Abstract
A viscous torsional vibration damper has an annular damper housing defining a damper chamber; an inertia ring in the damper chamber; a bearing device supporting the inertia ring with one or more bearing elements. At least one bearing element is a ring not circumferentially closed in a mounted state. A shear gap between the inertia ring and the damper housing is filled with a viscous fluid. The at least one bearing element that is not circumferentially closed is cut to length from a strip. In order to produce the bearing element, a strip is provided, on which one or more axial bearing sections and one or more radial bearing sections and preferably one or more webs are formed. Then, the bearing element is cut to length from the strip and the bearing element is inserted into an open damper housing and laid on a bearing seat.
