About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-75S
The AirTAC SAIJ200X900-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the effective travel down to a usable 825-900 mm window. Delivering a robust 15708 N push force at 0.5 MPa, this 200 mm bore actuator handles heavy-duty positioning with ease. The integrated -S magnet supports CMSE reed and DMSE solid-state sensors for precise end-of-travel detection.
This unit features a SUS420J2 stainless steel rod (code A) and PT tapered port threads for a reliable, high-integrity pneumatic connection. Because it is a profile cylinder with an extruded aluminum barrel, it provides dual sensor grooves while maintaining a dimensionally interchangeable ISO 15552 mounting interface. The rear adjuster acts purely as a travel stop for product changeovers, meaning it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-75S Is Used
Heavy Press Positioning
Dial in the exact 825-900 mm end-stop for large stamping or pressing operations without swapping actuators during format changes.
Pallet Diverter Setup
Adjust the retract stopper on the fly to accommodate different pallet lengths on a heavy-duty transfer line.
Automated Assembly Tuning
Fine-tune the stroke end-position during machine commissioning to guarantee perfectly seated heavy components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-75S the Right Cylinder?
Selecting this 200 mm bore model provides a maximum push force of 15708 N at 0.5 MPa, stepping up significantly from the 100 mm bore variant which offers 3927 N. The 75 mm adjustment range is ideal for machinery requiring variable end-stops during commissioning or product-size changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. When migrating to this ISO 15552 actuator, match your exact 900 mm stroke, 75 mm adjustment, PT port threads, and the -S magnet requirement. For any stroke of 900 mm, you must use an external guide to prevent excessive side-loading on the 40 mm rod. Note that the rear adjuster and air cushions only decelerate the load; for true load-holding without live air, specify a SAIL or BSAI cylinder.
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 SAIJ200AX900-75S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can deliver up to 21991 N push force at 0.7 MPa.
The rear adjuster screw allows you to shorten the 900 mm nominal stroke by up to 75 mm, creating a usable 825-900 mm travel window. This stopper sets the end position but does not lock the load without continuous air pressure.
