About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-30
The AirTAC SAIJ200X90-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. Equipped with a rear adjustment screw, this model allows you to trim the nominal 90 mm stroke back by up to 30 mm, creating a precise 60-90 mm usable travel window without swapping out the cylinder.
This bore features a robust 40 mm carbon steel rod and a G3/4 PT tapered port to accommodate high airflow for rapid actuation. Unlike fixed-stroke SAI cylinders, the SAIJ rear stopper enables on-the-fly adjustments during product changeovers. Note that this adjuster acts purely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider 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 SAIJ200X90-30 Is Used
Heavy Press Tuning
Dial in the exact 60-90 mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stop blocks.
Assembly Line Changeover
Rapidly adjust the rear stopper during product size changeovers to meet new end-position requirements on the fly, minimizing machine downtime.
Large Fixture Positioning
Fine-tune the clamping end-point on large fixtures, utilizing the 2805 N pull force at 0.9 MPa to securely seat heavy components before machining.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-30 the Right Cylinder?
When replacing an ISO 15552 cylinder, match the 200 mm bore, 90 mm stroke, 30 mm adjustment range, G3/4 PT port, and standard carbon steel rod. Because the stroke is under 300 mm, side-load stress is manageable, but the heavy 40 mm rod still requires external guiding for long unsupported loads. The reduced mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
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 SAIJ200X90-30 FAQ
At the maximum 1.0 MPa pressure, it achieves up to 3204 kgf of thrust.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 90 mm nominal stroke by up to 30 mm, providing a usable travel window of 60 to 90 mm. This stopper only sets the travel end and decelerates the load; it does not function as a lock or brake to hold the load without live air pressure.
