Since the invention of rotating machinery, gears are known for their force multiplying properties. But did you know…     Greek mathematician Archimedes (287 B.C.—212 B.C.) designed a number of machines that utilized gears? Many early gears in industrial applications were made of wood with cylindrical pegs for cogs and lubricated with animal fat? You can find a more cost-effective solution for your gear requirements by turning to powder metal (PM)?     Let me give you some ideas (click here).     www.symmco.com   ©Symmco Inc. 2013
