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.
An engine utilizes a large number of bearings and engine-related parts. The requirements for comfort and convenience in the vehicle have diversified in the car market in recent years, resulting in roomier car interiors with reduced engine sizes. NSK offers compact and durable engine parts that lead the trend toward smaller engines.
