About the Airtac SAID40 Double Rod Cylinder SAID40AX165S
The AirTAC SAID40X165-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 165mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding a perfectly symmetrical 528N of force in both directions at 0.5 MPa. The -S suffix denotes an integrated magnet for position sensing.
This variant is configured with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and PT tapered port threads. The twin-rod architecture allows you to mount the primary workpiece on one end while utilizing the rear rod end for a cam, position flag, or secondary mechanism. It features adjustable air cushions at both ends and dual-side sensor grooves compatible with AirTAC CMSE reed and DMSE solid-state switches.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX165S Is Used
Symmetric Transfer Unit
Drives a shuttle mechanism where identical 528N extend and retract forces ensure perfectly balanced, smooth part transfer without speed fluctuations.
Dual-Side Tooling Actuator
Mounts a primary gripper on the front rod while using the rear rod end to trigger a DMSE solid-state sensor flag for mid-stroke confirmation.
Anti-Rotation Guide Slide
The twin-rod construction prevents piston rotation during vertical lifting, guiding the load securely without needing an external linear bearing.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX165S the Right Cylinder?
Select this 40mm bore when an application strictly requires equal push and pull forces alongside anti-rotation guidance. If you need slightly less force, the 32mm bore offers 345N both ways; if your payload demands more, stepping up to the 50mm bore provides 1154N at 0.7 MPa. The double-rod design is specifically chosen over a single-rod SAI when a machine layout demands dual-side actuation or rear-rod feedback. Remember that the adjustable cushions only decelerate the piston near stroke end; they do not hold a load. If your process requires position holding upon air loss, you must use an external rod lock or pilot-operated check valve. For ISO 15552 interchangeability, match the 40mm bore, 165mm stroke, PT port, and mounting accessory.
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 SAID40AX165S FAQ
Because the rod area is subtracted on both sides, the SAID40X165-S generates equal force in both directions. It provides 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa.
Yes, it is dimensionally interchangeable with ISO 15552 cylinders, but the SAID uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits FB, CA, CB, and CR mounts which are single-rod only.
