About the Airtac SAID100 Double Rod Cylinder SAID100AX140
The AirTAC SAID100X140 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 140mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal extend and retract force of 3681N at 0.5MPa. This symmetric thrust makes the unit ideal for transferring loads without deceleration mismatches.
Equipped with a SUS420J2 stainless steel rod (material code A), it provides robust corrosion resistance for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the rear rod end can drive a secondary mechanism or carry a position flag. It features adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX140 Is Used
Symmetric Force Transfer
Drives a workpiece back and forth across a conveyor with identical push and pull force, preventing speed variations between extend and retract strokes.
Anti-Rotation Slides
Guides heavy machining fixtures using the dual rods exiting both end covers, ensuring the load resists twisting during high-torque cutting operations.
Rear-Side Sensing
Utilizes the protruding rear rod end to mount a physical cam or position flag, triggering external limit switches without interfering with the primary work area.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX140 the Right Cylinder?
Select this 100mm bore when an application requires balanced bidirectional power, as the SAID100X140 outputs 3681N of force both ways at 0.5MPa. If your project needs less thrust, stepping down to an 80mm bore yields 2268N both ways, whereas a 125mm bore offers 5734N. Engineers choose the double-rod configuration over a single-rod SAI to achieve superior anti-rotation guidance, mount dual-side tooling, or utilize the rear extension for external limit flags.
This cylinder uses PT tapered port threads and a G1/2 air supply. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR accessories found on single-rod variants. Note that a plain SAID does not hold its position if air pressure is lost; the piston will drift when the valve centers. For load-holding requirements, consider an external pilot-operated check valve or a BSAID clamp-lock cylinder. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders.

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 SAID100AX140 FAQ
The SAID100X140 provides equal force in both directions due to its double-rod design. It delivers 3681N at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa for both extension and retraction.
Yes. The SAID100X140 is an ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It shares the same mounting interface and barrel profile, though it uses a reduced set of mounting accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2).
