About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-100S
The AirTAC SAIJ200X500-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, a standard carbon steel rod, and a magnetic piston for CMSE / DMSE sensors. The integrated rear stopper allows you to dial back the 500mm nominal stroke by up to 100mm, creating a precise 400-500mm usable travel window for exact end-position tuning during commissioning.
Because the adjuster acts solely as a mechanical stop and works in tandem with the 50mm variable air cushions at both ends, it decelerates the load but does not hold it without live air pressure. The extruded aluminum barrel features sensor grooves on both sides, and the robust M36x2 rod thread handles high side-load stresses. Mounting options include the SAIJ subset 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 SAIJ200X500-100S Is Used
Heavy Press Tuning
Dial in the exact 400-500mm travel window during heavy press commissioning to accommodate material thickness variations without swapping out the actuator.
Pallet Positioning
Adjust the rear stopper on the fly to handle different pallet sizes on a heavy-duty conveyor line, ensuring precise end-stop placement.
Large Assembly Jigs
Fine-tune the end position of large assembly jigs during product changeover, using the 100mm adjustment range to adapt to new fixture dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-100S the Right Cylinder?
Choose this 200mm adjustable-stroke actuator when an application requires heavy thrust—like 15708N at 0.5 MPa—and variable end-stops for product changeovers, rather than a fixed-stroke SAI cylinder. To replace this ISO 15552 cylinder, match the 200mm bore, 500mm stroke, 100mm adjustment range, PT G3/4 port thread, carbon steel rod, and the -S magnet requirement.
For any 500mm stroke, the extended travel creates a high risk of rod deflection and side-loading. Even with the substantial 40mm rod diameter and M36x2 thread, you must use an external guide to prevent premature seal wear. Additionally, because the rear adjuster is a travel stop and not a lock, load-holding without live pressure requires an external rod lock, a pilot-operated check valve, or switching to an AirTAC SAIL or BSAI 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 SAIJ200X500-100S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective travel from the 500mm nominal stroke down to as little as 400mm. This provides a 400-500mm usable travel window for fine-tuning end positions at commissioning without needing external stops.
