About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-10S
The AirTAC SAIJ200X400-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 400 mm travel back by up to 10 mm. This yields a precise 390-400 mm usable end-position window, allowing you to fine-tune machine stops at commissioning without adding external physical stops or swapping the cylinder. Delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa, it is built for heavy-duty positioning.
This variant includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and ships with a piston magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the rear adjuster functions strictly as a travel stop to set deceleration endpoints, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-10S Is Used
Heavy Press Tonnage
Provides up to 318 kgf at 1.0 MPa for heavy stamping and pressing operations requiring precise 390-400 mm end-stop tuning.
Product Changeover Stops
Dial in the 10 mm rear adjustment during line changeovers to accommodate varying product lengths without replacing the actuator.
Large Assembly Jigs
Handles heavy structural components with a 40 mm SUS420J2 stainless steel rod, offering superior corrosion resistance for industrial jigs.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-10S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum thrust in the standard SAIJ range, as stepping down to a 160 mm bore reduces your 0.5 MPa push force to 10053 N. The 10 mm rear adjustment window is ideal for product changeovers where exact end-position tuning is critical. Because the stroke is 400 mm, the 40 mm diameter rod provides robust support, but an external guide is recommended to prevent side-load binding over long unsupported travels.
For drop-in ISO 15552 replacements, match the 200 mm bore, 400 mm stroke, 10 mm adjustment, PT tapered ports, and -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If the machine must hold the load statically without live air pressure, use an SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on this adjuster.

- ✓ 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 SAIJ200AX400-10S FAQ
At a 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 delivers a peak push force of 318 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 400 mm stroke by up to 10 mm, creating a 390-400 mm usable travel window. It sets the end position and deceleration point but does not lock the load without live air pressure.
