About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-10S
The AirTAC SAIJ200X190-10-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial push force of 15708N at 0.5MPa and a maximum of 3204kgf at 1.0MPa. It features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. A PT tapered G3/4 port thread ensures a rigid, leak-free pneumatic connection.
Equipped with a rear stroke adjuster, this model allows you to trim the nominal 190mm stroke back by up to 10mm, creating a precise 180-190mm usable travel window for product changeovers. The extruded aluminum barrel incorporates sensor grooves on both sides, and the variable air cushions at both ends work alongside the rear stopper to decelerate the massive load. Remember that this adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-10S Is Used
Heavy Press Tuning
Dial in the exact end-position for heavy pressing and forming tasks by adjusting the travel within the 180-190mm window to accommodate different material thicknesses.
Machine Changeover
Quickly adapt large-scale automated machinery to new product sizes by turning the rear stopper, avoiding the downtime of physically swapping out a massive cylinder.
High-Force Positioning
Move and position heavy industrial payloads with up to 3204kgf of force, relying on the SUS420J2 stainless rod to withstand harsh manufacturing environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-10S the Right Cylinder?
Selecting this 200mm bore cylinder is ideal when your application requires extreme thrust within a compact 180-190mm adjustable travel window. If you need slightly less force, stepping down to a 160mm bore yields 10053N at 0.5MPa, but the 200mm bore is necessary for heavy pressing or lifting. The rear adjuster is chosen over a fixed-stroke SAI when you need fine end-position tuning at commissioning without bolting on external stops. For load-holding without continuous live air, this plain cylinder is insufficient; you should look at the SAIL (air-released lock) or BSAI (clamp-lock) series instead. To replace an ISO 15552 cylinder, match the 200mm bore, 190mm stroke, 10mm adjustment, PT G3/4 port, and the -S magnet. Because the stroke is under 300mm, side-load stress is manageable, but the 40mm rod diameter still requires an external guide for heavy lateral loads.
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 SAIJ200AX190-10S FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it delivers up to 3204kgf.
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective travel from the 190mm nominal stroke down to a minimum of 180mm. This creates a 180-190mm usable window for fine-tuning the end position without replacing the cylinder.
