The AirTAC Airtac SAI100 Standard Air Cylinder SAI100BX45S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 45mm 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 SAI100X45-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning tasks. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for short-stroke clamping and high-thrust ejection operations. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that resists mechanical snagging in tight machine cells.
Built specifically for harsh environments, this unit incorporates a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. The integrated magnet (-S) allows seamless operation with CMSE and DMSE series reed switches, mounted directly into the dual sensor grooves on the barrel. Standard adjustable air cushions at both ends manage piston deceleration effectively within its 30-800 mm/s operating speed range.

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 3927 N force required to seat bearings, pins, and bushings in automated assembly presses without requiring a full hydraulic system.
Acts as a heavy-duty pusher at packaging line intersections, using its short 45 mm stroke to rapidly kick heavy cartons onto downstream transfer belts.
Delivers reliable high-impact ejection force to free dense plastic parts from injection molds, utilizing the robust SUS304 rod to withstand repetitive impact stress.
Choose this 100 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) lacks sufficient thrust for heavy lifting or pressing. If your application requires even greater force, stepping up to a 125 mm bore yields 6136 N. Because the stroke is only 45 mm, side-load stress on the rod bearing is minimal, meaning external guide rails are usually unnecessary unless handling severe eccentric loads.
As a standard double-acting actuator, this cylinder relies on continuous air pressure to maintain its position; it will drift if compressed air is lost or the control valve is centered. For vertical loads that must be held securely during an air failure or emergency stop, specify the SAIL variant with an air-released locking mechanism or utilize an external rod lock. This model uses a PT tapered port thread and is dimensionally interchangeable with any standard ISO 15552 mounting interface.
Quick checklist
At a standard operating pressure of 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X45-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions and port locations are standardized. It serves as a direct dimensional drop-in replacement for other ISO 15552 cylinders of the same bore size, utilizing standard FA, FB, and TC mounting accessories.
