The AirTAC SAI40 Standard Air Cylinder SAI40AX140 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 140mm 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 SAI40X140 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 140mm stroke. It delivers 628N of push force at 0.5 MPa, making it well-suited for mid-range actuation tasks. The extruded aluminum barrel eliminates exposed tie rods, providing a clean exterior that resists mechanical interference.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or mildly chemically washed environments. It uses PT tapered port threads, and because no magnet is specified, it operates without internal sensor tracks. The adjustable air cushions at both ends ensure smooth deceleration across its 30-800 mm/s 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 reliable 628N push force at 0.5 MPa for securing medium-sized workpieces during machining or light assembly operations.
The 140mm stroke and 30-800 mm/s speed range allow swift and precise actuation of routing gates on automated packaging lines.
Ideal for elevating lightweight pallets or totes, utilizing the SUS420J2 stainless steel rod to withstand mildly humid warehouse conditions.
Select this 40mm bore when a 32mm bore (402N push at 0.5 MPa) is insufficient, but a 50mm bore (982N push at 0.5 MPa) would be physically oversized. The 140mm stroke offers ample travel for clamping or lifting tasks. For applications requiring position holding without continuous air pressure, the standard SAI cannot sustain a load; consider the SAIL variant with an air-released lock or an external pilot-operated check valve.
As a true ISO 15552 cylinder, this model is dimensionally interchangeable with other ISO 15552 profile cylinders. To replicate this exact setup, match the 40mm bore, 140mm stroke, PT G1/4 port, and pair it with an FA or FB flange mounting accessory. Add the -S suffix if you later require sensor switches.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI40X140 provides 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
Yes. The SAI40X140 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are standardized for direct interchangeability with other ISO 15552 profile cylinders, though it is not identical to any specific brand's proprietary part.
