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.
Manual transmissions must adequately meet driver expectations of control by conveying a smooth, precise, and crisp feeling. Transmissions must also be compact, lightweight, and be able to deliver excellent fuel efficiency for the increased number of gears that are appearing in newer vehicles.
Automatic transmissions ensure smooth gear changes with minimal shift shock while operating under various kinds of driving conditions. A complex and extremely intricate form of technology known as friction control is ideal for efficiently conveying power from the engine and for smooth gear shifting.
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.
Hub unit bearings have to meet increasingly strict requirements that demand lighter weight, greater promotion of fuel efficiency, and enhanced module production systems. Along with the widespread adoption of antilock braking systems (ABS) to ensure stable maneuverability during braking, there is a growing need for our hub unit bearings with a built-in sensor.
