* Operate the cylinder with in the allowable kinetic energy.

Note 1) Intermediate strokes not listed above are produced upon receipt of order. Manufacture of intermediate strokes in 1 mm intervals is possible. (Spacers are not used.) Note 2) Applicable strokes should be confirmed according to the usage. For details, refer to “Air Cylinders Model Selection” on front matter pages of the Best Pneumatics No. 2 or the WEB catalog. In addition, the products that exceed the standard stroke might not be able to fulfill the specifications due to the deflection etc.
