Surface Speed Chemical resistance

The peripheral speed is always significant in plain bearings. bearings for rotating, pivoting, and linear movements. These iglidur plain bearings can come into contact with many u Chemical table, page 1170

The absolute speed is not crucial, but the relative speed surface speeds are limit values assuming minimal pressure chemicals during their use. This contact can lead to
