Airtac SAID40 Double Rod Cylinder SAID40X375
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40X375 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 375mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID40 Double Rod Cylinder SAID40X375
The AirTAC SAID40X375 is a double-acting, double-rod ISO 15552 profile cylinder engineered to deliver 528N of force in both extend and retract directions at 0.5 MPa. Because a carbon steel rod exits both end covers, the annulus area is identical on each side, ensuring perfectly matched push and pull dynamics.
This through-rod architecture allows you to mount the primary workpiece on the front thread while using the rear M12x1.25 rod end for a position flag, cam, or secondary mechanism. The extruded aluminum barrel features sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later.

Where the Airtac SAID40 Double Rod Cylinder SAID40X375 Is Used
Symmetric Force Transfer
Drives loads requiring identical push and pull dynamics, leveraging the equal 528N annulus area to maintain consistent velocity and torque during bidirectional transfers.
Dual-Station Actuation
Operates two separate tooling stations simultaneously by mounting a workpiece on the front rod end and a secondary mechanism on the rear M12x1.25 thread.
Anti-Rotation Slides
Keeps guided loads from twisting during the 375mm stroke by using the twin-rod architecture to resist torsional forces better than a single-rod cylinder.
Is the Airtac SAID40 Double Rod Cylinder SAID40X375 the Right Cylinder?
Selecting this 40mm bore over the neighboring 32mm variant upgrades your bidirectional force from 345N to 528N, while stepping up to the 63mm bore yields 1402N. The double-rod design is specifically chosen when an application demands superior anti-rotation resistance or requires driving two separate mechanisms simultaneously, a distinct advantage over a single-rod SAI.
With a 375mm stroke, the unsupported piston rod is highly susceptible to bending under side loads; always utilize an external linear guide to prevent premature bearing wear. Remember that the adjustable air cushions only decelerate the piston near stroke ends and do not hold the load if air pressure drops—add an external pilot-operated check valve if static locking is needed. This model is dimensionally interchangeable per ISO 15552 and uses PT tapered ports.
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 SAID40X375 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It outputs 528N in both directions at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa.
Yes, the SAID40X375 is dimensionally interchangeable per ISO 15552 and uses a standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), making it a drop-in replacement for comparable profile cylinders.
