About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-75S
The AirTAC SAIJ100X200-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches.
This model is built with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads (G1/2). The rear adjuster acts purely as a mechanical stop to fine-tune the retract position during commissioning or product changeovers, meaning you never have to swap the cylinder or bolt on external stops. Note that this adjuster is not a locking device; it cannot hold a load without live air pressure.

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 SAIJ100AX200-75S Is Used
Variable Product Changeover
Quickly reconfigure the 125-200mm travel window for different packaging formats without replacing the cylinder or adding external mechanical stops.
Precision End-Stop Tuning
Dial in the exact retract position during machine commissioning using the rear screw, perfect for aligning heavy 3927N clamping forces precisely.
Multi-Format Assembly Lines
Adapt automated assembly stations to multiple part lengths on the fly, relying on the robust 25mm rod to handle heavy tooling weights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX200-75S the Right Cylinder?
The 75mm adjustment window is ideal for machinery that frequently handles varying product sizes, allowing operators to dial in the exact 125-200mm stroke on the fly instead of ordering custom fixed-length SAI cylinders. For load-holding without continuous air pressure, this cylinder will not suffice—you must integrate an external pilot-operated check valve or select a SAIL (air-released lock) or BSAI (clamp-lock) variant.
When replacing an ISO 15552 cylinder, match the 100mm bore, 200mm nominal stroke, 75mm adjustment, PT G1/2 port, and the -S magnet requirement. Mounting options for this adjustable series are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 200mm stroke is relatively short for this bore, side-load stress is minimal, though the robust 25mm rod and M20x1.5 rod thread naturally handle high off-center loads if your application demands it.
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 SAIJ100AX200-75S FAQ
At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 75mm. This creates a usable travel window of 125-200mm, enabling fine-tuning without swapping the cylinder.
