With the world’s leading Ball Screw, NSK has been contributing to industrial growth. NSK Ball Screws were developed through cutting-edge tribology (friction control technology), and NSK manufactures the largest volume in the world with its outstanding production and quality control techniques.
In FR vehicles, the engine power is transmitted to the rear differential gear via the propeller shaft. The fact that the center bearing used to support the propeller shaft is located on the vehicle’s exterior gives rise to a demand for optimum mud and turbid water resistance in addition to maintaining fast rotational speeds.
The Half Toroidal CVT is an innovative transmission that executes smooth, continuous gear ratio changes by changing the angle of the power rollers between the input disk and output disk.
NSK’s products are also used in a wide variety of vehicles ranging from motorcycles to all-terrain vehicles. The mechanical parts of motorcycles are exposed to rough running and high-rotation conditions, while all-terrain vehicles are utilized in a vast range of activities and environmental conditions. Bearings for these vehicles must be durable against water and mud.
Vehicles include a vast array of electrical accessories such as engine starters, air-conditioning systems for a comfortable riding environment, windshield wipers for safety, and oil-pressurized motors to assist power steering.
