About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-30
The AirTAC SAIJ200X40-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion control. An integrated rear adjusting screw allows you to dial back the travel, creating a precise 10 to 40mm usable stroke window for exact end-position tuning during commissioning.
This adjustable design eliminates the need to swap cylinders or bolt on external stops when adapting to slight product variations. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE and DMSE switches. Featuring a carbon steel rod and PT tapered port threads, this profile cylinder omits rear pivot mountings, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

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 SAIJ200X40-30 Is Used
Product Changeover
Quickly adapt the 10-40mm stroke window on the fly to accommodate varying workpiece heights on a production line.
End-Stop Calibration
Ideal for heavy machinery setup where the rear stopper screw fine-tunes the retract position perfectly during initial commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-30 the Right Cylinder?
Selecting this 200mm bore model is ideal when your application requires massive push force, delivering 15708N at just 0.5MPa. If your setup needs less force, stepping down to a 160mm bore provides 10053N, but the 200mm is unmatched for high-tonnage pressing. The 30mm adjustment range is chosen when you need variable end-stops for product changeovers, offering a 10-40mm travel window that a fixed-stroke SAI cylinder cannot provide.
For stroke lengths of 300mm or more, external guides are mandatory to handle side loads, but this 40mm short-stroke unit relies on its 40mm carbon steel rod and M36x2 thread for inherent stability. Remember that the rear adjuster acts purely as a travel stop, not a lock; the SAIJ does not hold loads without live air. For load-holding without pressure, consider an external rod lock or the AirTAC SAIL or BSAI series. To ensure exact ISO 15552 dimensional interchangeability, verify the 200mm bore, 40mm stroke, PT port threads, and mounting style.
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 SAIJ200X40-30 FAQ
It can deliver up to 3204 kgf at its maximum 1.0MPa pressure rating.
The rear adjuster screw acts as a mechanical stop that can shorten the 40mm nominal stroke by up to 30mm. This creates a usable travel window of 10 to 40mm, allowing you to fine-tune the end position at commissioning without replacing the cylinder.
