 Antifriction Carbon Materials


Carbon graphite materials
Are used to manufacture the parts of friction blocks for machines and hardware operating without lubricant and in the conditions of steady or smoothly changing load, for instance, thickening rings for the shafts of turbine expansion engines (working medium is nitrogen), bearing sliding shells and face thickening rings of centrifugal pumps (medium liquid gases, petroleum, kerosene, diesel fuel, black oil), thickening rings for hydraulic pumps (medium oil), etc.

For the parts made of the material -1500 it is recommended to use steels of all grades and hardnesses and chrome dressing as the countershank material; permissible specific pressure is 10-15 kgc/cm2; permissible speed is 30 m/s.
For the parts made of the material -600 it is recommended to use the same countershank material as for the parts made of -1500 material, permissible specific pressure is 10-12 kgc/cm2; permissible speed is 20 m/s. Permissible working temperature upon exploitation of products made of -1500 and -600 materials in the oxidizing medium comes to 400-450 C, in the reducing and neutral media is 2300-2500 C.
Amount of wear at permissible specific pressures and speeds in the conditions of dry friction in the air at the indoor temperature for 100 hours of operation is not more than 50 mkm
