About the Airtac SAID40 Double Rod Cylinder SAID40AX750S
The AirTAC SAID40X750-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 750mm stroke. A single piston drives a rod out of both end covers, yielding identical extend and retract forces. Because the annulus area is symmetrical, it provides 528N of thrust and pull force at 0.5MPa (739N at 0.7MPa) in either direction.
Equipped with a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side barrel grooves. The rod is crafted from SUS420J2 stainless steel for superior corrosion resistance, and fluid connections use PT tapered threads. This through-rod layout is ideal for mounting a workpiece on one end and a cam or position flag on the opposite side.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX750S Is Used
Symmetric Force Transfer
Ideal for pushing and pulling loads that require identical force and speed in both directions, ensuring smooth synchronous motion without pressure discrepancies.
Anti-Rotation Slides
The twin-rod design naturally resists torsional rotation, providing stable guidance for lifting or sliding heavy vertical loads without external guides.
Through-Rod Sensing
Mount the primary workpiece on the front rod and attach a cam or position flag to the rear rod end to trigger rear-mounted CMSE or DMSE sensors.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX750S the Right Cylinder?
Select this 40mm bore model when an application requires equal push and pull forces, which is the primary advantage of the double-rod design over a single-rod SAI. If your mechanism needs less force, stepping down to a 32mm bore yields 345N both ways, whereas stepping up to a 50mm bore provides 825N. The 750mm stroke falls within the 1200mm maximum standard stroke limit for this bore.
Because the stroke is 750mm, the extended rod length increases the risk of side-load bending on the rod bearing; an external guide rail is highly recommended to prevent premature wear. Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end and do not hold a load if air pressure is lost. For position holding without live pressure, consider an SAIL lock cylinder or an external rod lock. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552 for drop-in replacement of other profile double-rod cylinders.

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 SAID40AX750S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It delivers 528N of force at 0.5MPa, 739N at 0.7MPa, and 950N at 0.9MPa for both extension and retraction.
Yes, as a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other standard double-rod cylinders. It features a PT tapered port thread, a G1/4 port size, and operates at speeds between 30 and 800 mm/s.
