About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-30S
The AirTAC SAIJ200X290-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing with 15708N and pulling with 15080N at 0.5 MPa. The integrated -30 mm adjustment mechanism allows you to fine-tune the effective travel window down to 260 mm from the 290 mm nominal stroke. This on-machine tuning is ideal for dialing in exact end positions without swapping hardware.
Equipped with a -S magnet, this carbon-rod unit supports position sensing via CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves. It uses PT G3/4 ports and relies on 50 mm variable air cushions at both ends to decelerate the heavy 40 mm rod. Remember that this rear screw acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding, explore the SAIL or BSAI series.

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 SAIJ200X290-30S Is Used
Heavy Press Fine-Tuning
Dial in the exact 260 to 290 mm travel window during heavy press commissioning to achieve perfect clamping without swapping cylinders.
Product Size Changeovers
Quickly reposition the rear stop on a packaging line to handle different pallet heights using the 30 mm adjustment range.
Sensor-Driven End Stops
Utilize the integrated magnet with DMSE electronic sensors to verify the adjusted end position in automated assembly lines.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-30S the Right Cylinder?
The adjustable-stroke design is chosen over a fixed SAI cylinder when commissioning requires variable end-stops or product changeovers need precise repositioning. Because the 290 mm stroke is substantial, the 40 mm carbon steel rod and M36x2 thread handle high stress, but long unsupported travel demands an external guide to prevent side-load damage.
For a true ISO 15552 dimensional replacement match, verify the 200 mm bore, 290 mm stroke, 30 mm adjustment, PT G3/4 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR. Operating speed is 30-500 mm/s, and the adjuster only sets the travel end—it is not a lock.

- ✓ 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 SAIJ200X290-30S FAQ
The maximum thrust is 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 290 mm nominal stroke by up to 30 mm, creating a 260 to 290 mm usable travel window. It decelerates the end position but does not lock the load without live air.
