An integrated bearing system with journal and thrust bearings is incorporated in a single unit centrally pinned to the bearing housing and having integral thrust surface and journal surface lubrication grooves in combination with turbine and compressor wheel thrust surfaces. The bearing employs a first aperture substantially equidistant from the ends to engage the locating pin to prevent rotation of the bearing within the bearing case bore, while allowing the bearing to be free to symmetrically wobble within the bearing case bore.

A portable blower-vacuum unit has an impeller for drawing air axially through a housing air inlet, and for discharging the air centrifugally through a tangential housing air outlet. In a blower mode, a perforate cover plate prevents ingestion of solid material by the impeller. In a vacuum mode, a vacuum conduit connects to the housing in lieu of the cover plate, and a vacuum bag attaches to the air outlet. A mulching blade rotates with the impeller to chop any solid material passing through the housing when the unit is operated in the vacuum mode.

A chain saw including an improved suspension system characterized by a U-shaped hand grip means extending transversely across a longitudinal median plane of a guide bar means, with the U-shaped hand grip means being contiguous with a longitudinally extending rear handle and serving to house, at least in part, a portion of the chain saw vibration isolation system. Generally longitudinally aligned vibration isolation units are constrained by abutment means and axially oppositely directed mounted shaft means to impede axially oppositely directed movements of a vibration generating assembly relative to the chain saw suspension system.
