350V series double-acting cylinders : 350 bar hydraulic cylinders - Quiri - 4

Cylinder selection based on buckling stress

Maximum force : Take account of extreme operating conditions: overpressure, dynamic forces, fastener reactions, etc. Avoid end-of-stroke shocks (damping for high speed >0.15 m/s)

Port : Select them according to the generator flow rate, taking into account the ratio of extend and retract cross-sections.

Buckling : Determine the cylinder using the table below, which give the maximum length compatible with buckling according to force, operating pressure, bore and rod diameters.
• To obtain the maximum stroke Cmax resistant to buckling, multiply the buckling length L in Table I by the correction coefficient K in Table II, depending on the type of fastener.

Cmax.=KL

• Choose preferably fasteners that are more resistant to buckling, leading to smaller cylinders and therefore lower costs.

Determining the weight of a cylinder : Weight in kg = P + (Z x stroke in mm)

Numerical example :

Bore Ø 125 VN Type : P=63,3
Per mm of stroke : Z=0,0923
Stroke in mm : 800
Weight =63,3+(0,0923*800) = 137,14 kg
