About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-75S
The AirTAC SAIJ200X105-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This yields a highly flexible 30-105 mm usable stroke window, ideal for dialing in exact end positions during machine commissioning without swapping hardware. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, scaling up to 28274 N at 0.9 MPa.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side extruded barrel grooves. The piston rod utilizes SUS420J2 stainless steel for superior corrosion resistance, while the PT tapered port threads ensure a tight, reliable pneumatic connection at the G3/4 fittings.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-75S Is Used
Heavy Press Tuning
Fine-tune the 30-105 mm travel window during heavy press commissioning to achieve precise material deformation without adding external stops.
Product Changeover
Quickly adapt the rear stroke stop for varying product sizes on a high-force assembly line, leveraging the 75 mm adjustment range.
Dynamic End-Positioning
Set exact retraction endpoints in automated heavy machinery using the rear stopper, relying on the 3204 kgf max force for robust actuation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-75S the Right Cylinder?
Select this 200 mm bore size when your application requires extreme force, stepping up significantly from the 160 mm bore which provides 10053 N push force at 0.5 MPa. The adjustable stroke mechanism is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers, but remember the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL series.
This cylinder matches the ISO 15552 mounting interface dimensions, utilizing the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) without FB or CA brackets. Because the 105 mm nominal stroke is relatively short for this massive bore, side-load risks are minimized, though an external guide is always recommended for heavy loads. The standard speed range for this bore is 30-500 mm/s.
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 SAIJ200AX105-75S FAQ
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf of push force.
The rear adjuster screw allows you to shorten the 105 mm nominal stroke by up to 75 mm, creating a usable travel window of 30 to 105 mm. It functions as a mechanical stop to decelerate the load, not a lock, so live air is required to hold position.
