Airtac SAID40 Double Rod Cylinder SAID40AX195S
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40AX195S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 195mm 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.

About the Airtac SAID40 Double Rod Cylinder SAID40AX195S
The AirTAC SAID40X195-S is a double-acting, double-rod ISO 15552 profile cylinder. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 739 N of force in either direction at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and the -S magnet enables tracking via AirTAC CMSE reed or DMSE solid-state switches.
This variant uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. The twin-rod architecture is ideal for mounting a primary workpiece on one end and a cam or position flag on the opposite rear rod, providing dual-side guidance and superior anti-rotation stability compared to a single-rod SAI.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX195S Is Used
Symmetric Force Transfer
Delivers identical 739 N push and pull forces at 0.7 MPa, ensuring perfectly balanced speed and power for transfer arms moving loads in both directions.
Anti-Rotation Slides
The twin-rod design naturally resists torsional twist, keeping guided slides and pick-and-place heads perfectly aligned without external guide rails.
Rear-Rod Sensing
The -S magnet pairs with CMSE and DMSE switches, while the rear rod end can independently drive a secondary mechanism or hard flag for dual-station actuation.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX195S the Right Cylinder?
Choose this 40 mm bore when an application demands symmetric push/pull forces (739 N both ways at 0.7 MPa) and anti-rotation guidance. If you need less force, the 32 mm bore offers 483 N; if your load requires more, the 50 mm bore provides 1154 N. The PT (tapered) port thread and G1/4 port size are fixed by the 40 mm bore. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (FB, CA, CB, and CR are omitted on this double-rod variant).
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders for drop-in replacement. At 195 mm stroke, side-load bending is moderate, but always ensure the rod bearing is not overloaded. Note that the adjustable air cushions only decelerate the piston near stroke end; this cylinder does not hold position if air pressure is lost. For load-holding without live pressure, consider an external rod lock or the SAIL/BSAID series. The overall length is longer than a single-rod SAI to accommodate the rear rod protrusion.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID40 Double Rod Cylinder SAID40AX195S FAQ
Because the double-rod design has the same effective piston area on both sides, it generates 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa in both extend and retract directions.
Yes, as an ISO 15552 profile cylinder, it is dimensionally interchangeable with other standard ISO 15552 double-rod cylinders, provided you account for the PT tapered port and rear-rod clearance.
