About the Airtac SAID50 Double Rod Cylinder SAID50AX1000S
The AirTAC SAID50X1000-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 1000 mm stroke. Because a piston rod exits both end covers, the annulus area is identical on both sides, yielding equal push and pull forces of 825 N at 0.5 MPa. This through-rod design is ideal for anti-rotation guidance and dual-side actuation.
Equipped with a magnet for position sensing, this variant works seamlessly with AirTAC CMSE reed and DMSE solid-state switches mounted in the dual sensor grooves. It features a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads, ensuring a dimensionally interchangeable drop-in replacement for other ISO 15552 twin-rod cylinders.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX1000S Is Used
Symmetric Force Transfer
Drives loads with identical 825 N push and pull forces, ensuring perfectly balanced momentum and velocity in both directions for precision transfer arms.
Anti-Rotation Slides
The twin-rod through-design prevents the piston from twisting under offset loads, keeping vertical lifting slides perfectly aligned without rotational drift.
Through-Rod Sensing
Mounts work tools on the front rod and CMSE/DMSE position flags on the rear protruding rod, allowing isolated sensor placement away from the main work area.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX1000S the Right Cylinder?
Choose this 50 mm bore model when an application requires exactly 825 N of symmetric force at 0.5 MPa, stepping up from the 40 mm bore (528 N) or down from the 63 mm bore (1402 N). A double-rod configuration is preferred over a single-rod SAI when you need to mount a cam or position flag on the rear rod, or when superior resistance to torsional rotation is required.
For a 1000 mm stroke, the extended length is significantly longer than a single-rod cylinder because the rear rod protrudes continuously; ensure you have adequate clearance. At this stroke length, the 20 mm rod and M16x1.5 thread face substantial bending moments under side loads, so an external guide rail is strongly recommended. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end and do not hold the load; if position holding without live pressure is needed, consider an external rod lock or the BSAID clamp-lock series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID50 Double Rod Cylinder SAID50AX1000S FAQ
It provides 825 N of force at 0.5 MPa and 1154 N at 0.7 MPa. Because it is a double-rod cylinder, the annulus area is the same on both sides, meaning the push and pull forces are exactly equal.
Yes, it is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a PT G1/4 port and a 20 mm SUS420J2 rod.
