The band saw self cooling roller guide is defined by a main cylindrical roller body having a front portion of reduced diameter forming a collar for mounting coaxially around a shaft, and a flange extending from the rear portion thereof forming a shoulder. The thin rear edge of the band saw blade or ribbon abuts the flange which aids in aligning the blade, and the flat surface of the blade rests upon a plurality of grooves formed around the peripheral surface of the main roller body. A plurality of apertures such as louvered holes are formed in the face of the body and extend through the flange to funnel air their the rotating roller body cooling the roller, aligning the blade, and extending the wear thereof.
A bandsaw blade roller guide comprising a body member having a front face and a rear face and mountable by suitable bearing means for rotation about an axis passing through said faces, said body member having an outer peripheral surface parallel to said axis for rollingly engaging a side flat face of a bandsaw blade and a flange extending outwardly from said flat face adjacent an edge thereof, said flange having a front face surface disposed perpendicular to said peripheral surface for engaging the rear edge of said bandsaw blade, said body member having a plurality of passages extending there through with inlets thereto in selected one of said front and rear faces and outlets therefrom in the other one of said faces and means adjacent said inlets to cause air to flow through said passages during rotation of the roller.
