About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-20S
The AirTAC SAIJ200X750-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suited for heavy-duty industrial positioning. The extruded aluminum barrel features sensor grooves on both sides for straightforward switch installation.
This specific SKU provides a 750 mm nominal stroke that can be dialed back by up to 20 mm, creating a 730-750 mm usable travel window. This built-in adjuster acts as a mechanical stop at the retract end, allowing you to fine-tune the end position during commissioning without adding external stops. It includes a standard carbon steel rod and a magnet for CMSE reed and DMSE electronic sensors.

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 SAIJ200X750-20S Is Used
Heavy Press Tuning
Dial in the exact 730-750 mm retract position during heavy press commissioning without swapping cylinders or adding external mechanical stops.
Large Mold Changeover
Adjust the end-stop on the fly to accommodate slight variations in large industrial mold depths during automated production line changeovers.
Long-Stroke Alignment
Fine-tune the retract distance on heavy-duty straightening presses where a 20 mm adjustment window corrects minor mechanical drift.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-20S the Right Cylinder?
The adjustable 730-750 mm travel window is ideal for machinery requiring exact end-position tuning during product changeovers. Because the adjuster is a travel stop and not a locking mechanism, you must maintain live air pressure to hold the load; for fail-safe load holding without air, consider an AirTAC SAIL or BSAI cylinder.
For an ISO 15552 replacement match, specify a 200 mm bore, 750 mm stroke, 20 mm adjustment range, PT tapered port threads, and a magnet (-S) for CMSE/DMSE sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Given the 750 mm stroke, the 40 mm carbon steel rod and M36x2 thread handle high stresses, but an external guide is recommended to prevent side-loading damage on long unsupported travels.
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 SAIJ200X750-20S FAQ
The operational speed range is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the 750 mm nominal stroke by up to 20 mm, providing a 730-750 mm usable travel window. It requires live air to hold position and does not function as a lock.
