About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-30S
The AirTAC SAIJ200X190-30-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. By turning the rear stopper, you can trim the effective travel, creating a precise 160-190mm usable window for your exact positioning needs.
This unit includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and a PT tapered port thread. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side barrel grooves. The rear adjuster acts purely as a mechanical stop to set deceleration endpoints; it is not a lock and cannot hold the load without live air.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-30S Is Used
Heavy Press Tuning
Dial in the exact 160-190mm end position during heavy press commissioning to accommodate varying material thicknesses without adding external stops.
Product Size Changeover
Quickly adjust the cylinder's travel limit on packaging lines when switching to a new product size, saving hours of mechanical retooling.
Automated Assembly Stops
Set precise mechanical deceleration endpoints for heavy-duty automated assembly robots, ensuring repeatable end-of-stroke positioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-30S the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme force—up to 15708N at just 0.5 MPa—and requires fine end-position tuning at commissioning. If your setup needs less force, stepping down to a 160mm bore yields 10053N, whereas moving up to this 200mm bore provides a maximum thrust of 15708N at standard operating pressure. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers without swapping the entire cylinder.
For ISO 15552 interchangeability, match the 200x190mm dimensions, the 30mm adjustment range, PT G3/4 port, and the -S magnet. Since the stroke is 190mm, side-load risks are moderate, but for any stroke of 300mm or more, an external guide is mandatory to protect the rod from bending. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For true load-holding without live air pressure, select the SAIL or BSAI series instead.

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 SAIJ200AX190-30S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 190mm nominal stroke by up to 30mm, providing a usable travel window of 160-190mm. This allows fine-tuning of the end position without replacing the cylinder, though it does not lock or hold the load without continuous air pressure.
