Serving all of the major U.S. transit authorities—and Japan’s high-speed bullet train.
As more and more commuters turn to public transportation, NTN is always working to provide new and improved ways to assist local and worldwide transportation systems. NTN supplies a large number of tapered roller bearings for gearbox, wheel, and journal applications, as well as ceramic-coated bearings for traction-motor applications.
NTN built its foundation in the rail industry on tapered roller bearings for gearbox applications. These tapered roller bearings are made at NTN-Bower® facilities in the United States. They are designed to support both axial and radial loads, as well as to withstand excess vibration produced by small and large gears. Our standard case-carburized steel offers a forty percent longer bearing life, helping to make NTN the best in the business.
Our diverse product line also features insulated bearings specifically designed for trail-traction motors. These ceramic or resin-coated bearings counteract damage caused by electrical currents in rail-car motors. NTN offers insulated bearings in a wide variety of bore diameters.
The NTN-Bower® brand is a top choice for major transit authorities across the country. From New York City to Los Angeles and Orlando to Philadelphia, the largest, most stringent organizations demand our bearings for their fleets.
OEMs in the bus market turn to us because NTN-Bower products are backed with the most stringent quality standards in the industry. Then comes our record of high customer satisfaction and our dedication to R&D, which translates into unique solutions, proprietary technologies, and bearing products that provide the most durability, the longest life, and the highest performance.
