About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-20
The AirTAC SAIJ200X1000-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 980 to 1000 mm, letting you dial back the stroke by up to 20 mm during machine commissioning without adding external stops. Built with a 200 mm bore, it generates a substantial 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it ideal for heavy-duty positioning tasks.
This extruded aluminum barrel design includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state sensors. The piston rod is crafted from SUS420J2 stainless steel for enhanced durability against corrosion, and the PT tapered port threads ensure a robust, leak-free pneumatic connection. Operating at speeds up to 500 mm/s, it relies on adjustable air cushions at both ends to decelerate the massive load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-20 Is Used
Heavy Assembly Pressing
Provides up to 15708 N of thrust at 0.5 MPa for seating large industrial components, with the 20 mm rear adjuster allowing precise tuning of the pressing depth during setup.
Oversized Payload Transfer
Moves heavy pallets or structural frames along a 1000 mm stroke, using the adjustable end-stop to accommodate varying product lengths without repositioning the cylinder.
Automated Line Changeover
Speeds up product-size changeovers on automated lines by letting operators dial in the 980-1000 mm travel window directly at the rear stopper instead of machining new hard stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-20 the Right Cylinder?
Selecting this 200 mm bore model makes sense when your application requires extreme thrust, such as pressing or lifting heavy assemblies, and you need the 980-1000 mm adjustable window to perfectly dial in the final end-stop without swapping cylinders. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which might save space and air consumption. Because this unit features a 1000 mm stroke, the 40 mm diameter rod and M36x2 thread provide excellent rigidity, but an external guide is strongly recommended to prevent excessive side-loading on the long unsupported travel.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 1000 mm stroke, 20 mm adjustment range, PT port threads, and the desired mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Remember that the rear adjuster acts purely as a travel stop and the air cushions only manage deceleration; neither will hold the load if air pressure drops. For true load-holding without live air pressure, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock 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 SAIJ200AX1000-20 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 20 mm, creating a 980 to 1000 mm usable travel window. It allows fine-tuning of the retract end position during commissioning but does not lock the load without live air pressure.
