A bearing system comprising: (A) a stationary support housing having a longitudinal opening therethrough for positioning a rotatable shaft substantially aligned therein; (B) an essentially non-rotatable bearing housing positioned between said shaft and said support housing comprising at least one pair of bearing means, each bearing means having a bearing surface for rotatably supporting said shaft, and a spacer portion between said pair of bearing means, said spacer portion not supporting said shaft; (C) viscous damping means comprising a generally uniform annular space between said support housing and said bearing housing along at least a portion of theiuraxial length, said axial length portion being greater than the axial length of said bearing surfaces, said annular space being filled with a viscous material through said axial length portion; and (D) a plurality of spaced elastic supports in contact with said bearing housing and said support housing.
