About the Airtac SAID40 Double Rod Cylinder SAID40AX75S
The AirTAC SAID40X75-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a rod out of both end covers, meaning the annulus area is identical on extend and retract. This yields equal push and pull forces, generating exactly 528 N of thrust each way at 0.5 MPa and 739 N at 0.7 MPa.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. The -S suffix denotes an integrated magnet, enabling position tracking via CMSE reed or DMSE electronic solid-state sensors mounted in the dual-side extruded barrel grooves. PT tapered ports (G1/4) ensure a tight pneumatic seal.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX75S Is Used
Symmetric Transfer
Drives a transfer shuttle where the equal 528N both-way force ensures identical push and pull dynamics for parts moving in either direction.
Anti-Rotation Slide
Twin rods exiting both ends keep the piston guided against rotation, ideal for lifting and positioning flat panels without a separate guide rail.
Dual-Station Actuation
The primary rod strokes a clamping fixture while the rear rod simultaneously trips a mechanical limit flag on a secondary station.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX75S the Right Cylinder?
Select this 40mm bore, 75mm stroke model when an application demands symmetric force and speed in both directions, or requires a rear-rod extension to mount a secondary cam, position flag, or separate mechanism. If you need higher thrust, stepping up to the 50mm bore yields 825 N each way at 0.5 MPa, while dropping to the 32mm bore reduces it to 345 N. Because the rod exits both ends, you must account for extra rear clearance in your layout.
This unit is dimensionally interchangeable per ISO 15552, acting as a drop-in replacement for other ISO 15552 double-rod cylinders without claiming brand equivalence. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR variants. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock or hold the load. If pneumatic pressure is lost, the cylinder drifts. For dead-load holding, consider an external rod lock or the SAIL/BSAID series.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAID40AX75S FAQ
Because the rod occupies both sides of the piston, the effective area is the same in both directions. It provides 528 N of force both extending and retracting at 0.5 MPa, and 739 N at 0.7 MPa.
Yes, it is a true ISO 15552 profile cylinder, so its mounting interface dimensions are interchangeable with other ISO 15552 double-rod cylinders. It uses PT ports and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
