How to Select Cylinder Bore Diameter Based on Load Requirements

How to choose cylinder bore? Determine the required load, then calculate the appropriate bore diameter.

Selection Parameters:
 1. Compressed air supply pressure
 2. Direction of force (thrust or pull)

Calculation Formulas:
  Thrust Force Fo = 0.25πD²P
  Pull Force Fo = 0.25π(D² - d²)P

Variables:
  D = Piston diameter (cm)
  d = Piston rod diameter (cm)
  P = Working pressure (kgf/cm²)
  Fo = Theoretical output force (kgf)

Notes:
1. Valid for cylinder speeds of 50–500 mm/s.
2. For vertical upward mounting, usable thrust ≈ 50% of theoretical value.
3. For horizontal mounting, actual force ≈ theoretical force (accounting for inertia).
