  • the invention relates to machine parts that are provided with a friction face.
  • the invention relates to a method for providing high static friction between two machine parts that are clamped together or otherwise mutually pressed against each other by means of a substantial force normal to the frictiously contacting mating faces to avoid relative shear movement.
  • Static friction coefficient between smooth steel surfaces is in the range of 0,07 to 0,2.
