About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X400-10
The AirTAC SAIJ100X400-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 390 to 400 mm usable travel window, allowing you to dial in the retract end-position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
In the 100 mm bore class, this actuator generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, peaking at 801 kgf at 1.0 MPa. It uses a G1/2 port and a 25 mm carbon steel rod with an M20x1.5 thread. The 400 mm stroke length means an external guide is recommended to prevent excessive side-loading on the piston rod.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X400-10 Is Used
Product Changeover
Fine-tune the 390-400 mm end position on the fly to accommodate different package lengths without changing out the cylinder.
Machine Setup
Dial in the exact retract stop during commissioning to perfect tooling alignment and clearances before locking down the run.
Variable End Stops
Adjust the travel end for diverter arms or pushers on a packaging line to handle varying product dimensions efficiently.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X400-10 the Right Cylinder?
Select this 100 mm bore when a 80 mm bore (2513 N push @ 0.5 MPa) lacks the thrust for your tooling, but you want to avoid the mass of a 125 mm unit. An adjustable stroke is ideal for product-size changeovers on a line, letting you fine-tune the end stop in seconds rather than physically swapping a fixed-stroke SAI cylinder.
Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, neither component will hold a load without live air pressure. For drop prevention or position holding without continuous pressure, specify a SAIL air-released lock, a BSAI clamp-lock, or an external rod lock. This model uses a PT tapered port thread and the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100X400-10 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At its maximum 1.0 MPa pressure, it delivers up to 801 kgf of thrust.
The rear adjuster screw lets you shorten the 400 mm nominal stroke by up to 10 mm, creating a 390 to 400 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not hold the load without live air pressure.
