About the Airtac SAID50 Double Rod Cylinder SAID50X115S
The AirTAC SAID50X115-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a through-rod that exits both end covers. Because the rod occupies an equal area on both sides of the piston, the annulus area is identical in both directions, yielding a perfectly symmetric output of 825 N at 0.5 MPa for extend and retract strokes. This 115 mm stroke is a non-standard, made-to-order length that requires rear-rod clearance during machine layout.
Equipped with a magnetic piston (-S), this carbon-steel rod variant directly supports AirTAC CMSE reed and DMSE solid-state sensors via the dual-side extruded aluminum barrel grooves. The PT tapered port threads ensure a tight pneumatic seal, while the twin-rod design provides superior anti-rotation guidance for demanding transfer tasks.

Where the Airtac SAID50 Double Rod Cylinder SAID50X115S Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place gantry where the equal 825 N force both ways ensures stable, jerk-free material transfer without momentum imbalances.
Rear-Rod Cam Actuation
Uses the protruding rear rod to trigger a mechanical limit flag or secondary cam mechanism, keeping the primary work tool and sensor feedback perfectly synchronized.
Anti-Rotation Guide Slide
Leverages the twin-rod architecture to prevent piston rotation, guiding a heavy vertical slide payload that would otherwise bind in a single-rod setup.
Is the Airtac SAID50 Double Rod Cylinder SAID50X115S the Right Cylinder?
Select this 50 mm bore cylinder when an application demands equal push and pull forces, such as 825 N at 0.5 MPa, alongside strict anti-rotation control. If your mechanism requires higher thrust, stepping up to the 63 mm bore yields 1402 N both ways; if less force is needed, the 40 mm bore provides 528 N. The defining advantage of this SAID over a single-rod SAI is the rear protruding rod, which can mount a secondary cam, position flag, or drive a second mechanism simultaneously.
This model includes the -S magnet for position sensing and uses a PT G1/4 port. It is dimensionally interchangeable per ISO 15552 for drop-in replacement of other double-rod profile cylinders. Note that a plain SAID does not hold its load when air is removed; if the valve is centered or pressure drops, the piston drifts. For position holding, consider a SAIL lock cylinder, a BSAID clamp-lock, or an external pilot-operated check valve.

- ✓ 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 SAID50X115S FAQ
Because the double-rod design has the rod area subtracted from both sides of the piston, the extend and retract forces are equal. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa in both directions.
Yes, the SAID50X115-S is dimensionally interchangeable per ISO 15552 profile cylinder standards. It uses the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and serves as a drop-in replacement for other ISO 15552 double-rod cylinders.
