About the Airtac SAID100 Double Rod Cylinder SAID100X550
The AirTAC SAID100X550 is a double-acting, double-rod profile cylinder conforming to ISO 15552 standards. Equipped with a 25mm carbon steel rod exiting both end covers, it delivers an equal 3681N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
Because the twin rods occupy piston area on both sides, push and pull forces are identical, preventing speed discrepancies during cycling. The rear rod extension is ideal for mounting a cam, position flag, or secondary mechanism. This 550mm stroke unit uses a G1/2 port and adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAID100 Double Rod Cylinder SAID100X550 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where equal push and pull power (3681N at 0.5 MPa) ensures consistent cycle times in both directions without speed drift.
Anti-Rotation Slides
Twin rods guide the load rigidly against twisting forces, ideal for precision sliding beds that cannot rotate during extension.
Dual-Side Actuation
Mounts the primary workpiece on the front rod and a position sensing flag on the rear rod to trigger downstream machine logic.
Is the Airtac SAID100 Double Rod Cylinder SAID100X550 the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when an application requires balanced bidirectional force—here, 3681N at 0.5 MPa and 5153N at 0.7 MPa both ways. If your load demands less force, the 80mm bore offers 2268N at 0.5 MPa, while stepping up to 125mm provides 5734N. The double-rod design is chosen over a single-rod SAI when the load needs strict anti-rotation guidance or when a rear rod is needed to actuate a secondary station.
At 550mm stroke, the unsupported rod length increases susceptibility to side-load bending; use an external guide rail to protect the rod bearing. Note that the adjustable cushions only decelerate the piston near stroke end—they do not hold the load. If position holding without air pressure is required, consider a BSAID clamp-lock cylinder or an external pilot-operated check valve. This model uses a PT tapered port thread and standard carbon steel rods. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on single-rod variants.

- ✓ 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 SAID100X550 FAQ
The SAID100X550 provides equal force in both directions due to the double-rod design. It outputs 3681N at 0.5 MPa, 5153N at 0.7 MPa, and 6626N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID100X550 is dimensionally interchangeable per ISO 15552 mounting interface standards. It serves as a direct drop-in replacement for other ISO 15552 double-rod profile cylinders, utilizing a G1/2 port and standard mounting accessories.
