Need to design a Pulley drive System? We've made it easy! Center Distance Designer Program •  Allows the design of a pulley drive system using our belt and pulley database. •  Allows locating catalog pages featuring the belts and pulleys used. •  Calculates minimum and actual center distances, speed ratios and teeth in mesh (T.I.M.) for both pulleys. •  Compiles two convenient tables: a)  A table of center distances vs. number of belt teeth.  It displays five sizes larger and five sizes smaller stock belts than the actual belt length. b)  A table of all pulley pairs within specified speed ratio range. •  Exportable .DXF and .DWG drawings.
