About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-40
The AirTAC SAIJ200X290-40 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the rear stopper screw, you can trim the effective travel down by up to 40 mm, creating a precise 250-290 mm usable stroke window without swapping out the entire actuator.
This 200 mm bore actuator features a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to absorb heavy kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches if position feedback is required later. Fluid must be filtered to 40 um, operating within a 0.15-1.0 MPa pressure range and a -20 to +70 C temperature environment.

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 SAIJ200X290-40 Is Used
Heavy Press Tuning
Dial in the exact 250-290 mm end position for high-tonnage pressing operations during setup, ensuring perfect contact without replacing the actuator.
Product Changeover
Quickly adjust the rear stopper by up to 40 mm on a production line when switching between product sizes, minimizing machine downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-40 the Right Cylinder?
The adjustable 250-290 mm travel window is ideal for fine-tuning end positions during machine commissioning or product changeovers, eliminating the need to bolt on external stops. Because the stroke is 290 mm, the heavy load should be externally guided to prevent excessive side-loading on the 40 mm rod. For a direct ISO 15552 replacement, match the 200 mm bore, 290 mm stroke, 40 mm adjustment, PT tapered ports, and standard carbon steel rod.
The rear adjuster functions strictly as a travel stop, not a locking device. It cannot hold a load without continuous live air pressure. If your application requires true load-holding in the event of air loss, consider the AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) series instead. Mounting options for this profile cylinder include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200X290-40 FAQ
At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 290 mm nominal stroke by up to 40 mm. This creates a usable travel window of 250-290 mm for fine-tuning end positions without adding external stops.
