About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-10
The AirTAC SAIJ100X30-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 3927N push force at 0.5 MPa and features a 25mm piston rod with an M20x1.5 thread. The integrated external stopper allows you to trim the nominal 30mm stroke back by up to 10mm, creating a 20-30mm usable travel window for precise end-position tuning without swapping hardware.
This adjustable design is ideal for machine setups requiring exact positioning at changeover. The rear screw functions purely as a travel stop and works alongside the variable air cushions at both ends, meaning it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. This model uses a PT tapered port, includes a standard carbon steel rod, and supports AirTAC CMSE reed and DMSE electronic sensors via its dual-side sensor grooves.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-10 Is Used
Short-Stroke Pressing
Delivers 3927N of push force at 0.5 MPa for compact pressing tasks, with a 10mm adjustment window to set the exact crush depth without adding external stopper blocks.
Machine Changeover
Quickly reconfigure the 20-30mm travel end-stop for different product sizes on a packaging line, using the rear adjuster instead of physically swapping the entire cylinder.
End-Position Tuning
Fine-tune the retraction point during commissioning to perfectly align parts, utilizing the built-in stopper screw alongside the dual-end air cushions for smooth deceleration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-10 the Right Cylinder?
Choose this 100mm bore cylinder when an application requires substantial thrust—such as 3927N push at 0.5 MPa—combined with a very short, finely tunable stroke. If your setup needs less force, stepping down to an 80mm bore yields 2513N push, whereas moving up to a 125mm bore provides 6136N push. The SAIJ100X30-10 is selected over a fixed SAI cylinder when you need a variable end-stop to dial in the final position during commissioning.
When replacing an ISO 15552 cylinder, match the 100mm bore, 30mm nominal stroke, 10mm adjustment range, PT G1/2 port, and your required mounting accessory from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 25mm rod handles high side loads well, it is robust for short-stroke pressing, but always verify external guiding if any lateral forces are present.
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 SAIJ100X30-10 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. It can deliver up to 7068N push at 0.9 MPa.
The rear adjuster screw allows you to shorten the 30mm nominal stroke by up to 10mm, creating a 20-30mm usable travel window. This stopper only sets the travel end and does not lock the load without continuous air pressure.
