About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-50S
The AirTAC SAIJ100X75-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits on-the-fly end-position tuning.
This specific SKU includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a -S magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates dual sensor grooves, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1 and TCM2 options.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX75-50S Is Used
Variable End-Stop Forming
Dial in the exact 25 to 75mm travel window during machine setup to accommodate different material thicknesses without changing cylinders.
Product Changeover Diverter
Quickly reposition the retract stop on a packaging line to handle varying package lengths, using the rear screw for immediate fine-tuning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-50S the Right Cylinder?
The 50mm adjustment range is ideal for product changeovers where the end-stop varies, eliminating the need to swap a fixed-stroke SAI cylinder during setup.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series. To match this ISO 15552 cylinder, specify a 100mm bore, 75mm stroke, 50mm adjustment, PT ports, SUS420J2 rod, and a -S magnet.
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 SAIJ100AX75-50S FAQ
At 0.9MPa, the push force reaches 7068N.
The rear adjuster screw lets you shorten the 75mm nominal stroke by up to 50mm, creating a usable travel window of 25 to 75mm. This stopper decelerates the end of travel but does not lock the load without continuous air pressure.
