About the Airtac SAID50 Double Rod Cylinder SAID50AX70S
The AirTAC SAID50X70-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 70mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in both directions, yielding a perfectly balanced thrust of 825N on extend and retract at 0.5MPa. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for non-contact position detection.
Equipped with a SUS420J2 stainless steel rod (material code A), this variant provides enhanced corrosion resistance over standard carbon steel. A single piston drives a rod out of both end covers, allowing you to mount the primary workpiece on one side and a mechanical cam, second tool, or limit flag on the rear rod end. It uses adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX70S Is Used
Symmetric Force Transfer
Ideal for pressing or transferring loads where the 825N thrust must remain identical in both directions without speed variation.
Dual-Side Actuation
Mount the primary workpiece on the front rod and a secondary cam or position flag on the rear rod to trigger external mechanisms.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, providing precise linear guidance for sliding or lifting modules.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX70S the Right Cylinder?
Select this 50mm bore model when an application demands equal push and pull forces alongside anti-rotation guidance. If your mechanism requires less force, stepping down to the 40mm bore offers 528N both ways at 0.5MPa; if higher thrust is needed, the 63mm bore provides 1402N. The double-rod design is preferred over a single-rod SAI when a secondary action or sensor target is required at the rear of the machine, ensuring twin-side load guidance. This unit uses PT tapered port threads (G1/4) and operates at speeds of 30-800mm/s.
Remember that the adjustable air cushions only slow the piston near stroke end; they do not lock or hold the load. If power or air pressure drops, the cylinder will drift, so an external pilot-operated check valve or a SAIL lock cylinder is required for position holding. This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.

- ✓ 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 SAID50AX70S FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers an equal push and pull force of 825N at 0.5MPa, 1154N at 0.7MPa, and 1484N at 0.9MPa.
Yes, the SAID50X70-S is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders and uses the standard Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories.
