About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-50
The AirTAC SAIJ200X105-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a massive 15708N push force at 0.5 MPa. It provides a usable travel window of 55-105mm, letting you dial in the exact retract position without swapping out the unit. The extruded aluminum barrel features sensor grooves on both sides, though this specific configuration omits the magnet.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced durability against surface wear and utilizes PT tapered port threads for a robust pneumatic connection. The rear adjuster functions purely as a mechanical stop to set the travel end, meaning it will not hold a load without live air pressure. For load-holding requirements, an external rod lock or the SAIL series is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-50 Is Used
Heavy Press Tuning
Dial in the exact 55-105mm travel window during heavy press setup to accommodate varying material thicknesses without changing cylinders.
Assembly Line Changeover
Rear stopper adjustment allows rapid product-size changeovers on automated lines, setting new end positions directly at the machine.
Variable End-Stop Actuation
Provides a configurable physical stop for heavy-duty ejection or forming processes where the effective stroke must be trimmed per batch.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-50 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires extreme thrust that a smaller neighbour cannot provide, such as stepping down to a 160mm bore which yields 10053N push force at 0.5 MPa. The adjustable 55-105mm window is highly beneficial for machine changeovers, allowing operators to fine-tune the end position on the fly rather than adding external stops or ordering a fixed-stroke SAI cylinder. Because the stroke is relatively short at 105mm, side-load stress on the 40mm rod is minimized, but an external guide remains good practice for heavy loads.
To match this exact ISO 15552 interchangeable replacement, specify a 200mm bore, 105mm stroke, 50mm adjustment range, PT port thread, and no magnet. The available mounting set is restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some standard cylinders.
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 SAIJ200AX105-50 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can deliver a maximum of 3204 kgf at 1.0 MPa.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from the 105mm nominal stroke down to 55mm. This adjuster sets the end position but does not lock the load; live air pressure is still required to hold position.
