About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-10
It integrates a rear mechanical stopper that allows you to fine-tune the effective travel down from the 800mm nominal stroke, creating a precise 790-800mm usable window. This built-in adjustability eliminates the need to physically swap out the barrel or add external stopper blocks during machine commissioning.
Equipped with a robust 40mm carbon steel rod and an M36x2 thread, this 200mm bore unit handles significant side loads, though an 800mm stroke still necessitates an external guide to prevent rod bending. The extruded aluminum barrel features sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Fluid supply is routed through a G3/4 PT port, and the unit omits the FB, CA, CB, and CR mounting interfaces, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

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 SAIJ200X800-10 Is Used
Heavy Press Tuning
Dial in the exact 790-800mm end-stop during setup to accommodate varying material thicknesses in large-scale metal forming and heavy press operations.
Automated Assembly Changeover
Quickly adjust the retract position on automated assembly lines when switching between product sizes, avoiding the downtime of physically swapping cylinders.
Large Conveyor Positioning
Fine-tune the actuation end-point on heavy-duty conveyor sorting gates to ensure precise alignment without adding external mechanical stopper blocks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-10 the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application requires extreme thrust that smaller bores cannot provide; for context, dropping down to a 160mm bore reduces your 0.5 MPa push force to 10053N. You would specifically choose this adjustable SAIJ over a fixed-stroke SAI when you need a variable end-stop to dial in the exact retract position of a heavy load during product changeovers. Because the 800mm stroke exceeds the 300mm threshold, you must incorporate an external linear guide to manage side-loading and prevent rod damage.
When matching this ISO 15552 cylinder as a replacement, verify the 200mm bore, 800mm stroke, 10mm adjustment range, PT G3/4 port thread, and the specific mounting bracket. Note that the rear adjuster functions strictly as a travel stop and deceleration aid, not as a locking mechanism. If your machinery requires true load-holding without continuous live air pressure, you must integrate an external pilot-operated check valve or switch to an AirTAC SAIL or BSAI series cylinder.

- ✓ 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 SAIJ200X800-10 FAQ
If operating at 0.9 MPa, the push force increases to 28274N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 800mm down to 790mm, giving you a 790-800mm usable window. It functions only as a travel stop and does not lock the load without continuous live air pressure.
