About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-40S
The AirTAC SAIJ100X150-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from the 150 mm nominal stroke to a 110 mm minimum. This creates a 110-150 mm usable window, letting you dial in the exact end position during commissioning without swapping out the barrel or adding external stops. It delivers a push force of 3927 N at 0.5 MPa, scaling up to 7068 N at 0.9 MPa.
This specific configuration ships with a SUS420J2 stainless steel rod for improved corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides standard ISO 15552 mounting interchangeability, while the G1/2 port handles the necessary airflow for its 30-800 mm/s speed range.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-40S Is Used
Machine Setup Tuning
Dial in the exact 110-150 mm end position during initial commissioning to perfectly meet a workpiece without machining custom spacers.
Product Changeover
Quickly adjust the retract stop on a packaging line when switching to a different carton size, using the 40 mm trim range to adapt the stroke.
Variable End-Stop Forming
Set precise bottoming positions for pressing or forming operations where the material thickness requires slight positional adjustments between batches.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-40S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 2513 N push force at 0.5 MPa) is insufficient for your load, but you want to avoid the heavier 125 mm option. The 40 mm adjustment range is ideal for product changeovers on a line where the end-stop needs slight tuning between runs. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 150 mm stroke, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2, omitting FB/CA/CB/CR). Because the 150 mm stroke is under the 300 mm threshold, side-loading is less critical, but the 25 mm rod and M20x1.5 thread still handle moderate side loads well if properly guided.
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 SAIJ100AX150-40S 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 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that shortens the retract travel. For this SAIJ100X150-40-S model, it creates an adjustable usable travel window of 110 to 150 mm, allowing fine-tuning of the end position without replacing the cylinder.
