About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-40
The AirTAC SAIJ200X80-40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a rear mechanical adjuster that permits precise end-position tuning. With a nominal stroke of 80 mm and a 40 mm adjustment range, you can dial the effective travel down to a 40-80 mm window during commissioning without swapping hardware or adding external stops. This size delivers immense thrust, pushing 15708 N at 0.5 MPa and up to 28274 N at 0.9 MPa.
The bore utilizes a G3/4 port and a robust 40 mm carbon steel rod with an M36x2 thread, providing exceptional resistance against side loads. It features variable air cushions at both ends to manage high kinetic energy, while the extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster functions strictly as a travel stop for position tuning, not as a locking device, and cannot hold a load without continuous 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 SAIJ200X80-40 Is Used
Heavy Press Tuning
Dial in the exact 40-80 mm pressing depth for high-force forming operations, accommodating different material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the end-stop position on a packaging line when switching to a new container size, minimizing machine downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-40 the Right Cylinder?
The adjustable stroke is particularly beneficial in automated assembly lines where product sizes change frequently, allowing operators to fine-tune the 40-80 mm travel window on the fly rather than machining custom spacers. If your machine layout requires a fixed end-of-stroke without any rear protrusion, the standard SAI fixed-stroke series is a better fit.
For ISO 15552 replacement matching, verify the 200 mm bore, 80 mm stroke, 40 mm adjustment range, PT tapered port thread, and standard carbon steel rod. Because this cylinder lacks a magnet, it cannot host CMSE or DMSE sensors; if position feedback is required, you must specify the -S option. Furthermore, while the 40 mm rod handles high stresses, any application utilizing the upper end of the 80 mm stroke should still employ an external guide rail to prevent rod binding. For applications requiring true load holding without live air, consider the SAIL or BSAI series instead of relying on the stopper.
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 SAIJ200X80-40 FAQ
At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 80 mm nominal stroke to any effective length within a 40-80 mm window. It only sets the travel end point and does not lock the load without live air.
