About the Airtac SAID100 Double Rod Cylinder SAID100X40
The AirTAC SAID100X40 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 40mm stroke. A single piston drives a 25mm carbon steel rod out of both end covers, yielding equal extend and retract forces of 3681 N at 0.5 MPa. This symmetric thrust makes it ideal for mechanisms requiring consistent power in both travel directions.
Because the rod exits both ends, you can attach the primary workpiece at the front and mount a cam, position flag, or secondary tool at the rear. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE solid-state switches. It uses a G1/2 port and offers adjustable air cushions at both ends to smoothly decelerate the payload.

Where the Airtac SAID100 Double Rod Cylinder SAID100X40 Is Used
Symmetric Force Transfer
Drives heavy equal-force push and pull mechanisms where the 3681 N output at 0.5 MPa must remain identical in both directions without speed variation.
Twin-Station Actuation
Simultaneously operates two separate stations or tools, mounting the primary workpiece on the front rod extension and a secondary mechanism on the rear.
Anti-Rotation Slides
Keeps guided loads perfectly aligned against rotational torque by utilizing the dual-rod architecture exiting both end covers for stable linear movement.
Is the Airtac SAID100 Double Rod Cylinder SAID100X40 the Right Cylinder?
Select this 100mm bore when an application demands high bidirectional force, as it provides 3681 N each way at 0.5 MPa. If your payload is lighter, stepping down to an 80mm bore drops the both-way force to 2268 N, whereas a larger 125mm bore raises it to 5734 N. Choose the SAID double-rod configuration over a single-rod SAI when you need twin-side guidance to prevent rotation or require rear-rod actuation. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
This cylinder uses a PT tapered G1/2 port thread. Since the stroke is only 40mm, side-load stress on the rod bearing is minimal. Note that the adjustable cushions only decelerate the piston near stroke end; they do not lock the load. If your system loses air pressure, the piston will drift, so an external pilot-operated check valve or a BSAID clamp-lock cylinder is required for position holding.
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 SAID100 Double Rod Cylinder SAID100X40 FAQ
Because the 25mm rod occupies both sides of the piston, the effective area is identical in both directions. It delivers an equal push and pull force of 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes. The SAID100X40 is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other standard profile double-rod cylinders. It uses a G1/2 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories.
