About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX45-30
The AirTAC SAIJ100X45-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 15 to 45 mm. The piston rod utilizes SUS420J2 stainless steel (code A), providing enhanced corrosion resistance for demanding environments.
This model uses PT tapered port threads and includes variable air cushions at both ends to manage impact deceleration. The extruded aluminum barrel integrates dual-side sensor grooves, allowing direct mounting of position switches. Because no magnet is specified, electronic DMSE or reed CMSE sensors would require an -S variant to function.

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 SAIJ100AX45-30 Is Used
Press Fit Tuning
Dial in the exact 15-45 mm travel during press fits to accommodate varying material thicknesses without swapping cylinders.
Machine Changeover
Quickly adjust the end-stop position on packaging lines when switching to a new product size, minimizing downtime.
Assembly Station Setup
Fine-tune the clamping reach at commissioning to ensure precise alignment and prevent over-travel on heavy assemblies.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX45-30 the Right Cylinder?
The adjustable stroke is selected over a fixed SAI when a process requires exact end-position tuning during commissioning without adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
With a 45 mm stroke, side-load concerns are minimal, but the 25 mm rod and M20x1.5 thread offer high rigidity. This SAIJ model supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 standards.
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 SAIJ100AX45-30 FAQ
The operational speed range is 30-800 mm/s.
The rear adjuster screw lets you trim the 45 mm nominal stroke back by up to 30 mm, yielding a usable travel window of 15 to 45 mm for precise end-position tuning.
