Carbon bearings used for electric water pumps mounted in electrified vehicles (xEVs). They have been developed applying our materials and tribology technologies built to produce cooling water sealing. These items adopt NOK’s original carbon materials, which exhibit excellent resistance against heat, wear, corrosion, and dry sliding. They contain no hard materials, such as glass fiber,…
Diaphragm couplings developed for aircraft gas turbine engines. This product absorbs displacement to ensure proper torque transmission. As machinery and equipment is growing in size and speed, couplings are expected to have lighter weight and lower bearing load. This requires this item to increase its abilities to absorb misalignment and enable durable dynamic balance during…
Used for equipment’s elastic joint sealing and displacement absorption. They excel in consistent displacement and corrosion resistance. Metallic bellows exhibit resistance against highly corrosive fluids and radioactive fluids. They have been developed as ideal sealing alternative to elastomer and gasket materials to be used for equipment running under high-temperature and high-pressure conditions.Actual applications range from…
Pressure accumulators, a mechanism that uses the compressibility of nitrogen gas. They are used for capacity correction and pulsation absorption in fluidic circuits. Accumulators are an essential function to enable the potential energy of fluids to act effectively, and maintain high-accuracy operations of oil, water and other fluidic circuits in a safe and economic manner.…
Electromagnetic valves used mainly for oil pressure control and gas flow control for automobiles. With built-in resin components, they are compactly designed and highly reliable. Our actuators, mainly used for oil pressure control and gas flow control for automobiles, excel in resistance to pressure. Incorporating resin components to a large extent, they are compact, lightweight,…

Our solenoid valves, mainly used for oil pressure control for automobiles, excel in resistance to pressure. Incorporating resin components to a large extent, they are compact, lightweight, high-performance solenoids. These…
With rubber/plastic materials built in (by molding), these FPCs are equipped with waterproof and impact-resistance (protection) functions. There are two major applications for precision rubber/plastic products: built-in precise functional components of HDDs; and materials built into internal and external parts of HDDs and smartphones to increase water- and dust-proof performance. Applying our development/manufacturing technologies related…
Documents and Catalogs Single-sided FPCs Single-sided FPCs can be bent freely and help effectively use the scape of mounting on their surface. They endure repeated bending and help reduce the space required for wiring on their surface. These are standard FPCs with a layer of silver foil on the polyimide film-covered side. With a simple…
NOK provides rubber vibration and sound isolators for automobiles and precision information devices. Original programs developed by NOK can be used to analyze and tune the products. NOK’s high-quality rubber vibration isolators with distinctive features are produced on the solid foundation of the technical expertise, vast experience and remarkable achievements of Freudenberg, the top rubber…
