About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-40
The AirTAC SAIJ200X90-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 50 to 90 mm from its 90 mm nominal stroke.
This model features a 40 mm carbon steel piston rod with an M36x2 male thread, paired with 50 mm variable air cushions at both ends to absorb high kinetic energy. The extruded aluminum barrel includes dual-side sensor grooves for direct mounting of CMSE reed or DMSE solid-state switches, while the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits heavy rear pivot options to suit compact high-force frames.

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 SAIJ200X90-40 Is Used
Heavy Press Positioning
Dial in the exact 50-90 mm travel window during machine setup to precisely control heavy metal stamping or press operations without external stopper blocks.
Product Line Changeover
Rapidly adjust the retract end-stop to accommodate varying product sizes on a high-force assembly line, minimizing downtime between production runs.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-40 the Right Cylinder?
The rear stopper screw is invaluable for fine-tuning the retract end-position during commissioning or product-size changeovers without physically swapping the cylinder or adding external stops. Remember that the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold position without live air. For true fail-safe load holding, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIJ200X90-40 FAQ
The rear adjuster screw acts as a mechanical stop that trims the effective travel back by up to 40 mm, giving you an adjustable 50 to 90 mm window. It sets the end position and decelerates the load, but it is not a lock and requires live air to hold position.
If you increase the pressure to 0.7 MPa, the push force rises to 21991 N.
