Stick slip a cause for malfunction of plain bearings. again, it is observed that these noises do be eliminated with rough shafts. Thus for have a great potential for stick slip – slow resonance of the housing – attention must optimal roughness of the shafts. Graph 11: Coeffi cients of friction of the iglidur® plain bearings at the recommended shaft surface roughness and low load, p = 0,75 MPa Depending on whether an application is starting from a stationary position or the movement is in progress and needs to be maintained, a choice is made between static friction coeffi cient and the dynamic friction coeffi cient. Coeffi cients of Friction and Surfaces At study here is the relationship between coeffi cients of friction and surface roughness of shaft materials. It is clearly shown that the amount of friction is composed of different factors. If the shaft is too rough, abrasion levels play an
