Class Information
Number: 384/1
Name: Bearings > Vibratory (e.g., piezoelectric or kinetic bearing
Description: Subject matter wherein vibration e.g., brought about by a piezoelectric effect, results in reduced friction, either through creation of a fluid film or otherwise; or where motion in one direction is used to reduce the friction coefficient in another direction.
