Graphite transmission Discs


Graphite is a moulded friction material with a high percentage of carbonaceous composites which gives the material its extremely high energy dissipation capacity. That is why it is supplied as original equipment in various applications such as axles, wet brakes & power shift transmissions. The material is 30% porous & is only used for wet application. The following are properties that are associated with this type of material:


> Outstanding thermal stability in high energy applications
> Stable coefficient of friction
> Good wear resistance
