About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X70-10S
The AirTAC SAIJ100X70-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. It features a 100mm bore and a 70mm nominal stroke that can be dialed back by up to 10mm, providing a 60-70mm usable travel window for exact end-position tuning. In this -S configuration, the extruded aluminum barrel includes a magnet ready for CMSE reed and DMSE electronic sensors.
Delivering 3927N of push force and 3681N of pull force at 0.5MPa, it uses a G1/2 port and a robust 25mm carbon steel rod with an M20x1.5 thread. The rear stopper allows quick commissioning changes without swapping the cylinder, while the shared mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X70-10S Is Used
Press Stroke Calibration
Dial in the exact 60-70mm travel window during machine commissioning to ensure a press bottoms out perfectly without mechanical interference.
Product Changeover
Quickly adjust the end-stop by up to 10mm when switching between product sizes on a packaging line, avoiding cylinder swaps.
Fixture Clamping
Leverage the 3927N push force to secure heavy workpieces, using the fine adjustment to prevent over-travel and crush damage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X70-10S the Right Cylinder?
Choose this 100mm bore actuator when your application requires substantial thrust—3927N at 0.5MPa—along with a short, fine-tuned travel window. If your setup needs less force, stepping down to an 80mm bore yields 2513N of push force. The 10mm adjustment range is ideal for dialing in a precise end-stop during machine setup or product changeover, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder.
For replacement, match the 100mm bore, 70mm stroke, 10mm adjustment, PT tapered port thread, and -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an AirTAC SAIL or BSAI cylinder. Because the stroke is under 300mm, side-load concerns are minimal, but the 25mm rod thread handles standard loads well.
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 SAIJ100 Adjustable Cylinder SAIJ100X70-10S FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9MPa, the push force increases to 7068N.
The rear adjuster acts as a mechanical stop that lets you shorten the 70mm nominal stroke by up to 10mm, creating a 60-70mm usable travel window. It is a travel stop, not a lock, and does not hold the load without live air pressure.
