Electrical Accessories

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. These days, we cannot even imagine a vehicle on the road without these components. Unlike household appliances, these parts are exposed to extreme temperatures and vibrations. Therefore, they are equipped with far more durable and reliable bearings. NSK's advanced bearing technology has revitalized the automobile industry with such items as a clutch pulley unit for alternators, which is an automotive power source.
