Over 100 bearings are used on a single automobile. In addition to hub bearings, NTN boasts a prominent global share in constant velocity joints (CVJ) and similar products that convey motive power from the engine.
Electric vehicles (EV) are expected to contribute towards environmental preservation and effective use of resources. NTN has commercialized bearings dedicated for EV motors and has also been developing many EV system products starting with the In-Wheel Motor System.
Bearings for railway journals that require a high reliability. NTN’s bearings are used on high speed railways in every country of the world and maintain safety for trains travelling in excess of 300 km per hour.
The demand for wind turbines is increasing as a means of renewable energy. NTN not only provides extremely large size bearings larger than 2 meters in diameter but also proposes the total package up to systems that achieve safe machine operation.
Construction and mining machinery that operates in a harsh environment. NTN bearings have a high performance and reliability as well as contribute towards safe and reliable work performance.
Agricultural machinery used under harsh conditions starting with a muddy water environment. NTN provides bearings that have a long lifespan, are highly reliable and are economical.
Bearings for NTN machine tools that support precision processing on a sub-micron level and ultra-high speed rotation. Our advanced design and material technology has made it possible to withstand centrifugal forces and frictional heat.
Bearings used for rotational sections on office machinery including printers and photocopiers. In addition to ball bearings with superior heat resistance, NTN provides clutch products and plastic sliding bearings with superior friction and wear properties.
Bearings for steel manufacturing machinery that must be water resistant at a high load and high temperature. NTN supports steel plants that operate 24 hours a day non-stop with its high durability bearings.
Bearings for paper manufacturing machinery that desire a high-mix high-variety in a series of operation stages to support an increase in speed and heat resistance, etc. NTN meets these needs and contributes towards improved operating rates and reductions in maintenance costs for equipment by increasing their lifespan.
Food manufacturing lines that require a clean, safe and secure environment. Starting with bearings that do not use oil or grease, NTN provides plastic bearings, slide screws and parts feeders, etc.
NTN provides high quality bearings from small bearings for dentistry that rotate in excess of several hundred thousand times per minute to bearings for high precision CT scanners that have an extremely large shape exceeding 1 meter. Furthermore, we possess technology for magnetic bearings used with auxiliary artificial heart pumps.
Bearings for rocket turbo pumps and jet engines on airplanes that require an extremely high level of technology. NTN performs special processes that have acquired customer certification and also performs thorough quality control including ultra-precision machining in a constant temperature and clean environment.
Starting with bearings for precision equipment, NTN also provides precision equipment for such as linear modules and parts feeders manufactured using technology accumulated from the development of bearings.
Robots that require accurate and stable operation. NTN provides bearings for robots that fulfill high precision tasks and have both a high rigidity and are used in high pressure.
Superior durability and stability at low torque are required for bearings used on power generators and motors, etc. NTN proposes bearings that include the development and proposal of lubricants (grease).
NTN provides bearings that can even be used in a vacuum due to surface processing technology and special lubricants. Vacuum bearings from NTN achieve stable rotation even in ultra-high vacuums at 10-10 Pa.
Gearboxes used in various applications for industrial machinery. NTN selects the bearing after matching every requirement, such as improved performance and miniaturization of gearboxes.
