About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-10S
The AirTAC SAIJ200X950-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 940-950 mm usable travel window, allowing you to dial back the 950 mm nominal stroke by up to 10 mm during commissioning. In the 200 mm bore class, it generates 15708 N of thrust at 0.5 MPa and reaches a maximum of 3204 kgf at 1.0 MPa.
This variant features a SUS420J2 stainless steel rod (code A) and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The G3/4 PT tapered ports manage high flow, while the 950 mm stroke requires careful external guiding to prevent excessive side-loading on the large 40 mm rod.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 940-950 mm end position on large metal forming presses to compensate for tooling wear without changing the cylinder.
Large Machine Commissioning
Adjust the rear stopper during setup to perfectly time the stroke of massive 3204 kgf actuators on automated assembly lines.
Product Size Changeover
Rapidly accommodate varying product lengths on heavy-duty conveyor systems by tweaking the 10 mm travel window during line changeovers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-10S the Right Cylinder?
Choose this 200 mm bore if you need extreme thrust (15708 N at 0.5 MPa) that smaller bores cannot provide; for example, a 160 mm bore only yields 10053 N at the same pressure. The 10 mm rear adjuster is ideal for fine-tuning the end position without adding external stops. For true load-holding without live air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster acts only as a travel stop. When replacing an ISO 15552 cylinder, match the 200 mm bore, 950 mm stroke, 10 mm adjustment, G3/4 PT ports, 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 SAIJ200AX950-10S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 950 mm nominal stroke by up to 10 mm, creating a 940-950 mm travel window. It is a stop, not a lock, so it cannot hold the load without live air.
It provides 15708 N of push force and 15080 N of pull force at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
