Note 1) Be aware that when the stroke adjustment range is increased with the adjustment bolt,
the air cushion capacity decreases. Also, when exceeding the air cushion stroke ranges
on page 1191, the piston speed should be 100 to 200 mm/s.
Note 2) The piston speed is 100 to 1000 mm/s for centralized piping.
Note 3) Use at a speed within the absorption capacity range. Refer to page 1191.
Note 4) Due to the construction of this product, it may have more fluctuation in operating speed
compared to a rod type air cylinder. For applications that require constant speed, select
the equipment corresponding to the required level.
