About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-75
The AirTAC SAIJ100X75-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 75mm stroke that can be dialed back by up to 75mm, creating a 0-75mm usable travel window for exact end-position tuning during commissioning.
This adjustable design eliminates the need to swap cylinders or add external stops when finalizing machine setup. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this specific configuration omits the internal magnet. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ100BX75-75 Is Used
Press Stroke Calibration
Dial in the exact 0-75mm travel window during press assembly to accommodate varying material thicknesses without changing the cylinder.
Machine Changeover
Quickly adjust the retract end-stop on packaging lines when switching between different product sizes, minimizing downtime.
End-Position Trimming
Fine-tune the final resting position of clamps and stops during machine commissioning using the rear adjustment screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-75 the Right Cylinder?
The 25mm rod and M20x1.5 thread offer high rigidity, but because the 75mm stroke is relatively short, side-load risks are minimal compared to longer travels.
The rear adjuster acts strictly as a mechanical stop to fine-tune the retract position and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. To match this ISO 15552 interchangeable cylinder, specify the 100mm bore, 75mm stroke, 75mm adjustment, PT G1/2 ports, and the appropriate mounting accessory.
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 SAIJ100BX75-75 FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 801 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 75mm down to 0mm. It sets the retract end position but does not lock the load without live air pressure.
