About the Airtac SAID80 Double Rod Cylinder SAID80X50
The AirTAC SAID80X50 is a double-acting, double-rod ISO 15552 profile cylinder engineered for applications requiring equal force and speed in both directions. Because a rod exits both ends of the piston, the effective annulus area is identical on extend and retract, yielding a consistent 2268 N output each way at 0.5 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting.
This through-rod design allows you to attach a primary workpiece on the front thread and a rear cam or position flag on the M20x1.5 rod end. It utilizes a standard carbon steel rod and PT tapered port threads. For high-temperature environments up to +70 C, seal options such as Viton H can be specified to maintain reliable operation.

Where the Airtac SAID80 Double Rod Cylinder SAID80X50 Is Used
Anti-Rotation Slides
The twin-rod construction prevents piston rotation during traverse, providing precise linear guidance for heavy sliding carriers without external guides.
Symmetric-Force Transfer
Delivers an identical 2268 N force on both extend and retract strokes to smoothly shuttle components between two processing stations.
Rear-Flag Sensing
The protruding rear rod end serves as an excellent mounting point for a physical limit flag, allowing external position verification on non-magnet setups.
Is the Airtac SAID80 Double Rod Cylinder SAID80X50 the Right Cylinder?
Choose this 80 mm bore when an application demands substantial bidirectional thrust that a smaller 63 mm bore (1402 N at 0.5 MPa) cannot provide, but without the full force of a 100 mm option (3681 N). The double-rod architecture is selected over a single-rod SAI when the load requires strict anti-rotation guidance or dual-station actuation. To achieve drop-in compatibility with other ISO 15552 cylinders, match the 80 mm bore, 50 mm stroke, G3/8 port, and appropriate mounting accessory.
Note that the variable air cushions at both ends only decelerate the piston near stroke end and do not function as a lock. If the mechanism must hold a load without live air pressure, an external pilot-operated check valve or a related locking type like BSAID is required. Since this is a non-magnet variant, position sensing requires external physical stops or limit flags rather than internal CMSE or DMSE switches.
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 SAID80 Double Rod Cylinder SAID80X50 FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 2268 N in both directions at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. The SAID series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR styles found on single-rod variants.
