Composite Material Products

Designed for light weight, compact size, low friction, low wear and use for special environments!
Molding and machining various materials with advanced technologies for proposing the optimum products.

The NTN Group uses a wide range of materials such as resins, sintered metals and magnetic materials, as well as advanced technologies such as fluid hydrodynamic technology for the development of units and module products consisting of sliding bearings, and electrical and machine parts, and markets them as composite material products.

In addition to using materials such as resins sintered metals and magnetic and fluid hydrodynamic technology by itself tribology and precision machining technologies are applied for their integration and composite use to create materials with new characteristics that meet market needs.

Composite material products can be custom-made to order, so feel free to contact us.
