Rotor & Shaft Assemblies

Ramco Electric Motors, Inc. manufactures a variety of rotor and shaft assemblies and subassemblies from rotors and shafts made in-house or supplied to us on consignment. We can cold-press shafts into rotors, heat shrink hot rotors onto cold shafts.

We have the finest OD grinding capability and experience, and can hold ± .0001" tolerances using our Studer S33 OD Grinder.

Ramco also uses Schenck balancing equipment on our close tolerance work.

All assemblies and subassemblies are inspected by our FARO ARM Coordinate Measuring Machine (CMM), as well as other high quality gauging.
