About the Airtac SAID40 Double Rod Cylinder SAID40BX230
The AirTAC SAID40X230 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 230 mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on extension and retraction. This provides an equal force of 528 N in both directions at 0.5 MPa, ensuring perfectly symmetric motion.
This specific configuration utilizes a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, allowing you to mount a rear-position flag or cam on the secondary rod end to trigger external mechanisms while driving the primary load.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX230 Is Used
Symmetric Transfer
Drives a parts shuttle back and forth with identical 528 N force and speed in both directions, ensuring consistent cycle times without tuning separate pressure regulators.
Dual-Station Actuation
Mounts a primary workpiece on the front rod and a secondary cam or tool on the rear rod to operate two synchronized mechanisms from one piston.
Anti-Rotation Slides
The twin-rod geometry prevents the attached load from twisting during vertical lifting, maintaining precise linear guidance without external rails.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX230 the Right Cylinder?
Select this 40 mm bore when an application requires matched push and pull dynamics that a single-rod SAI cannot provide. If your project demands less force, the 32 mm bore offers 345 N both ways; stepping up to a 50 mm bore yields 825 N. The twin-rod design inherently improves load guidance and resists torsion better than a single rod.
Because this model lacks a lock mechanism, it cannot hold a load if air pressure drops; use a SAIL or BSAID variant if fail-safe braking is required. As a true ISO 15552 profile cylinder, it drops into existing footprints and uses the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the 230 mm stroke is relatively long, ensure an external guide supports the load to prevent rod-bearing bending under side loads.

- ✓ 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 SAID40BX230 FAQ
The double-rod design provides equal force in both directions. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa for both extension and retraction.
Yes. The SAID40X230 is dimensionally interchangeable per ISO 15552. It uses standard mounting dimensions and a G1/4 port, making it a direct drop-in replacement for other ISO 15552 double-rod cylinders.
