Applications requiring the self-lubrication, wear resistance and quiet operation of nylon gears, but which are too demanding for solid plastic, might benefit from the use of plastic gears with steel cores. One company offering a solution in this area is[ Duragear, Inc.], which specializes in the manufacture of plastics suitable for machining. Their NylaSteel™ product is designed for manufacturers of gears, rollers, pulleys, wheels and sprockets. The composite stock shapes are available in standard configurations or with custom-designed steel cores. The steel core allows NylaSteel™ gears to be attached to a steel shaft the same way as steel gears are, including press-fit, bolt cycle or keyway. NylaSteel™ billets come in diameters up to 10.5" and lengths up to 24", with steel core diameters from 1.5" to 4.5". The billets can be saw-cut and machined on a gear hobber. [Duragear] can also manufacture custom-designed hubs, including those that extend beyond the face width. NylaSteel™ blanks and billets are available with several nylon varieties and either cold-rolled 1117 steel or stainless cores.
