About the Airtac SAID100 Double Rod Cylinder SAID100BX145
The AirTAC SAID100X145 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 end covers, the annulus area is identical on extend and retract, yielding a balanced 3681 N of thrust each way at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance and allows a secondary mechanism to be driven from the rear.
This specific configuration features SUS304 stainless steel rods for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to mount position switches along either rod end. It shares the exact mounting footprint of standard ISO 15552 cylinders for seamless drop-in integration.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX145 Is Used
Symmetric-Force Transfer
Drives a heavy workpiece back and forth with exactly 3681 N of force in both directions, preventing speed fluctuations caused by differential piston areas.
Anti-Rotation Slides
Uses the dual protruding rods to guide heavy vertical loads without twisting, eliminating the need for external linear bearings in compact spaces.
Dual-Station Actuation
Mounts the primary tool on the front rod end and a secondary cam or limit flag on the rear rod end to trigger mechanical switches behind the cylinder.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX145 the Right Cylinder?
Selecting this 100 mm bore makes sense when your process demands substantial symmetric force, stepping up from a 80 mm bore that provides 2268 N at 0.5 MPa. The twin-rod architecture is chosen over a single-rod SAI when the load requires strict anti-rotation control or when a rear cam and position flag must trigger external limits. Note that while the adjustable air cushions at both ends decelerate the piston near stroke end, they do not hold the load; if pressure drops, the cylinder drifts, requiring an external rod lock or a BSAID clamp-lock for fail-safe positioning.
To match this exact unit, specify the 100 mm bore, 145 mm stroke, PT port threads, and SUS304 rod material. It uses the reduced SAID mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod variants. As this model lacks the -S magnet suffix, it cannot host reed or electronic sensors without a configuration change.

- ✓ 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 SAID100BX145 FAQ
Because the double-rod design occupies volume on both sides of the piston, the effective area is equal in both directions. It provides 3681 N of force at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa on both extend and retract strokes.
Yes, it is dimensionally interchangeable with other ISO 15552 profile cylinders. However, the SAID series uses a reduced mounting set consisting of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR styles found on single-rod versions.
