About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-30S
The AirTAC SAIJ200X325-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 325 mm nominal travel by up to 30 mm. This yields a usable end-position window of 295 to 325 mm, enabling rapid machine changeovers without physically swapping the actuator or adding external mechanical stops.
Because this 325 mm stroke is a non-standard made-to-order length exceeding the 1500 mm maximum standard stroke, it is built to exact specifications. The carbon steel rod and M36x2 thread provide high rigidity, though at this extended stroke length an external guide is strongly recommended to manage side loads. This -S variant includes a magnet for position sensing, pairing directly with AirTAC CMSE reed and DMSE solid-state switches mounted into the dual sensor grooves on the extruded aluminum barrel.

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 SAIJ200X325-30S Is Used
Heavy Pressing Operations
Ideal for high-force pressing tasks requiring exact end-position tuning, using the 295-325 mm travel window to accommodate varying material thicknesses.
Product Size Changeovers
Enables rapid line adjustments for different product lengths without swapping out the entire actuator, simply by turning the rear stopper screw.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-30S the Right Cylinder?
Selecting this 200 mm bore actuator makes sense when your application demands very high thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N, which may be insufficient for heavy pressing or lifting. The adjustable rear stopper is chosen over a fixed-stroke SAI cylinder when you need fine end-position tuning at commissioning or when accommodating slight product size variations on the line. It uses a PT tapered G3/4 port and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
If your machine requires the load to be held in place without live air pressure, note that this rear adjuster functions strictly as a travel stop, not a lock. For true load-holding, you would need to integrate an external pilot-operated check valve or select a different AirTAC series like the SAIL (pneumatic lock) or BSAI (clamp-lock). To replace this ISO 15552 cylinder, match the 200 mm bore, 325 mm stroke, 30 mm adjustment, PT port, mounting style, and the -S magnet requirement.

- ✓ 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 SAIJ200X325-30S FAQ
It can achieve a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 325 mm nominal stroke by up to 30 mm, creating a usable travel window of 295 to 325 mm. This stopper decelerates the end of travel but does not lock the load without live air pressure.
