A vibration damping base for an engine and shaft. A pair of spaced shaft bearings are coaxially supported in a pair of spaced, parallel plates. Upper and lower support arms are connected to the plates and extend transversely of the bearing axis. The support arms are tubes of rectangular cross-section which are engaged adjacent their ends by facing, U-shaped brackets having elastomeric linings. The support arms are connected to flanges of longitudinal beams forming part of the base and made of two channels. One support arm is welded at each end to a flange of a first channel which has surface engagement with a flange of a second channel.
