About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-20S
The AirTAC SAIJ200X800-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 780 and 800 mm during commissioning. It includes a standard carbon steel rod and a -S magnet for position feedback.
The rear adjuster acts purely as a mechanical stop to set the exact retract end-position, meaning it does not hold the load without live air pressure. For load-holding without continuous supply, you would need an external rod lock or a related AirTAC type like SAIL or BSAI. This extruded aluminum profile cylinder supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200X800-20S Is Used
Heavy Machinery Setup
Dial in the 780-800 mm travel window during heavy equipment commissioning to achieve precise end-position alignment without machining external stoppers.
Product Size Changeover
Quickly adapt automated lines to varying product dimensions by adjusting the rear stopper up to 20 mm, avoiding the need to swap out the entire cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-20S the Right Cylinder?
If you need less force, stepping down to a 160 mm bore yields 10053 N at the same pressure. The adjustable stroke is ideal for product changeovers on a line, letting you dial in the 780-800 mm travel window via the rear screw rather than adding external stops. Because the nominal stroke is 800 mm, an external guide is highly recommended to manage side-load stresses on the 40 mm rod.
This SAIJ200X800-20-S configuration features PT tapered port threads (G3/4), a standard carbon steel rod, and a -S magnet compatible with CMSE reed and DMSE electronic sensors. It is dimensionally interchangeable per ISO 15552 mounting-interface dimensions. The SAIJ mounting options omit FB, CA, CB, and CR, sticking to the standard subset.
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 SAIJ200X800-20S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 780 to 800 mm. The adjuster functions as a travel stop for end-position tuning and does not lock or hold the load without live air pressure.
