About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-75
The AirTAC SAIJ200X750-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated rear stopper allows you to trim the effective travel, creating a 675-750mm usable window for fine-tuning the retract end position during commissioning.
This model features PT tapered port threads (G3/4) and dual-sided sensor grooves for CMSE reed or DMSE electronic switches. The rear adjuster functions strictly as a travel stop to set deceleration points, not as a locking mechanism. For load-holding without live air pressure, an external rod lock or related SAIL series is required.

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 SAIJ200X750-75 Is Used
Heavy Press Tuning
Dial in the exact 675-750mm end-of-stroke position on large metalforming presses during setup, avoiding the need to machine custom external spacers.
Product Changeover
Quickly adapt automated heavy-duty machinery for different product lengths by turning the rear adjuster screw instead of replacing the entire cylinder.
Long-Stroke Alignment
Fine-tune the retract position on 750mm stroke material handling equipment to perfectly align large workpieces without adding physical stop blocks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-75 the Right Cylinder?
Choose this 200mm bore cylinder when your application demands high thrust (up to 3204 kgf at 1.0 MPa) and precise end-position tuning without swapping components. The 75mm adjustment range is ideal for accommodating product changeovers on large machinery.
When replacing an ISO 15552 cylinder, match the 200mm bore, 750mm stroke, 75mm adjustment, PT G3/4 ports, and the required mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 750mm stroke is long, the 40mm rod will still need an external guide to prevent excessive side-loading damage.
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 SAIJ200X750-75 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 750mm stroke by up to 75mm, providing a usable travel window of 675-750mm for precise end-position tuning.
