The AirTAC Airtac SAI100 Standard Air Cylinder SAI100X255S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 255mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI100X255-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N of push force at 0.7 MPa, this 100 mm bore unit is built to handle substantial loads over its 255 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean profile that is dimensionally interchangeable with other ISO 15552 cylinders.
Equipped with a piston magnet (-S), this model directly supports CMSE and DMSE sensor switches via the integrated grooves on both sides of the barrel. It features a standard carbon steel piston rod for excellent tensile strength and uses adjustable air cushions at both ends to decelerate heavy moving masses smoothly. For environments exceeding standard temperature limits, Viton (H) seals can be specified to maintain thermal stability.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the necessary 5497 N push force at 0.7 MPa to actuate medium-tonnage stamping and forming presses reliably.
Moves heavy loaded pallets along material handling lines, utilizing the 255 mm stroke to push loads cleanly off the main conveyor belt.
Applies consistent downward pressure for assembly operations, using adjustable air cushions to prevent end-of-stroke impact damage.
Selecting this 100 mm bore is ideal when a 80 mm bore falls short—yielding 3518 N at 0.5 MPa compared to the 80 mm's 2513 N. Conversely, if your application only requires around 1400 N of push force, stepping down to a 63 mm bore reduces air consumption and physical footprint. Because this model features a 255 mm stroke, the unsupported rod length during extension requires careful consideration to prevent rod-bearing bending under side loads.
To manage side-load stress, implement an external guide rail or choose a guided cylinder variant to prevent premature seal wear. Note that the adjustable air cushion only decelerates the piston at stroke end; it does not lock the load. If the system loses air pressure, the rod will drift, so an external pilot-operated check valve or the SAIL locking variant is required for static holding. This cylinder uses a G1/2 PT port, accepts standard ISO 15552 mounting accessories like the FA flange or TC trunnion, and requires the -S magnet for proximity sensing.
Quick checklist
At 0.7 MPa operating pressure, this 100 mm bore cylinder generates a push force of 5497 N and a pull force of 3681 N. At 0.5 MPa, the push force is 3927 N.
Yes, the SAI100X255-S is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders with matching 100 mm bore and 255 mm stroke specifications.
