Characteristics and applications
Mechanical applications. Reinforced with finer fabric than Etronax MF. Can be used, in particular, for mechanical applications where fine tolerances and smooth surface finish are required. Examples of applications are ball-bearing cages for spindle bearings and guide rings for hydraulic cylinders.
