World-Class Industrial Gearbox Repair Since 1967

PAMCO’s Gearbox Replacement Experts Minimize Downtime. Since 1967, the industrial machine repair experts at PAMCO Machine Works have been providing gearbox repair, gearbox rebuild, and gearbox replacement services to ensure our customer’s industrial machinery stays up and running.

Gearboxes may be called by many different names: gear reducers, gear drives, speed reducers, cycloidal drives, epicyclic drives, harmonic drives, or speed increasers, but they all have one thing in common–sooner or later they need to be overhauled, rebuilt, or repaired.

We know downtime to our customers means lost $$$ and most shops today don’t have in house equipment repair capabilities. That’s where PAMCO comes in; we are both an emergency room for your gearbox repairs as well as a full-service machine shop that can make or fabricate just about any part your equipment and machinery may need.

Whether we send our personnel to work on-site at your facility, or we inspect and diagnose the failure here at our facility, you receive a detailed report of the findings. This includes the recommendation for repair and a firm, fair quote backed by a solid PAMCO Warranty.
