your high-stakes marine business demands high-quality gear drive performance. Keep your commercial marine vessels running reliably with mission-critical gearing applications, premier aftermarket service, and unmatched 24/7 support from Philadelphia Gear.
With complete warranty coverage on workmanship and material for any gear drive we service, including those from other manufacturers, we’ve set the standard in dependability — on land and sea — for more than 130 years. And now, as part of the Timken Power Systems network, we can also return your motor, coupling, or bearing to its original OEM specifications.
