About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-75S
The AirTAC SAIJ200X75-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster.
This bore uses a robust 40mm carbon steel rod and G3/4 PT tapered ports to handle high flow demands. It includes a -S magnet for position sensing and is designed to work seamlessly with AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves.

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 SAIJ200X75-75S Is Used
Heavy Press Fine-Tuning
Dial in the exact 0-75mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stopper hardware.
Product Size Changeovers
Quickly adjust the rear stopper on automated lines when switching between product sizes, utilizing the full 75mm trim range to set new end positions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-75S the Right Cylinder?
Select this 200mm bore model when an application requires extreme thrust that smaller bores cannot provide, such as heavy pressing or large gate manipulation. The 75mm adjustment range is ideal for product changeovers, letting you fine-tune the end stop at commissioning rather than swapping a fixed-stroke SAI cylinder or adding external stops.
Because the stroke is under 300mm, side-load risks are lower, though the heavy rod still requires an external guide for lateral loads. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ cannot hold a load without live air. For fail-safe load holding, select the SAIL or BSAI series instead. To match ISO 15552 dimensions, use a 200mm bore, 75mm stroke, 75mm adjustment, G3/4 PT ports, and a -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 SAIJ200X75-75S FAQ
It can reach up to 3204 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw acts as an external stopper that lets you shorten the effective stroke by up to 75mm. Since the nominal stroke is 75mm, you can trim the usable travel window anywhere from 0 to 75mm without replacing the cylinder.
