Gear Box Repair

NAMCO is proud to be able to make high-quality products, which meet or exceed your specifications. But sometimes, other manufacturers gearboxes fail and require overhaul/repair work. This is where our skilled technical staff can assist you in rebuilding the gearboxes to original specs, or in some cases, re-designing the unit for longer life and better operating conditions. Also, NAMCO designs custom gearboxes and power transmission equipment, if major changes are required.
