About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-30S
The AirTAC SAIJ100X150-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 120-150 mm usable travel window from its 150 mm nominal stroke, allowing you to dial back the retract end position by up to 30 mm during commissioning. It delivers 3927 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod for enhanced corrosion resistance.
This model includes a magnet for position sensing with CMSE reed and DMSE electronic switches. The extruded aluminum barrel integrates sensor grooves on both sides. It uses a G1/2 port and omits the FB, CA, CB, and CR mounts, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-30S Is Used
Machine Changeover
Dial in the 120-150 mm retract position during format changes without physically swapping cylinders or reengineering fixed stops.
End-Position Tuning
Fine-tune the final resting position of a heavy press tool at commissioning, using the 30 mm rear screw to absorb mechanical tolerance.
Variable End Stops
Set distinct retract endpoints on an automated line to handle multiple product sizes using the same 3927 N thrust cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-30S the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder (2513 N push at 0.5 MPa) is insufficient but a 125 mm bore is too large. The adjustable 30 mm travel window is ideal for product changeovers, letting you fine-tune the retract stop without adding external stops or swapping the cylinder. For strokes of 300 mm or more, you must use an external guide to prevent side-load wear, though this 150 mm stroke is well within safe limits.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 150 mm stroke, 30 mm adjustment, PT tapered port threads, and the -S magnet. Note that the rear adjuster acts only as a travel stop, not a lock; it will not hold the load without live air. For true load-holding, consider the SAIL or BSAI series instead.
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 SAIJ100AX150-30S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 150 mm nominal stroke by up to 30 mm, creating a 120-150 mm usable travel window. It acts as a mechanical stop to tune the end position and does not lock the load without live air pressure.
