About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-100S
The AirTAC SAIJ200X325-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708 N at 0.5 MPa. With a nominal 325 mm stroke and a 100 mm adjustment range, it provides a usable travel window of 225-325 mm. This allows you to fine-tune the retract end position precisely at commissioning without swapping the barrel or adding external stops.
It features a robust 40 mm carbon steel rod and M36x2 thread, built to handle high side loads, though the 325 mm travel requires an external guide to prevent rod deflection. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold the load without live air.

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 SAIJ200X325-100S Is Used
Heavy Pressing
Dial in the exact 225-325 mm end position for heavy pressing tasks during initial machine commissioning.
Product Changeover
Quickly adjust the retract stop for varying product sizes on the line without changing the cylinder.
Variable End Stops
Use the 100 mm trim window to tune the travel end and optimize cycle timing for large assemblies.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-100S the Right Cylinder?
Choose this 200 mm bore when the 160 mm class (14074 N at 0.5 MPa) is insufficient for your heavy-duty push loads. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. For load-holding without live air pressure, this cylinder will not suffice; consider the SAIL or BSAI series instead.
This model is dimensionally interchangeable per ISO 15552. It uses a PT tapered G3/4 port, standard carbon steel rod, and includes a magnet (-S) for CMSE and DMSE sensors. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ200X325-100S FAQ
The rear adjuster allows you to shorten the effective travel from 325 mm down to 225 mm, creating a 100 mm adjustable window for fine-tuning the end position.
