The following general formula should be used for determining the actual applied load: L = Actual applied load kg (lbs) N = Shaft speed (rpm) D = Pitch diameter mm (inches) of pulley, etc. F = Load factor, 1.0 for chain or gear drive, 1.5 for timing belts, 2.5 for all V belts, 3.5 for flat belts. LF = 2.1 for reciprocating compressors and other severe shock drives and 1.8 for large inertia type drives (i.e. Crushers, chippers, planers, etc.) Compound Drives and Power Engaged Power Take-Off applications must have written factory review.
