About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-40S
The AirTAC SAIJ200X40-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5MPa. With a nominal 40mm stroke and a 40mm adjustment range, it provides a highly adaptable 0 to 40mm usable travel window. This built-in adjustability allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops.
It features a robust 40mm carbon steel rod and a G3/4 PT tapered port to handle high flow requirements. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The rear screw acts purely as a travel stop to set deceleration and end limits, meaning it will not hold the load without live air pressure.

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 SAIJ200X40-40S Is Used
Machine Changeover
Quickly readjusts the retract end-stop during product size changes on the line, saving setup time without replacing the cylinder.
High-Force End Stops
Handles massive loads in automated heavy machinery, using the rear adjuster to set safe deceleration limits for short-stroke movements.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-40S the Right Cylinder?
Choose this 200mm bore when you need extreme force up to 15708N at 0.5MPa, stepping up significantly from the 160mm bore which provides 10053N. The adjustable 0-40mm travel window is ideal for short-stroke clamping or pressing applications where exact end-position tuning is critical during machine setup. If your application requires true load holding without live air, consider the SAIL air-released lock or BSAI clamp-lock cylinders instead of relying on the rear stopper.
This SAIJ200X40-40-S is dimensionally interchangeable per ISO 15552 standards. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). It operates at speeds of 30-500mm/s. Because the stroke is under 300mm, side-load concerns are minimized, but the heavy 40mm rod thread handles high stress well.
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 SAIJ200X40-40S FAQ
The rear adjuster screw allows you to trim the effective travel within a 0 to 40mm usable window from its 40mm nominal stroke. It functions as a mechanical stop to fine-tune the end position and does not lock or hold the load without live air pressure.
