Advancing Chain technology231Roller Drive Chain SelectionTechnical Information29Required Information for Drive Selection :1. Type of input power (electric motor, internal combustionengine, etc.).2. Type of equipment to be Horsepower (HP) to be Full load speed of the fastest running shaft (RPM).5. Desired speed of the slow-running : If thespeeds are variable, determine the horsepower to betransmitted at each Diameters of the driver and driven Center distance of the : If this distance is adjustable, determine theamount of Position of Drive and space limitations (if any).9. Conditions of the Drive . Drives with more than twosprockets, idlers, or unusual conditions such as severelyabrasive or corrosive environments, severely high or lowtemperatures, widely fluctuating loads, frequent startsand stops, etc.

C = Center Distance (inches)/Chain Pitch (inches) The required chain length in feet (L) may be obtained from: L = (Chain Length in Pitches x Chain Pitch in Inches)/12 Slow Speed Selection If the linear chain speed is less than 160 ft./min., then a chain that is one size smaller than selected with the above method may be used.
