Airtac SAID40 Double Rod Cylinder SAID40BX150S
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40BX150S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 150mm 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 SAID40BX150S
The AirTAC SAID40X150-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a rod out of both end covers, yielding identical extend and retract forces. Because the annulus area is symmetrical, you get 528 N of thrust each way at 0.5 MPa (and 739 N at 0.7 MPa). The integrated magnet (-S) enables position detection, while the SUS304 stainless steel rods (code B) offer high corrosion resistance.
This through-rod design lets you mount the primary workpiece on one end and a cam, guide, or limit flag on the rear. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. Adjustable air cushions at both ends absorb impact, but note that a plain SAID does not hold its load if air pressure is lost.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX150S Is Used
Symmetric Force Transfer
Ideal for pushing and pulling loads requiring identical 528 N forces in both directions without speed discrepancies.
Anti-Rotation Slides
The twin SUS304 rods keep the payload guided and prevent unwanted rotation during linear travel.
Through-Rod Sensing
Drive the main tool on the front while using the rear rod end to trigger CMSE or DMSE position sensors.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX150S the Right Cylinder?
Select this 40 mm bore when an application demands equal push and pull forces alongside anti-rotation stability. If you need less force, the 32 mm bore provides 345 N both ways at 0.5 MPa; stepping up to the 50 mm bore yields 825 N. The double-rod architecture is preferred over a single-rod SAI when you need to drive a secondary mechanism from the rear or require twin-side guidance. The PT tapered ports and G1/4 port size are fixed for this bore.
For dimensionally interchangeable drop-in replacements, match the 40 mm bore, 150 mm stroke, and ISO 15552 mounting interface. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (FB, CA, CB, and CR are reserved for single-rod variants). Because the rear rod protrudes from the back cover, ensure you leave adequate clearance. Remember that the adjustable cushions only decelerate the piston near stroke end; they do not lock the load.
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 SAID40BX150S FAQ
Because the double-rod design has equal piston areas on both sides, the force is identical in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
Yes, the SAID40X150-S is dimensionally interchangeable per ISO 15552. Just ensure your mounting accessory matches the SAID's available set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and that you have rear clearance for the protruding rod.
