About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-40
The AirTAC SAIJ200X290-40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708N of thrust at 0.5 MPa. Its extruded aluminum barrel design integrates an external rear stroke adjuster, allowing you to fine-tune the effective travel within a 250-290 mm window. This eliminates the need to physically swap cylinders during product changeovers or commissioning tweaks.
Equipped with a SUS420J2 stainless steel rod (material code A), this 200mm bore unit handles demanding environments while resisting corrosion. The rod end features an M36x2 thread, and pneumatic connections use PT tapered G3/4 ports. Because the rear adjuster functions strictly as a travel stop rather than a locking mechanism, it decelerates the load at the end of stroke but will not hold the cylinder stationary without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-40 Is Used
Heavy Press Tuning
Dial in the exact 250-290mm travel end-stop during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Assembly Line Changeover
Quickly adjust the rear stopper by up to 40mm to handle different product sizes on an assembly line, minimizing machine downtime between runs.
Industrial Forming
Leverage the 15708N push force at 0.5 MPa for robust forming operations, using the rear screw to fine-tune the retraction end position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-40 the Right Cylinder?
Selecting this 200mm bore model is appropriate when your process requires extreme push force, such as 15708N at 0.5 MPa or up to 3204 kgf at 1.0 MPa. If your application needs less force, stepping down to a 160mm bore provides 10053N at 0.5 MPa, which might better suit medium-heavy machinery. The 40mm adjustment range on this 290mm stroke is ideal for dialing in precise end positions on the fly without machining external stopper blocks.
When replacing an ISO 15552 cylinder, match the 200mm bore, 290mm nominal stroke, 40mm adjustment, PT G3/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Since the total stroke is 290mm, an external guide is recommended to prevent excessive side-loading on the M36x2 rod. For applications requiring true load-holding without continuous air supply, consider the AirTAC SAIL or BSAI series instead of relying on this stopper.
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 SAIJ200AX290-40 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear external screw acts as a mechanical stop, allowing you to shorten the usable stroke from 290mm down to 250mm. This adjuster only sets the travel end position and does not lock or hold the load without continuous air pressure.
