Belt Length Calculator

L = 2C + π(D₁+D₂)/2 + (D₁-D₂)²/(4C)

C = (L - π(D₁+D₂)/2)/2 + √((L-π(D₁+D₂)/2)²/4 - (D₁-D₂)²/4)

L = 2C + π(D₁+D₂)/2 (Approximate)

C = (L - π(D₁+D₂)/2)/2 (Approximate)

L = belt length, C = center distance, D₁ = large pulley diameter, D₂ = small pulley diameter, π = pi (3.14159)

Calculation Method:

Large Pulley Diameter D₁ (mm):

Small Pulley Diameter D₂ (mm):

Center Distance C (mm):
