About the Airtac SAID40 Double Rod Cylinder SAID40X95S
The AirTAC SAID40X95-S is a double-acting, double-rod ISO 15552 profile cylinder with a 40mm bore and 95mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding a balanced 528N output force at 0.5 MPa in either direction. The integrated -S magnet pairs directly with CMSE reed and DMSE electronic sensors mounted in the dual side grooves.
This through-rod architecture allows engineers to mount the primary workpiece on one end while attaching a position flag or mechanical cam to the rear rod. The PT-tapered G1/4 port ensures secure pneumatic fitting, and the extruded aluminum barrel keeps the assembly lightweight without sacrificing structural rigidity.

Where the Airtac SAID40 Double Rod Cylinder SAID40X95S Is Used
Symmetric Force Transfer
Ideal for shuttle mechanisms requiring identical push and pull dynamics, using the equal annulus area to maintain steady motion profiles in both directions.
Anti-Rotation Slides
The twin-rod design naturally resists torsional twist, providing superior load guidance for lifting vertical stages without binding or uneven wear.
Rear-Rod Sensing
The protruding rear rod offers a dedicated mounting point for a position flag, driving external limit switches while the primary tool operates the workpiece.
Is the Airtac SAID40 Double Rod Cylinder SAID40X95S the Right Cylinder?
Choose this 40mm bore when an application demands equal push and pull velocities or anti-rotation guidance that a single-rod SAI cannot provide. If your process requires less force, stepping down to the 32mm bore offers 345N at 0.5 MPa, while moving up to the 50mm bore provides 825N. The 95mm stroke is a standard length, keeping overall dimensions predictable for machine layout.
Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock or hold the load. If unpressurized drift causes safety issues, consider an external pilot-operated check valve or a BSAID clamp-lock variant. This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders.

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 SAID40X95S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It provides 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa.
Yes. The SAID40X95-S is a profile cylinder built to the ISO 15552 mounting interface, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a PT G1/4 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
