  1. *1: Consult with SMC regarding intermediate strokes. (Spacers are not used.)
  2. *2: The applicable stroke should be confirmed according to the usage. See the SMC catalog for details. In addition, products that exceed stroke range 1 may not be able to meet the specifications due to deflection, etc.
  3. *3: Contact SMC for information regarding manufacturability and part numbers when exceeding stroke range 2.
  4. *4: The stroke range when with the rod boot is up to 1,000 mm. Contact SMC when exceeding 1,000 mm.
