Using Iron Rubber—high in mechanical strength, abrasion resistance, oil resistance, and weather resistance—NOK’s power transmission belts and conveyor belts are utilized as next-generation belts in many industries. The use of Iron Rubber has enabled the production of timing belts of any length without using rubber dies for each belt. As a pioneer in the field…
Characteristics Cushioning components Buffer components are used in automobiles, motorcycles, agricultural machines, power tools, industrial robots, general industrial machines, and so on. Slide components Slide components are used in bearings of automobiles, construction machines, agricultural machines, railway vehicles, and general industrial machines. These components have high wear resistance, high durability, and high vibration absorption. Seal…
Synthetic-rubber-based industrial functional components are listed here. NOXTITE (brand name for NOK’s polyacrylate rubber), fluororubber, silicone rubber, ethylene-propylene rubber, chloroprene rubber, nitrile rubber, and many other types of synthetic rubber are mixed to suit the purpose of use. These components are used as diaphragms in vehicles’ emissions-control systems, the bellows and boots of joints and…
General-purpose seal technology Seals are indispensable sealing devices used in automobiles, airplanes and other vehicles, construction machines, equipment at petrochemical plants, home appliances, and various other machines. NOK offers a wide variety of seal products of very high reliability, including oil seals, based on its constant and focused research on materials, workings, and design. MORE…
A hybrid seal is a combination of a magnetic fluid seal, a weld metal bellows, and a rotary joint. The combination achieves compact design and improved maintainability. This compact, highly-maintainable product is supplied by EAGLE INDUSTRY, which has some of the leading mechanical seal technology in the world. It combines a magnetic fluid seal, a…
Magnetic fluid seals are seals using magnetic fluids, which have the characteristic of being drawn to magnets. Unlike conventional oil seals and mechanical seals, magnetic fluid seals are seals that maintain clean sealing performance achieved by fixing a magnetic fluid around the rotating shaft with a magnet to make fluid O rings.They are used as…
Kalrez is chemical-proof synthetic rubber. It maintains the properties of rubber even at high temperatures. The key strengths of Kalrez are that it has both the elasticity and seal characteristics of an elastomer and the chemical resistance and thermal stability of Teflon. Kalrez produces a small amount of gas in a vacuum and exhibits high…
ACTISEAL is a static elastic metallic seal. It has properties that conventional gaskets, metal O rings, or rubber O rings do not have. With its special structural design, the elastic metallic gasket has low-load characteristics and capabilities to follow deformation, which conventional gaskets and metallic O rings do not have. For more information of the…
A brush seal includes bristles and two plates, and ensures highly-efficient airtightness. When mounted in an engine, the brush seal keeps up with changes in clearance between the stator and rotor and in eccentricity. With the excellent airtightness, the brush seal significantly improves the power and fuel efficiency of the engine. Brush seals have been…
A segment seal is a gas seal primarily for use in the main shaft of an aircraft engine. Since it has high reliability, the segment seal is also used in rockets. The segment seal has been developed mainly for the main shaft of an aircraft engine, with technical support provided by Koppers Inc., U.S. This…
