Friction material (facing)

For many years since our founding, we have been highly praised for our basic performance, such as transmitting power and staying still, and have held a 90% share of the domestic market for centrifugal clutches for small engines.
By applying this proven technology, developing materials that are compatible with the operating atmosphere and environmental laws, and using optimal production methods depending on the number of production volumes, our products have been adopted in a wide range of applications.

Friction material (facing)

Applications and physical property data of main friction materials (Test method: JIS-D 4411 / JIS-K 6911 / JIS-D 4413)
The following is an example, and there are 30 types of results.
Depending on the application, we can handle “friction material selection, blend design ➡ prototype ➡ evaluation ➡ mass production.”
