About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-30
The AirTAC SAIJ200X325-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 295 to 325 mm, allowing you to dial back the nominal stroke by up to 30 mm during commissioning without adding external stops.
This extruded aluminum barrel design includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the end position, working alongside the 50 mm variable air cushions to manage deceleration. It supports a speed range of 30-500 mm/s and accepts a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X325-30 Is Used
Heavy Pressing Setup
Dial in the 295-325 mm travel window to precisely set the pressing depth for large industrial assemblies during commissioning.
Product Changeover
Quickly adjust the retract end-stop to accommodate varying package sizes on a heavy-duty conveyor line without changing hardware.
Variable End-Stop Positioning
Use the rear mechanical stopper to tune the exact end position for heavy material ejection tasks at 0.7 MPa operating pressure.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-30 the Right Cylinder?
An adjustable stroke is highly beneficial for product-size changeovers on a line, letting you fine-tune the retract end without physically swapping the cylinder. Because the 325 mm stroke is substantial, always use an external guide to prevent side-load damage to the 40 mm rod.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 325 mm nominal stroke, 30 mm adjustment range, G3/4 PT port, and the specific mounting interface. Note that this SAIJ variant omits the FB, CA, CB, and CR mounting brackets. The rear screw is a travel stop, not a lock; for load-holding without live air pressure, consider the AirTAC SAIL or BSAI series.
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 SAIJ200 Adjustable Cylinder SAIJ200X325-30 FAQ
At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 325 mm down to 295 mm. It functions as a mechanical stop to fine-tune the end position at commissioning, but it does not lock the load without live air pressure.
