The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X50CA is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 50mm 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 SAI40X50 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 50mm stroke. It delivers a push force of 628 N at 0.5 MPa, making it well-suited for compact actuation tasks requiring moderate thrust. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates easily into tight machinery layouts.
This unit is configured with a standard carbon steel piston rod and PT tapered G1/4 ports. The barrel includes integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if position feedback is later required. Adjustable air cushions at both ends ensure smooth piston deceleration, protecting components from end-of-stroke impact.

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 rapid 50mm stroke actuation to push or deflect lightweight packages on a high-speed distribution conveyor line.
Generates 628 N of clamping force at 0.5 MPa to secure small to medium workpieces during light machining or assembly operations.
Powers small access gates or machine guards, utilizing the adjustable end cushions to prevent slamming and mechanical wear.
Choose this 40mm bore when an adjacent 32mm bore (402 N push at 0.5 MPa) lacks sufficient thrust, but a 50mm bore (982 N) would be physically oversized. The 50mm stroke offers precise short-travel movement. For installations needing position holding without continuous air pressure, select the SAIL locking variant or an external rod lock, as standard air cushions only decelerate the piston and cannot hold a load.
To match this exact configuration for an ISO 15552 interchange, specify a 40mm bore, 50mm stroke, G1/4 PT port, CA clevis mounting accessory, and no magnet (-S). Always verify that the chosen CA clevis accommodates the pin size required by your mechanical linkage.
Quick checklist
The SAI40X50 cylinder provides a push force of 628 N and a pull force of 528 N when operated at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes, this profile cylinder is dimensionally interchangeable per ISO 15552. To match this exact configuration, ensure your setup uses a 40mm bore, 50mm stroke, G1/4 PT port, and CA clevis mounting.
