Airtac SAID100 Double Rod Cylinder SAID100X45
The AirTAC Airtac SAID100 Double Rod Cylinder SAID100X45 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 45mm 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 SAID100X45
The AirTAC SAID100X45 is a double-acting, double-rod ISO 15552 profile cylinder where a single piston drives a carbon steel rod out of both end covers. Because the rod occupies an equal area on each side, the annulus is symmetric, yielding an equal 3681 N of thrust at 0.5 MPa on both extend and retract strokes. This twin-rod architecture is purposefully designed so one end can mount the primary workpiece while the opposite end carries a cam, position flag, or secondary mechanism.
The extruded aluminum barrel features sensor grooves on both sides for direct mounting of AirTAC CMSE reed and DMSE electronic switches, though this specific configuration is non-magnetic and requires the -S option for piston sensing. The adjustable air cushions at both ends decelerate the 30-800 mm/s travel speed, but note this cushioning does not lock the piston; if position holding without live air pressure is required, a BSAID clamp-lock or external rod lock is necessary.

Where the Airtac SAID100 Double Rod Cylinder SAID100X45 Is Used
Symmetric Force Transfer
Drives heavy transfer shuttles where the equal 3681 N push and pull forces at 0.5 MPa ensure perfectly balanced acceleration and deceleration of loads in both directions.
Twin-Station Actuation
Utilizes the through-rod design to operate two separate mechanisms or stations simultaneously from a single pneumatic input, saving space and reducing cycle times.
Anti-Rotation Slides
The dual-rod geometry prevents piston rotation, providing the precise linear guidance required for high-accuracy machining and clamping fixtures.
Is the Airtac SAID100 Double Rod Cylinder SAID100X45 the Right Cylinder?
Selecting this 100 mm bore over a smaller 80 mm variant steps up the bidirectional force from 2268 N to 3681 N at 0.5 MPa, making it suitable for heavier symmetric transfer tasks. The double-rod layout is specifically chosen over a single-rod SAI when the application demands anti-rotation guidance, dual-side load driving, or rear-rod position sensing. The 25 mm rod thickness and M20x1.5 thread provide robust side-load capacity, while the PT tapered port threads ensure a tight pneumatic seal.
For ISO 15552 drop-in replacement, match the 100 mm bore, 45 mm stroke, PT G1/2 port, and the appropriate mounting accessory from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this double-rod variant. As the stroke is under 300 mm, external guide support is less critical, but always verify side-load limits for your specific payload.

- ✓ 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 SAID100X45 FAQ
The SAID100X45 provides equal force in both extend and retract directions due to its double-rod design. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes, the SAID100X45 is dimensionally interchangeable per ISO 15552. You can drop-in replace other ISO 15552 double-rod cylinders by matching the 100mm bore, 45mm stroke, G1/2 port, and the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
