Bearing Modification

Napoleon Engineering Services' modification program provides customers with flexible solutions for their bearing applications. Through the use of existing inventory, NES can modify standard products to fit the most specific application requirements. This approach reduces lead time and increases savings while significantly enhancing the bearing's performance in the application. NES is equipped to conduct precision and simple modifications, ensuring each bearing will operate at peak efficiency. Bearing modification is part of the industrial bearing CAR (Condition Analysis Reclamation) program.
