About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-30S
It features a 100 mm nominal stroke that can be dialed back by up to 30 mm, providing a usable travel window of 70 to 100 mm. This adjustability allows you to fine-tune end positions at commissioning without swapping out the cylinder or adding external stops.
Built with a SUS420J2 stainless steel rod and a -S magnet for CMSE reed and DMSE electronic sensors, it integrates cleanly into existing setups. The extruded aluminum barrel includes sensor grooves on both sides, and the unit omits FB, CA, CB, and CR mounts, utilizing a precise subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting options.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-30S Is Used
Variable End-Stop Tuning
Dial in the exact 70 to 100 mm travel distance during machine setup to accommodate varying product sizes without external spacers.
Changeover Optimization
Quickly adjust the retract end-position by up to 30 mm during production line changeovers to reduce downtime and avoid cylinder swaps.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-30S the Right Cylinder?
The adjustable stroke is ideal for product changeovers, letting you set a variable end-stop directly at the rear screw instead of machining new spacers. Remember that the rear adjuster functions as a travel stop and deceleration point, not a lock; it will not hold the load without live air. For position holding without pressure, consider SAIL or BSAI cylinders.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 100 mm stroke, 30 mm adjustment, PT tapered ports, and the -S magnet option. Because the stroke is 100 mm, side-load risks are minimal, but always ensure the M20x1.5 rod thread and 25 mm rod diameter are properly aligned with your external guide to prevent binding.
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 SAIJ100AX100-30S FAQ
The maximum thrust is 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from its 100 mm nominal length down to 70 mm. It is a travel stop for fine-tuning, not a load-holding lock.
