About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-20S
The AirTAC SAIJ200X230-20-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, making it suited for heavy-duty operations. The integrated -20 mm adjustment screw allows you to trim the effective travel back, creating a precise 210-230 mm usable window for fine-tuning end positions during commissioning.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads match the G3/4 air supply required for this 200 mm bore size.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-20S Is Used
Heavy Press Tuning
Dial in the exact 210-230 mm end position during heavy press commissioning without changing the cylinder or adding external stops.
Product Size Changeover
Adapt automated lines quickly when product dimensions shift slightly, using the rear screw to trim the stroke by up to 20 mm.
Large Assembly Positioning
Move massive components into place with 15708N of push force, relying on the fine adjustment to perfect the resting spot.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-20S the Right Cylinder?
Selecting this 200 mm bore cylinder provides a maximum thrust of 3204 kgf at 1.0 MPa, stepping up significantly from a 160 mm bore that yields 10053N at 0.5 MPa. The adjustable stroke is ideal for heavy product changeovers where the exact end-stop varies by 20 mm, eliminating the need to physically swap cylinders or bolt on external stopper blocks. For applications requiring the load to be held without live air pressure, note that this rear adjuster acts only as a travel stop and not a lock; an external rod lock or a related SAIL pneumatic lock cylinder is required.
Because the 230 mm stroke exceeds the 300 mm side-load caution threshold, an external guide should support the rod to prevent excessive wear. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. It operates at speeds of 30-500 mm/s and features variable air cushions at both ends to decelerate the heavy load.

- ✓ 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 SAIJ200AX230-20S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa operating pressure, it delivers a peak thrust of 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 230 mm stroke by up to 20 mm. This creates a 210-230 mm usable travel window for fine-tuning the end position at commissioning without swapping the cylinder.
