Abstract
A rotary viscous vibration damper or absorber has a hub part which can be fastened to a crankshaft of an engine, in particular of an internal combustion engine, and a vibration damper ring which is mounted such that it can be rotated relative to the hub part. A shear gap which is filled with a silicone oil is formed between the hub part and the vibration damper ring, in which shear gap flange bushings for guiding the vibration damper ring are mounted. The flange bushings are composed of a liquid crystal polymer.
