Characteristics and applications
Mechanical applications. Impact-resistant, noise-reducing and wear-resistant construction material. Well suited as a low-friction material. High wear resistance in aggressive and dustfilled environments. Can be lubricated with water, oil or grease. Resistant to weather and salt water. Examples of applications are bearings bushes, rudder bearings and guide rings for hydraulic cylinders.
