Self Lubricating Oilless Carbon Solid Graphite Impregnated Bushings
Metal or Resin Impregnated Graphite Parts are widely used in
equipments of modern industry, such as seal rings for centrifugal
pumps reacting kettle for chemical engineering, hydraulic
generators and rotate baking furnaces; piston rings and bushings
for compressors oxygen machines and bellows, bearings for screen
motors and other types of instruments; slides for motors, subways
and mine brushes of electrical machinery and slides for
trolleybuses, etc.
