About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-40S
The AirTAC SAIJ200X90-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning during commissioning. With a nominal 90 mm stroke and a 40 mm adjustment range, it provides a usable travel window of 50 to 90 mm without requiring external stops or cylinder replacement. It delivers massive thrust, pushing 21991 N at 0.7 MPa and 28274 N at 0.9 MPa, making it suitable for heavy-duty operations.
This model features a carbon steel piston rod and includes a magnet (-S) for compatibility with AirTAC CMSE reed and DMSE electronic sensors, which mount into the dual-side sensor grooves on the extruded aluminum barrel. It uses PT tapered G3/4 ports and operates at speeds between 30 and 500 mm/s. The rear adjuster functions strictly as a travel stop to decelerate the load, not as a lock, so live air pressure must be maintained to hold the load.

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 SAIJ200X90-40S Is Used
Heavy Machinery Positioning
Dial in the exact 50 to 90 mm end-stop for large presses and heavy material handling equipment during setup.
Product Line Changeover
Quickly adjust the retract stroke to accommodate different product sizes on the same ISO 15552 mounting footprint.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-40S the Right Cylinder?
If you need less force, stepping down to the 160 mm bore yields 14074 N at the same pressure, whereas moving up is impossible as this is the largest standard SAIJ size. The adjustable 50-90 mm travel window is ideal for product changeovers or setups requiring variable end stops without swapping cylinders. For holding loads without live air pressure, consider an AirTAC SAIL or BSAI cylinder, or use an external pilot-operated check valve, as the SAIJ adjuster is only a stop. Ensure proper external guidance for the rod to handle side loads effectively.
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 SAIJ200X90-40S FAQ
The nominal stroke is 90 mm, but the 40 mm rear adjuster allows you to fine-tune the effective travel anywhere between 50 mm and 90 mm.
