About the Airtac SAID40 Double Rod Cylinder SAID40AX1000S
The AirTAC SAID40X1000-S is a double-acting, double-rod pneumatic cylinder built to ISO 15552 dimensional standards, featuring a 40mm bore and a 1000mm made-to-order stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding exactly 528 N of force in both extend and retract directions at 0.5 MPa. This equal-force characteristic makes it a drop-in replacement for other ISO 15552 double-rod cylinders.
This variant includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. It features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rear rod protrusion requires additional clearance space in your machine layout.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX1000S Is Used
Symmetric Force Transfer
Drives a transfer carriage with identical 528N thrust and speed in both directions, ensuring perfectly synchronized motion without asymmetric acceleration.
Anti-Rotation Slides
Uses the twin-rod geometry to guide a heavy sliding fixture, preventing unwanted rotation and eliminating the need for a separate external guide rail.
Rear-Cam Actuation
Mounts the primary workpiece on the front rod and a cam or position flag on the rear protruding rod to trigger external mechanical switches or limit sensors.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX1000S the Right Cylinder?
Select this 40mm bore model over the smaller 32mm (345 N) when you need slightly higher symmetric thrust, or step up to the 50mm bore (825 N) for heavier loads. The double-rod design is chosen over a single-rod SAI when an application demands anti-rotation guidance, twin-station actuation, or a rear-mounted position flag. With a 1000mm stroke, the long unsupported rod is highly susceptible to side-load bending; always use an external guide to prevent rod-bearing damage.
Ensure your ISO 15552 replacement matches the 40mm bore, 1000mm stroke, PT port threads, and the required mounting accessory from the SAID set: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (FB, CA, CB, and CR are omitted). Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If position holding without live air pressure is required, use an external pilot-operated check valve or a BSAID clamp-lock cylinder.
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 SAID40AX1000S 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 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
Yes, as a profile-type ISO 15552 cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Just match the 40mm bore, 1000mm stroke, PT port threads, and the appropriate mounting accessory.
