About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-10S
The AirTAC SAIJ200X800-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a precise 790-800 mm usable travel window. Delivering 15708 N of push force at 0.5 MPa, it handles heavy-duty positioning with ease. The barrel is extruded aluminum with sensor grooves on both sides, and the rod is constructed from SUS420J2 stainless steel for enhanced corrosion resistance.
This model includes a -S magnet for position feedback, seamlessly supporting AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning without adding external stops; it does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-10S Is Used
Heavy Press Positioning
Dial in the exact 790-800 mm retract stop during heavy press setup to accommodate different die heights without changing the cylinder.
Product Changeover
Fine-tune the end position on automated assembly lines when switching product sizes, using the rear adjuster to shift the stroke window by up to 10 mm.
Large Material Handling
Move heavy payloads with 15708 N of thrust while using the -S magnet and DMSE sensors to confirm end-of-stroke arrival in large automated lines.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-10S the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires the maximum 15708 N thrust at 0.5 MPa alongside precise end-position tuning. The 10 mm adjustment window is ideal for dialing in exact retract positions during machine setup or product changeover, avoiding the need to physically swap a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, this cylinder is insufficient; you should specify an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock instead.
Because this model features an 800 mm stroke, the 40 mm diameter SUS420J2 rod and M36x2 thread provide robust support, but an external guide is strictly required to prevent excessive side-loading and binding over long travel distances. To replace an ISO 15552 cylinder, match the 200 mm bore, 800 mm stroke, 10 mm adjustment, PT G3/4 port, and the -S magnet requirement.
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 SAIJ200AX800-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 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 mechanical stopper allows you to shorten the nominal 800 mm stroke by up to 10 mm, creating a 790-800 mm usable travel window. This adjuster acts only as a travel stop for fine-tuning and does not lock or hold the load without live air pressure.
