About the Airtac SAID100 Double Rod Cylinder SAID100X85
The AirTAC SAID100X85 is a double-acting, double-rod profile cylinder built to ISO 15552 mounting dimensions. A rod extends from both end covers, yielding equal extend and retract forces of 3681N at 0.5MPa. This symmetric force profile makes it a drop-in replacement for other ISO 15552 twin-rod units.
The twin rods allow you to drive a primary workpiece on one end while mounting a cam or position flag on the rear rod. It features an extruded aluminum barrel with sensor grooves on both sides. Without a magnet, it relies on external limit switches, though adding an -S magnet enables CMSE reed or DMSE solid-state sensors.

Where the Airtac SAID100 Double Rod Cylinder SAID100X85 Is Used
Symmetric Transfer
Drives a parts shuttle back and forth across a conveyor, utilizing the identical 3681N force and matching speed in both directions for consistent cycle times.
Anti-Rotation Slides
Keeps a heavy machining fixture guided and prevented from twisting during transit, using the twin rods exiting both covers for superior stability.
Twin-Station Actuation
Actuates a primary clamping mechanism on the front rod end while simultaneously driving a mechanical sequence flag on the rear rod end.
Is the Airtac SAID100 Double Rod Cylinder SAID100X85 the Right Cylinder?
Choose this 100mm bore over the 80mm option (2268N both ways at 0.5MPa) when your application demands higher bidirectional force, or step down if 3681N is excessive. A double-rod design is selected over a single-rod SAI when precise anti-rotation guidance or dual-side actuation is required. The 25mm carbon steel rod and M20x1.5 thread handle substantial side loads, but external guidance is still recommended for heavy offsets.
This standard 85mm stroke uses a G1/2 PT port. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If unpowered position holding is needed, use a SAIL or BSAID variant. The SAID mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAID100 Double Rod Cylinder SAID100X85 FAQ
Because the double-rod design creates equal annulus areas on both sides, it provides 3681N of force in both extend and retract directions at 0.5MPa, and 5153N at 0.7MPa.
Yes, the SAID100X85 is dimensionally interchangeable per ISO 15552. It functions as a drop-in replacement for other ISO 15552 double-rod profile cylinders, using the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces.
