Abstract:
1. A seal for preventing contaminants from infiltrating and fouling a conveyor idler roll, the seal comprising: a disc of resilient material attachable to an end cap of the idler roll, the disc having a top face, a bottom face, and a circular aperture through the center thereof, the aperture being at least large enough to permit the disc to freely rotate about a fixed axle of the idler roll when the disc is attached to the end cap of the idler roll, the disc further having a raised rim located around the periphery of the bottom face of the disc to provide a surface for attaching the disc to the end cap of the idler roll; and at least one ring of porous material attached to the bottom face of the disc circumferentially to the aperture to filter out contaminants by providing the seal with a snug fit against the end cap of the idler roll when the seal is attached thereto; wherein the disc and the attached porous ring are divided along a part line of the disc to form two substantially semicircular half-pieces comprising a first half-piece having a diametral edge and a second half-piece having a diametral edge opposing the diametral edge of the first half-piece.
