Airtac SAID100 Double Rod Cylinder SAID100X185S
The AirTAC Airtac SAID100 Double Rod Cylinder SAID100X185S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 185mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID100 Double Rod Cylinder SAID100X185S
The AirTAC SAID100X185-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and a 185mm non-standard stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding exactly 3681N of thrust and pull force at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent kinetic behavior in both travel directions.
Equipped with a magnet (-S), this variant directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors mounted into the dual-side extruded barrel grooves. The standard carbon steel rod provides durable service, while the rear rod extension allows engineers to mount a secondary cam, position flag, or drive a second mechanism for synchronized dual-station actuation.

Where the Airtac SAID100 Double Rod Cylinder SAID100X185S Is Used
Dual-Station Actuation
Drives two separate workstations simultaneously from a single piston, using the front rod for the primary task and the rear rod for a secondary synchronized operation.
Anti-Rotation Slides
The twin-rod geometry prevents piston rotation during travel, providing stable linear guidance for precision sliding fixtures without external guides.
Through-Rod Sensing
Mounts a physical cam or position flag on the rear rod end to trigger external mechanical limit switches, while the internal magnet works with DMSE sensors.
Is the Airtac SAID100 Double Rod Cylinder SAID100X185S the Right Cylinder?
Select this 100mm bore when an application demands equal push and pull forces (3681N at 0.5 MPa) alongside anti-rotation guidance. If your mechanism requires less force, stepping down to the 80mm bore yields 2268N both ways; if more power is needed, the 125mm bore offers 5734N. The double-rod design inherently resists torsional loads better than a single-rod SAI, though for this 185mm stroke you should verify bearing loads. Note that the overall length is longer than a single-rod cylinder because the rear rod protrudes, requiring extra clearance.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard double-rod units. It uses a reduced mounting accessory set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The PT port thread matches the G1/2 bore specification. Remember that the adjustable air cushions only decelerate the piston near stroke end; this cylinder will drift and cannot hold a load if air pressure is lost. For dead-load holding, consider an external rod lock or the BSAID clamp-lock variant.
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 SAID100X185S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 3681N in both directions at 0.5 MPa, 5153N at 0.7 MPa, and 6626N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. It shares the same mounting footprint and G1/2 port size, but note the rear rod requires additional clearance and it uses a specific mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
