About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-40
The AirTAC SAIJ200X750-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. By turning the external stopper screw, you achieve a usable travel window of 710-750mm, allowing precise end-position tuning at commissioning without swapping out the entire actuator.
This 200mm bore actuator features a robust 40mm carbon steel rod and a PT G3/4 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Because it is a profile cylinder, it omits tie-rods, yielding a cleaner exterior. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, meaning it cannot hold loads without live air pressure.

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 SAIJ200X750-40 Is Used
Heavy Press Tuning
Dial in the exact 710-750mm end-of-stroke position during machine setup to accommodate varying workpiece heights without adding external mechanical stops.
Product Changeover
Quickly adjust the retract distance on a heavy pallet stopper when switching the production line to a different package size.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-40 the Right Cylinder?
The adjustable 40mm window is chosen over a fixed-stroke SAI cylinder when you need variable end-stops for product changeovers on a line. To match this ISO 15552 replacement exactly, verify the 750mm stroke, 40mm adjustment, PT G3/4 port, and standard carbon steel rod. Note that this SKU does not include a magnet; add an -S suffix if you require CMSE or DMSE sensor compatibility.
With a 750mm stroke, the 40mm rod will experience significant leverage under side loads. You must use an external guide to prevent binding and premature seal wear. Furthermore, if your process demands true load-holding without continuous air pressure, the rear adjuster here will not suffice; consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ200X750-40 FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 750mm down to 710mm. This creates a 710-750mm usable window, allowing you to fine-tune the end position at commissioning. The screw acts only as a travel stop and does not lock the load.
