About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-50S
The AirTAC SAIJ200X950-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing with 15708N and pulling 15080N at 0.5 MPa, making it suitable for heavy-duty positioning. The integrated magnet (-S) allows seamless position feedback via CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
This specific SKU features a 950mm nominal stroke that can be dialed back by up to 50mm, creating a 900-950mm usable travel window. This built-in adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load. For applications requiring load holding without live air pressure, an external pilot-operated check valve or a dedicated BSAI clamp-lock cylinder is required.

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 SAIJ200X950-50S Is Used
Long-Stroke Changeover
The 50mm rear adjuster allows operators to dial in the 900-950mm travel window during machine setup or product size changes without external stops.
Automated Assembly Lines
Integrates DMSE electronic sensors via the -S magnet to confirm full retraction on long-stroke automated machinery and material transfer systems.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-50S the Right Cylinder?
The adjustable 900-950mm window is ideal for product changeovers on long-stroke machinery, allowing you to set variable end-stops without physically swapping the cylinder or adding external stopper blocks. A standard fixed-stroke SAI cylinder lacks this fine-tuning flexibility.
When configuring your ISO 15552 replacement, verify the 950mm stroke, 50mm adjustment, PT tapered port threads, and carbon steel rod material. Because the 950mm stroke is long and the rod is heavy, an external guide is strongly recommended to prevent excessive side-loading on the piston. This model supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets.
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 SAIJ200X950-50S FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from 950mm down to 900mm. This enables fine-tuning of the end position during commissioning without needing to swap the cylinder.
