ABSTRACT:
A roller for operation in a gaseous environment, perhaps containing solid particles; the roller requiring cooling. A central axial cylindrical aperture surrounding a shaft upon which the roller rotates has a continuous helical groove that extends the full length of the aperture. Upon rapid rotation gas traverses the groove, cooling the roller and removing any solid particles otherwise trapped between the aperture and the shaft.
