About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-100S
The AirTAC SAIJ200X290-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it suited for heavy-duty positioning. The integrated -100 adjustment code provides a generous 190-290mm usable travel window, allowing you to dial back the nominal 290mm stroke by up to 100mm during commissioning.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. Fluid is filtered air, operating pressure ranges from 0.15 to 1.0 MPa, and the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-100S Is Used
Heavy Stamping Positioning
Dial in the exact 190-290mm end-stop for large metal stamping or forming presses, accommodating different die heights without external stopper blocks.
Automated Line Changeover
Quickly adjust the stroke window during product size transitions on a high-force assembly line, reducing machine setup time via the rear screw.
Large Material Handling
Move heavy payloads or pallets with up to 15708N of push force, using the adjustable travel to fine-tune deceleration and final resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-100S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application requires extreme force, stepping up significantly from a 160mm bore that provides 10053N push force at 0.5 MPa. The adjustable stroke is chosen over a fixed SAI model when you need variable end-stops for product changeovers without physically swapping the cylinder or adding external stops. Because the nominal stroke is 290mm, an external guide is recommended to manage side-load, as even the robust 40mm rod and M36x2 thread cannot fully support long unsupported loads.
When matching an ISO 15552 replacement, verify the 200mm bore, 290mm nominal stroke, -100 adjustment, PT tapered ports, and the -S magnet. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for positive load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR.
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 SAIJ200AX290-100S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw allows you to shorten the effective travel by up to 100mm. This creates a usable stroke window of 190-290mm from the nominal 290mm stroke, enabling fine-tuning of the end position without replacing the cylinder.
