About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-75S
The AirTAC SAIJ200X750-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 675 to 750 mm. Delivering 15708 N of push force at 0.5 MPa, it handles heavy-duty positioning. The SUS420J2 stainless steel rod provides enhanced corrosion resistance for demanding environments.
This adjustable-stroke design allows precise end-position tuning during commissioning without external stops. It features PT tapered ports and a built-in magnet for CMSE or DMSE sensors. The rear adjuster acts purely as a travel stop and does not hold the load without continuous air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-75S Is Used
Heavy Press Tuning
Fine-tune the 675-750 mm travel window during machine setup to perfectly time heavy pressing operations without swapping cylinders.
Product Changeover
Dial back the rear stopper by up to 75 mm to accommodate varying product lengths on a high-tonnage assembly line.
Sensor Integration
Leverage the -S magnet and dual sensor grooves to mount CMSE or DMSE switches for precise end-of-stroke detection.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-75S the Right Cylinder?
Choose this 200 mm bore cylinder when an application requires substantial thrust (15708 N push at 0.5 MPa) and on-the-fly stroke trimming. If you need less force, stepping down to a 160 mm bore yields 10053 N. The 75 mm adjustment range is ideal for product changeovers, whereas a fixed SAI cylinder suits static end-stops.
For load-holding without live air, select a SAIL or BSAI cylinder instead, as this SAIJ adjuster is not a lock. Because the 750 mm stroke is long, the 40 mm rod and M36x2 thread require an external guide to prevent side-load damage. This unit is dimensionally interchangeable per ISO 15552.
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 SAIJ200AX750-75S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 75 mm, providing a usable travel window of 675 to 750 mm. It functions as a mechanical stop and does not lock the load without air pressure.
At 0.5 MPa operating pressure, it provides 15708 N of push force and 15080 N of pull force. The maximum thrust is 3204 kgf at 1.0 MPa.
