MI 00 603 ................... download or print pdf
DESCRIPTION:
Developed upon the base product MI 00 602 short fiber technology has been used to produce a low wearing material suited to constant operation.
Having relatively high graphite content, not only the difference between dynamic an static friction coefficient is reduce, but also its operational noise level.
SOME TYPICAL APPLICATIONS:
Low frictional torque limiting and tension brake applications.
ADHESIVES:
The use of any well known thermosetting adhesive is recommended.
RUBBING SURFACES:
Good quality, fine grained pearlitic cast iron with Brinell hardness of 150-200 is recommended.
