About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-30
The AirTAC SAIJ200X750-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 720-750 mm usable travel window, allowing you to dial back the 750 mm nominal stroke by up to 30 mm during commissioning.
This large-bore pneumatic actuator uses a PT tapered port (G3/4) and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a travel stop to set end positions accurately and is not a locking mechanism.

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 SAIJ200X750-30 Is Used
Heavy Machinery Positioning
Moves massive fixtures or platens on large assembly lines, utilizing the 30 mm rear adjustment to perfectly dial in the final resting position without re-engineering the machine base.
Product Changeover Stops
Accommodates varying part sizes on a single conveyor system by adjusting the effective travel end-point between 720 and 750 mm, enabling rapid line changeovers.
Large Press Tuning
Fine-tunes the retract stroke on heavy stamping or forming equipment during setup, ensuring precise end-position alignment while handling the massive 3204 kgf maximum load capacity.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-30 the Right Cylinder?
Choose this 200 mm bore model when an application requires extreme thrust up to 15708 N at 0.5 MPa, or a maximum of 3204 kgf at 1.0 MPa. The SAIJ200X750-30 is selected over a fixed SAI cylinder when you need a variable end-stop to fine-tune the retract position on product changeovers without swapping the actuator.
Because the nominal stroke is 750 mm, the long unsupported rod is susceptible to side-loading damage; an external guide rail is highly recommended to prevent premature seal wear. For applications requiring the load to be held in place without continuous live air pressure, note that the rear adjuster and air cushions will not function as a brake. In those cases, consider an AirTAC SAIL pilot-lock cylinder, a BSAI clamp-lock model, or an external rod lock. This profile cylinder is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200X750-30 FAQ
At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from the 750 mm nominal length down to 720 mm. This provides a 720-750 mm usable travel window for fine-tuning the end position at commissioning without adding external stops.
