Calculation

Example) JMDBB32-100 (Basic, ø32 [32‑mm diameter], 100 mm stroke)

  • Basic weight: 0.21 (Basic, ø32 [32-mm diameter])
  • Additional weight: 0.11 / 50 stroke
  • Cylinder stroke: 100 stroke

0.21 + 0.11 × 100/50 = 0.43 kg

Example) Find the upper limit of the rod-end load when an air cylinder of ø50 (50-mm diameter) is operated at 300 mm/s.
From a point indicating 300 mm/s on the horizontal axis, extend a line upward and find a point where it intersects with a line for the 50-mm bore size. Extend a line from the intersection to the left and find a load mass of 40 kg.

Precautions

  • *1Allowable lateral load: The lateral load that can be applied to the piston rod end is limited. If a cylinder is used with a lateral load over the limit, it may cause air leakage due to abnormal friction of seals, galling of cylinder tubes and pistons, or abnormal friction of the bearing part. The lateral load applied to the piston rod must be within the allowable range indicated in the manufacturer's catalog. If the load exceeds the limit, install a guide or change the bore size to suit the load in order to bring the load within the allowable range.
  • *2Connection with a workpiece: When a workpiece is mounted on the piston rod end, connect them aligning the center of the piston rod and the workpiece. If they are off-center, a lateral load is generated and the phenomena mentioned in *1 may occur. In order not to apply an off-center load, use of a floating joint is recommended.
  • *3Simultaneous use of multiple cylinders: It is difficult to control the speed of pneumatic cylinders. The following conditions cause speed change: change in supply pressure, load, temperature and lubrication, performance difference of each cylinder, deterioration of each part over time, etc. A speed controller can be used to control the speed of multiple cylinders simultaneously for a short period of time; but depending on conditions, it may not work as desired. If multiple cylinders cannot operate simultaneously, unreasonable force is applied to the piston rod because cylinder positions may not be the same. This may cause abnormal friction of seals and bearings, and galling of cylinder tubes and pistons, etc. Do not use an application to operate several cylinders simultaneously by adjusting the cylinder speed. If operating several cylinders simultaneously is inevitable, use a highly rigid guide for the load so that the cylinder is not damaged even when the cylinder output differs slightly.
  • *4 Depending on the system configuration selected, the specified speed may not be satisfied.
  • *5Before using, please refer to the "Safety Precautions," the "Common Precautions," and the "Auto Switch Precautions."
  • *6See the manufacturer's catalog for information other than that above.
