Belt Length Calculator_Online Calculation Tool

Belt length calculator

Belt length calculation formula:

\(lb = ((d f + d m) 1.5708 ) + (2 l fm)\)

Lb = belt length

Df = large pulley diameter

Dm = small pulley diameter

Lfm = center distance between the center of the large pulley and the small pulley

Belt speed calculation formula:

\(v = π d m n m / 12\)

v = belt speed (ft/min)

Nm = motor speed (rpm)
