80A / 75D DUAL DUROMETER URETHANE TUBE - ORANGE OUTER CORE 2-3/4" ID X 4-3/8" BEARING OD X 6" OD X 1-3/4" LONG ITEM MAY HAVE SLIGHT BLEMISHES OR SURFACE IMPERFECTIONS A low-cost alternative for wheels, casters, rollers, sheaves, etc. Two grades urethane permanently bonded together, resulting in a hard anti-friction hub with softer outer tire. 75 D durometer hub can serve as a bearing in some applications. ID’s, OD’s, lengths and profiles can be machined to fit your application. Use to make low cost OEM components for your manufactured products. Nominal OD’s +/- 2% I.D.’s are slightly oversized to provide running clearance Custom shapes & sizes are available! See our website for additional items www.polytechinnovations.com ALL DIMENSIONS ARE NOMINAL. TOLERANCE ON ID, OD, AND THICKNESS IS +/- 2% AND LENGTH AND WIDTH IS +/- 1/4".
