How does friction change as a function of runtime?

The igus® lab has determined that the friction of iglidur® plain bearings exhibits very little change as a function of runtime. Rolled metallic plain bearings were tested for comparison. Since these only have a thin gliding layer on the surface, friction and wear increase as soon as this layer is worn.

Wear comparison
Test results Coefficient of friction (rotating); v=0.1 m/s; p=1; t=2h
Shaft: zinc die-casting
Orange: iglidur® P210
Grey: rolled metallic bearing with PTFE insert
Left: new plain bearings
Right: plain bearings from wear test
