Pivot bearing and transoms linings made out of graphitamide for freight wagons two-axle bogies UIC Y25

Azbestosfree graphitamide – graphite composite in synthetic resine matrix reinforced with fibres has the ability to adjust its shape, absorb vibrations and impact energy, stress and abrasive contaminants. It is resistant to water, oil, petrol, alkalis and acids. The exceptionally high resistance to wear of graphitamide is achieved by reinforcement of fibres lubricated by graphite, which create sliding structure protecting the matrix resin from abrasion.

The use of graphitamide pivot linings and transoms is allowed in temperature from -40 C to +180 C.
