The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 30mm stroke, G1/4 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 SAI40X30 is a double-acting ISO 15552 profile cylinder engineered for compact actuation, delivering a robust 628 N of push force at 0.5 MPa. Its 30 mm stroke is tailored for short-travel clamping, ejection, and indexing tasks where space is restricted but reliable power is required.
This extruded aluminum barrel design incorporates dual sensor grooves compatible with DMSE switches when a magnet is specified. Furthermore, operators can optimize environmental resilience by selecting NBR seals for general pneumatic duties or upgrading to Viton for high-temperature zones.

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 securely holding lightweight machined components during secondary milling or drilling operations.
Provides rapid, targeted push-offs for diverting small cartons or products between adjacent conveyor lines.
Drives compact sorting flaps and indexing mechanisms where a brief 30 mm travel distance is required.
If your layout demands even less footprint and can operate on 402 N of push force at 0.5 MPa, the 32 mm bore variant is a logical step down. Conversely, stepping up to the 50 mm bore yields 982 N for heavier resistance. Because this 30 mm stroke is very short, side-load stress on the rod bearing is naturally minimized.
This unit utilizes a PT tapered G1/4 port and a carbon steel rod as standard. It serves as a dimensionally interchangeable drop-in replacement for any standard ISO 15552 cylinder. Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load if air pressure drops, so deploy an external rod lock for fail-safe positioning.
Quick checklist
At a 0.5 MPa operating pressure, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. Increasing the supply to 0.7 MPa yields 879 N of push force.
Yes, the SAI40X30 is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with equivalent ISO 15552 cylinders from other manufacturers.
