About the Airtac SAID100 Double Rod Cylinder SAID100AX145
The AirTAC SAID100X145 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 145mm stroke. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 3681 N of output force in both extend and retract directions at 0.5 MPa. This symmetric force capability makes it ideal for mechanisms requiring equal push and pull dynamics.
This specific configuration utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, paired with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount position switches along either rod extension. Note that a rod protrudes from the rear cover, requiring additional clearance in your machine frame compared to a single-rod SAI.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX145 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the equal 3681 N push and pull forces prevent jerky movements during bidirectional material handling.
Anti-Rotation Slides
The twin-rod architecture keeps heavy workpiece slides perfectly aligned without needing external guide rails, resisting torsional deflection.
Rear-Rod Cam Actuation
Uses the rear protruding rod to trigger a mechanical limit valve or cam, while the front rod performs the primary workpiece clamping action.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX145 the Right Cylinder?
Selecting this 100mm bore double-rod cylinder is optimal when your application demands equal force both ways (3681 N at 0.5 MPa) and superior anti-rotation guidance. If your mechanism requires less force, stepping down to the 80mm bore provides 2268 N, while moving up to the 125mm bore offers 5734 N. The twin-rod design inherently resists torsional loads better than a single-rod SAI, keeping the workpiece guided smoothly.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard profile cylinders with matching 100mm bore and 145mm stroke specifications. Ensure you order the -S magnet option if you intend to use AirTAC CMSE (reed) or DMSE (electronic) solid-state sensors, as this base unit lacks a magnet. Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load. If air pressure is lost, the cylinder will drift, requiring an external pilot-operated check valve or a BSAID clamp-lock for true position holding.
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 SAID100AX145 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides an equal force of 3681 N in both the extend and retract directions at 0.5 MPa (5153 N at 0.7 MPa).
Yes, the SAID100X145 is dimensionally interchangeable per ISO 15552. It shares the standard 100mm bore mounting interface and uses the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories, though you must account for the rear rod protrusion in your design.
