Caution When operating a cylinder for the first time, make sure to release the air at low pressure. When the air release is complete, operate the cylinder at reduced pressure, gradually increasing it to the normal operating pressure. owever, the piston speed at this time should be adjusted to the minimum speed.

When mounted with one side attached and one side unattached (basic type and flange type) and operating at high speed, bending moment acts on the cylinder due to oscillation at the stroke end, which may cause cylinder damage. In this case, install brackets to suppress the oscillation of the cylinder body, or reduce the piston speed enough so that the cylinder body does not oscillate at the stroke end.

Series CN Model Selection 1 Cylinder Cushion Selection Procedure Find the inertial energy E1 for the load at the cushion seal contact point. Caution Use a cylinder cushion within the maximum absorbed energy range. When used outside the allowable range, it may cause damage to cylinders and peripheral devices. Find the external force F applied in the axial direction of the cylinder at the cushion seal contact point. Convert the external force calculated in step above into energy E using the external force energy conversion chart. From the maximum absorbed energy-pressure chart, find the maximum absorbed energy E for the corresponding cylinder. YES YES YES Confirm E1 + E E YES Lower the set pressure Use larger bore size NO NO NO Reduce inertial load NO vailable for use Install a shock absorber Calculation Example <Design conditions> Cylinder: CN Set pressure P1: MPa Load weight M: kg Piston speed V:.3 m/s (at the cushion seal contact point) Load transfer direction: Downward θ: 3 (External force applied to the cylinder is gravity only). Operating direction: Out Gravitational acceleration g:. m/s <Calculation> 1. Load inertial energy E1 at the cushion seal contact point E1 = MV / = x.3 / =.J. External force F applied in axial direction of the cylinder at the cushion seal contact point F = Mg sin θ = x. x sin 3 = N 3-1 Mg sin θ 3 θ Mg 3. Convert the external force calculated in step into energy E. In the "External force and energy conversion chart" on page 3-, draw a vertical line from the value of F (= N). The point where this line intersects with the diagonal line (.J) is the energy caused by external force. E =.J. Find the maximum absorbed energy E for a cylinder. In the "Maximum absorbed energy and pressure chart" on page 3-, draw a vertical line from the set pressure MPa. The point where this line intersects with the line for ø (3.J) is the maximum absorbed energy. E = 3.J. Confirm that E1 + E E E1 + E =. +. =.J Since E = 3.J, E1 + E E Therefore, the cylinder cushion is available for use.
