About the Airtac SAID50 Double Rod Cylinder SAID50X90
The AirTAC SAID50X90 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 90mm stroke. Because a carbon steel rod exits both end covers, the effective piston area is identical on extend and retract, yielding exactly 825N of force both ways at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This through-rod design allows you to attach a workpiece on one end and a cam, position flag, or secondary mechanism on the rear rod. It provides superior dual-side guidance and prevents rotation compared to a single-rod SAI cylinder.

Where the Airtac SAID50 Double Rod Cylinder SAID50X90 Is Used
Symmetric Force Transfer
Drives equal push and pull loads of 825N at 0.5 MPa, ideal for machinery requiring consistent velocity and force in both directions.
Anti-Rotation Slides
The twin carbon steel rods prevent piston rotation, providing precise linear guidance for lifting and indexing rigid platforms.
Through-Rod Sensing
Mounts a cam or position flag on the rear rod to trigger external DMSE electronic sensors without interfering with the primary work tool.
Is the Airtac SAID50 Double Rod Cylinder SAID50X90 the Right Cylinder?
Choose this 50mm bore when an application demands equal push and pull forces alongside anti-rotation stability. If your project requires less force, the 40mm neighbor provides 528N each way at 0.5 MPa; for heavier loads, the 63mm bore offers 1402N. The PT tapered port threads ensure a tight pneumatic seal, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.
Because this is a double-rod variant, you must account for the rear rod protruding from the back cover and provide adequate clearance. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding without live pressure is required, consider an external rod lock or the BSAID clamp-lock series.
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 SAID50 Double Rod Cylinder SAID50X90 FAQ
The SAID50X90 double-rod cylinder provides equal force in both directions due to the twin rods. It outputs 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 profile cylinder standards. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing a standard PT G1/4 port and standard mounting brackets.
