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.
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.
Friction materials are an essential component in the brakes, clutches and turntables of wheel loaders.
Oil lubricated sliding materials allow for smooth arm operation.
An internationally recognized breakthrough! Tokai Carbon’s friction materials are used in the electromagnetic clutch of industrial robots.
Tokai Carbon’s friction and sliding materials are durable even in harsh environments and support safe and efficient work.
Tokai Carbon’s products can be found in the brakes and clutches of motorcycles from Japan's four major manufacturers.
The growth of the Asian population has sparked demand for Tokai Carbon's friction materials for agricultural machinery.
Our friction materials keep the clutches and brakes of commercial vehicles working smoothly and safely, even with heavy use.
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 relies on friction materials to shift gears smoothly and stop safely while receiving loads.
Tokai Carbon produces friction materials in small batches of many varieties, including Toyoca FC for ship clutches.
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 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.
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.
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.
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.
Cloth pre-woven with fibers is impregnated with resin and baked hard. The resultant material is suitable for friction materials used in oil.
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.
