Precision Rotor Assembly & Remanufacturing
From raw laminations to final shaft insertion. Sotek is your nationwide partner for custom-built rotor components. For over 40 years, we have supplied rotor builds, tooling, and fabrication services for major OEMs. Whether you need a new fleet build or a complex rebar project, we handle it all in-house.
New Builds & Fleet Overhauls
Sotek specializes in volume OEM rotor manufacturing and large-scale repair programs. For new builds, all products are made in the U.S.A. ensuring quality control and supply chain stability.
For fleet repairs (like locomotive or rapid transit), we perform all critical processes in-house. This reduces turnaround time and ensures your remanufactured rotors meet or exceed original OEM specifications.
Rotor Rebar & Repair
We specialize in extending the life of your equipment. Our technicians perform precise rotor rebar services, replacing worn bars and end rings to restore electrical efficiency.
Shaft Replacement
A damaged shaft doesn't mean the rotor is scrap. We offer complete shaft removal and replacement services, pressing in new shafts to strict tolerance standards.
Lamination Refurbishment
We can salvage existing cores through lamination sand and recoat processes, or laser-cut entirely new laminations if the steel is beyond repair.
