∗ The manufacturing of intermediate strokes is possible. (Spacers are not used.)
∗
Applicable strokes should be confirmed according to the usage. For details, refer to the Air Cylinders
Model Selection in the Web Catalog or Best Pneumatics Catalog. In addition, products that exceed
the stroke range q might not be able to fulfill the specifications due to deflection, etc.
∗ Please consult with SMC for details on manufacturability and for part numbers when exceeding
the stroke range w.
∗ When using a rod boot, a stroke range of up to 1000 mm is available. Please consult with SMC
when exceeding a 1000 mm stroke.
