TOKAI CARBON Buliding a Future of Technology and Trust

Friction Materials

Friction materials regulate power transmission in industrial and construction machinery and in the brake and clutch parts of vehicles like motorbikes, trucks, buses and trains.

Friction Materials

Brakes and clutches may seem completely different, but they are in fact very similar. Brakes use friction to reduce speed, and clutches use friction to control power transmission. Both parts rely on friction materials to function. Tokai Carbon is a leading company in friction materials. We hold a big share in the large-sized motorcycle market, where power control is particularly challenging. We also manufacture the sliding materials—that is, materials developed to glide without any friction—used in hydraulic machine parts. Both friction and sliding materials are essential to smooth power transmission in machines and vehicles.

Applications

Wheel Loaders

Friction materials are an essential component in the brakes, clutches and turntables of wheel loaders.

Hydraulic Shovels

Oil lubricated sliding materials allow for smooth arm operation.

Industrial Robots

An internationally recognized breakthrough! Tokai Carbon’s friction materials are used in the electromagnetic clutch of industrial robots.

  • Machine Tools

    Tokai Carbon’s friction and sliding materials are durable even in harsh environments and support safe and efficient work.

  • Motorcycles

    Tokai Carbon’s products can be found in the brakes and clutches of motorcycles from Japan's four major manufacturers.

  • Agricultural Machinery

    The growth of the Asian population has sparked demand for Tokai Carbon's friction materials for agricultural machinery.

  • Commercial Vehicles

    Our friction materials keep the clutches and brakes of commercial vehicles working smoothly and safely, even with heavy use.

  • Railroads

    Tokai Carbon’s resin sliders are used to reduce cable wear and tear in pantographs, devices that transmit power to a train from overhead cables.

  • Conveying Machinery

    Conveying machinery relies on friction materials to shift gears smoothly and stop safely while receiving loads.

  • Ships

    Tokai Carbon produces friction materials in small batches of many varieties, including Toyoca FC for ship clutches.

Friction Materials Varieties

Sintered Metal Friction Materials

Sintered metal friction materials are a product of powder metallurgy. Metal powders like copper and tin are first mixed with friction modifiers like ceramic and powdered graphite lubricant and are then molded and sintered (made solid).
Tokai Carbon began manufacture of sintered metal friction materials in 1949. In 1978, after years of R&D, we were the first in the world to apply this technology to motorcycle brake pads. Very durable, our sintered metal friction materials are also used in the clutches and brakes of construction and agricultural machinery and in machine tools.

Paper Friction Materials

Paper friction materials are non-asbestos friction materials developed and sold by Tokai Carbon. They are available in a range of grades to fit a wide variety of applications, from parking brakes to heat and wear-resistant clutches.

Carbonaceous Friction Materials

Tokai Carbon's carbonaceous friction materials are (1) flat (μ-v & μ-P), (2) compatible with many oils, and (3) very durable and stable. They improve performance of products they are in.

Sliding Materials

Tokai Carbon produces materials with excellent sliding performance for hydraulic equipment. In the manufacturing process, we take advantage of the possibilities of powder metallurgy to combine ingredients differently for different uses.

Resin Materials

Various powders are combined with a binder (resin) in a textile base and then baked hard. The resultant material, which has excellent relative heat resistance, is used in the brake lining and disk pads of cars.

Woven Materials

Cloth pre-woven with fibers is impregnated with resin and baked hard. The resultant material is suitable for friction materials used in oil.

Soft Molds

Various raw materials are mixed with a rubber binder and baked hard. The rubber binder makes our soft molds flexible, so they are suitable for use in the drum brake of bicycles or washing machines.
