About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-75S
The AirTAC SAIJ200X80-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 80 mm travel by up to 75 mm. This creates a highly flexible 5-80 mm usable travel window, perfect for dialing in exact end positions during machine commissioning without swapping out the physical cylinder.
This adjustable-stroke design relies on a rear mechanical stopper to set the retract end position, meaning it is not a locking device and cannot hold a load without live air pressure. For load-holding applications without continuous air, consider the SAIL or BSAI series. This -S variant includes a standard magnet for position sensing and features a carbon steel piston rod with an M36x2 thread. It uses PT tapered ports and operates at speeds between 30 and 500 mm/s.

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 SAIJ200X80-75S Is Used
Heavy Press Fine-Tuning
Dial in the exact 5-80 mm retract position for heavy-duty pressing tasks, ensuring optimal contact force without needing to machine custom spacers.
Product Changeover
Quickly adjust the end-stop during production line changeovers to accommodate different product sizes, minimizing machine downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-75S the Right Cylinder?
Choose this 200 mm bore model when your application requires extreme force—up to 15708 N at just 0.5 MPa—combined with a highly variable stroke window. The SAIJ200X80-75-S is specifically selected when you need to fine-tune the retract end-stop on the fly, such as during product changeovers, rather than relying on a fixed-stroke SAI cylinder. Because the 80 mm stroke is relatively short for this large bore, side-loading is less of a concern than with longer strokes, but an external guide is still recommended for heavy loads. To replace an ISO 15552 cylinder, match the 200 mm bore, 80 mm stroke, 75 mm adjustment, PT port, and -S magnet.
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 SAIJ200X80-75S FAQ
If operating at 0.7 MPa, the push force increases to 21991 N.
The nominal stroke is 80 mm, but the rear adjuster allows you to shorten the stroke by up to 75 mm. This results in a usable travel window of 5 to 80 mm, which can be fine-tuned during commissioning.
