About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-10S
The AirTAC SAIJ200X950-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position by up to 10 mm. This yields a usable travel window of 940-950 mm, letting you dial in the exact end-of-stroke position at commissioning without adding external stops.
It features a carbon steel piston rod and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and because this is the -S variant, it includes a magnet ready for AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear adjuster acts purely as a mechanical stop to set the travel end; it does 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 SAIJ200X950-10S Is Used
Heavy Press Tuning
Dial in the exact 940-950 mm end position during heavy press commissioning without installing external mechanical stops.
Product Changeover
Quickly adjust the retract stroke by up to 10 mm on automated assembly lines when shifting between slightly different product sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-10S the Right Cylinder?
Choose this 200 mm bore cylinder when you need extreme thrust capacity—up to 15708 N at 0.5 MPa—and a highly specific 940-950 mm travel window. The adjustable stroke is ideal for machine setup and product changeovers, allowing you to trim the 950 mm nominal stroke by up to 10 mm rather than swapping to a different fixed-stroke SAI cylinder.
Because the stroke is 950 mm, the 40 mm diameter carbon steel rod will experience leverage forces under side loading; an external guide is strongly recommended to prevent rod wear. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the rear adjuster and air cushions only decelerate the travel end; for true load-holding without live pressure, use a SAIL or BSAI cylinder instead.

- ✓ 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 SAIJ200X950-10S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 950 mm nominal stroke by up to 10 mm, providing a usable travel window of 940-950 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
