About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-30S
The AirTAC SAIJ100X375-30-S is a double-acting ISO 15552 profile cylinder featuring a SUS420J2 stainless steel rod and an integrated rear adjuster. It provides a 345-375mm usable travel window by trimming up to 30mm off the 375mm nominal stroke, allowing precise end-position tuning at commissioning without swapping the barrel or adding external stops.
This extruded aluminum profile cylinder uses PT tapered G1/2 ports and variable air cushions at both ends to manage deceleration. The rear stopper sets the retract travel end but does not hold the load without live air pressure; for pilot-operated load holding, consider SAIL or BSAI variants. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX375-30S Is Used
Variable End Stops
Dial in the 345-375mm travel window during machine setup to accommodate varying product lengths without changing cylinders.
Product Changeover
Quickly adjust the rear stopper on the line when switching product sizes, using the 30mm trim range to fine-tune the retract position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-30S the Right Cylinder?
The adjustable stroke is ideal for fine-tuning machine setup, whereas a fixed SAI cylinder is preferred if the exact travel never changes.
Because the 375mm stroke is relatively long, the 25mm rod diameter should carry side loads carefully; long unsupported strokes still need an external guide to prevent premature wear. For ISO 15552 replacement matching, specify bore 100, stroke 375, 30mm adjustment, PT port thread, the required mounting, and the -S magnet. The SAIJ mounting set omits FB, CA, CB, and CR brackets.
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 SAIJ100AX375-30S FAQ
At 0.7MPa the push force increases to 5497N.
The rear adjuster acts as a stopper that lets you trim the effective travel back by up to 30mm from the 375mm nominal stroke, creating a 345-375mm usable window. It is a travel stop, not a lock, and does not hold the load without live air.
