Airtac SAID40 Double Rod Cylinder SAID40X5
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40X5 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 5mm 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 SAID40X5
The AirTAC SAID40X5 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 5mm stroke. Because a carbon steel rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 528N of force in both directions at 0.5 MPa. This through-rod layout provides inherent anti-rotation guidance for tightly spaced mechanisms.
The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. It uses a PT tapered G1/4 port, omits the FB CA CB CR mounts of single-rod SAI types, and relies on adjustable air cushions at both ends to decelerate the piston rather than hold a load.

Where the Airtac SAID40 Double Rod Cylinder SAID40X5 Is Used
Short-Stroke Clamping
Provides symmetric hold and release force for securing thin workpieces in machining fixtures.
Symmetric Transfer
Drives a dual-sided ejection mechanism where the rear rod simultaneously actuates a parts diverter.
Anti-Rotation Guide
Prevents piston twisting during high-frequency micro-movements in automated assembly slides.
Is the Airtac SAID40 Double Rod Cylinder SAID40X5 the Right Cylinder?
Select this 5mm stroke model for very short clamping or ejecting duties where space is minimal. If your application requires slightly higher thrust, stepping up to the 50mm bore neighbor provides 825N both ways at 0.5 MPa. Choose the SAID twin-rod design over a single-rod SAI when you need to drive a cam or position flag out of the rear cover while actively resisting side-load twisting.
Ensure your setup matches the ISO 15552 mounting interface dimensions using Basic, FA, LB, TC, FTC, TCM1, or TCM2 accessories. Remember that a plain SAID cylinder will drift if air pressure is lost; for position holding, consider an external rod lock or the SAIL lock variant.
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 SAID40X5 FAQ
It delivers 528N in both extend and retract directions at 0.5 MPa, and 739N both ways at 0.7 MPa, because the double-rod design creates equal annulus areas on both sides.
Yes, it is dimensionally interchangeable with other ISO 15552 profile cylinders, but ensure your design accommodates the rear rod protrusion and uses the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
