About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-40
The AirTAC SAIJ100X325-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end-position without adding external stops. It provides a usable travel window of 285-325 mm, letting you dial back the 325 mm nominal stroke by up to 40 mm during machine commissioning.
This unit uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and is built with a standard extruded aluminum barrel featuring sensor grooves on both sides. It connects via a PT tapered G1/2 port and operates at speeds of 30-800 mm/s. The rear adjuster acts strictly as a travel stop to set deceleration and end-points, meaning it will not hold a load without live air pressure.

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 SAIJ100AX325-40 Is Used
Machine Changeover
Dial in the 285-325 mm travel window during product size transitions to set new end-stops rapidly without changing the cylinder.
Variable End-Stop Positioning
Trim the retract stroke by up to 40 mm to accommodate varying package lengths on a conveyor handling system.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-40 the Right Cylinder?
The adjustable stroke is ideal for product-size changeovers on a line, allowing you to shorten the effective travel without physically swapping the cylinder. If your application requires true load-holding without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is not a locking mechanism.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 325 mm stroke, 40 mm adjustment range, PT G1/2 port, and standard mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the stroke is 325 mm, ensure you use an external guide to prevent excessive side-loading on the 25 mm rod during extended travel.
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 SAIJ100AX325-40 FAQ
At 0.9 MPa, the push force increases to 7068 N.
A rear external screw stopper lets you shorten the 325 mm nominal stroke by up to 40 mm, creating a usable travel window of 285-325 mm. It acts as a travel stop for end-position tuning, not as a load-holding lock.
