About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-100S
The AirTAC SAIJ200X280-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 280 mm travel by up to 100 mm. This yields a usable 180-280 mm end-position window, enabling precise fine-tuning at commissioning or during product changeovers without swapping out the unit. As the largest standard bore, it delivers immense thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. Fluid supply is routed through PT G3/4 tapered ports, and the extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster acts solely as a mechanical stop to set the travel end; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-100S Is Used
Heavy Press Tuning
Fine-tune the 180-280 mm travel window during setup to apply precise pressing force on large assemblies without adding external mechanical stops.
Product Size Changeover
Quickly adjust the rear stopper to accommodate varying package dimensions on a high-throughput line, shifting the end-position seamlessly.
Heavy-Duty Positioning
Leverage the 15708 N push force to move substantial pallets or molds, dialing in the exact retraction point during initial machine commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX280-100S the Right Cylinder?
Selecting this 200 mm bore is appropriate when your application requires extreme force, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. Conversely, if 15708 N is excessive, a smaller bore saves space and air consumption. Choose this adjustable-stroke configuration over a fixed-stroke SAI when you need variable end-stops to accommodate multiple product sizes on a single line. For load-holding without continuous air pressure, note that the rear adjuster here is not a lock; you would need to specify an SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
When matching an ISO 15552 replacement, ensure you specify the 200 mm bore, 280 mm stroke, 100 mm adjustment range, PT G3/4 port thread, and the -S magnet option. Because the stroke is 280 mm, the 40 mm rod diameter and M36x2 thread provide rigidity, but long unsupported travel still necessitates an external guide to prevent side-loading damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ200AX280-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 280 mm by up to 100 mm, providing a usable travel window of 180-280 mm. The adjuster acts as a mechanical stop to set the end position and is not a lock, meaning it cannot hold the load without live air pressure.
