The AirTAC SAI40 Standard Air Cylinder SAI40AX80S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 80mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI40X80-S is a double-acting ISO 15552 profile cylinder engineered for direct interchangeability with standard pneumatic systems. Delivering a push force of 879 N at 0.7 MPa, this 40 mm bore unit is paired with an 80 mm stroke to deliver precise linear motion in confined machinery layouts.
This configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance over standard carbon steel. The integrated magnet (-S) allows seamless operation with CMSE or DMSE reed switches fitted directly into the dual sensor grooves on the extruded aluminum barrel.

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.
Ideal for securing workpieces during CNC machining, using the 879 N force to hold components firmly against fixtures.
Provides rapid actuation for diverting small to medium packages on automated material handling lines.
Actuates safety gates and machine guarding doors where reliable, short-throw linear movement is required.
Select this 40 mm bore when an application requires stepping up from a 32 mm bore (which provides 563 N at 0.7 MPa) to handle heavier actuation without the bulk of a 50 mm cylinder. The 80 mm stroke is optimal for short-cycle clamping and lifting tasks. If your process demands position holding upon air loss, a standard SAI will drift; utilize the SAIL variant for an integrated air-released lock instead.
For replacement planning, verify the 40 mm bore, 80 mm stroke, PT tapered G1/4 port, and required mounting accessory (such as an FA flange or LB foot). The -S suffix confirms the magnet is present for sensor tracking.
Quick checklist
At an operating pressure of 0.7 MPa, this 40 mm bore cylinder provides a push force of 879 N and a pull force of 528 N.
Yes, the SAI40X80-S is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders with matching 40 mm bore and 80 mm stroke specifications.
