About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-75
The AirTAC SAIJ100X200-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 200 mm stroke that can be dialed back by up to 75 mm, yielding a precise 125-200 mm usable travel window for highly flexible end-position tuning.
This variant uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to set the retract end position; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 125-200 mm window during commissioning without swapping out the physical cylinder.
Product-Size Changeover
Quickly adapt automated machinery to different product lengths by adjusting the rear stopper screw on the fly, minimizing downtime.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-75 the Right Cylinder?
Choose this 100 mm bore when an application requires substantial thrust—such as 5497 N at 0.7 MPa—combined with a highly variable stroke length. If your force needs are lower, stepping down to an 80 mm bore provides 3518 N at 0.7 MPa, whereas a 125 mm bore offers 8590 N. The 75 mm adjustment range is ideal for machine setups requiring frequent product-size changeovers, eliminating the need to physically swap cylinders or bolt on external stops.
When ordering, specify the 100 mm bore, 200 mm stroke, 75 mm adjustment, PT port thread, and SUS420J2 rod material. Note that SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Although the 25 mm rod diameter handles side loads well, any stroke of 300 mm or more on this frame requires an external guide to prevent rod binding.
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 SAIJ100 Adjustable Cylinder SAIJ100AX200-75 FAQ
The maximum force at 1.0 MPa is 801 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 200 mm down to as little as 125 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
