Products for use in automobiles

Oil seals

  • Oil seals
  • Oil seals are functional parts used to seal oil. Composed of synthetic rubber, metal rings and springs, they prevent leaks of lubricants from gaps within machines and bearings. They also prevent the entry of dust from the outside.

    Major applications

    Automobiles, aircraft, marine vessels, railroad vehicles, construction machinery, agricultural machinery, steel mills, industrial robots, office machinery, home electronic appliances, etc.

  • Major applications

    Automobiles, aircraft, marine vessels, railroad vehicles, construction machinery, agricultural machinery, steel mills, industrial robots, office machinery, home electronic appliances, etc.

O rings

  • O rings
  • O rings are O-shaped ring gaskets. They are appropriately compressed by fitting into grooves, and prevent leaks of various fluids, including oil, water, air and gas.

    Major applications

    Automobiles, construction machinery, agricultural machinery, piping joints, water-proof cell phones, etc.

  • Major applications

    Automobiles, construction machinery, agricultural machinery, piping joints, water-proof cell phones, etc.

Dust covers

  • Dust covers
  • Dust covers are functional parts that protect ball joints used in the joint mechanisms of suspensions and steering in automobiles. They prevent leaks of enclosed grease to protect the smooth surface of the ball joint as well as the entry of foreign matter such as dirt and water.

    Major applications

    Automobile suspension and steering, etc.

  • Major applications

    Automobile suspension and steering, etc.

Rubber vibration/sound isolators

  • Rubber vibration/sound isolators
  • A range of vibration/sound isolators are available, including torsional dampers to reduce crankshaft vibration in car engines, and center bearing supports to absorb and isolate vibration by supporting the propeller shafts of rear-wheel drive cars (FR, 4WD) such as passenger cars and trucks.

    Major applications

    Crankshafts of car engines, propeller shafts of rear-wheel drive cars (FR, 4WD), etc.

  • Major applications

    Crankshafts of car engines, propeller shafts of rear-wheel drive cars (FR, 4WD), etc.

Solenoid valves

  • Solenoid valves
  • Solenoid valves are electromagnetic valves used for controlling the pressure and flow volume of automobiles. We have achieved designs with superior durability while keeping products small and lightweight. We meet the requirements of all types of applications, including on-off solenoids, duty solenoids and linear solenoids.

    Major applications

    Automobile engines and transmissions, shock absorbers, car air-conditioning, etc.

  • Major applications

    Automobile engines and transmissions, shock absorbers, car air-conditioning, etc.

Double-sided FPCs

  • Double-sided FPCs
  • Double-sided FPCs have circuits on both sides. Compared to the single-sided version, they allow for more complex wiring, and contribute to downsizing and weight reduction through the mounting of parts on both sides. They are suitable for a variety of designs because they are freely bendable.

    Major applications

    Automobiles, digital cameras, smartphones, medical devices, etc.

  • Major applications

    Automobiles, digital cameras, smartphones, medical devices, etc.
