About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-20
The AirTAC SAIJ100X135-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the effective travel into a precise 115-135 mm window. The piston rod utilizes SUS420J2 stainless steel (code A), offering enhanced corrosion resistance compared to standard carbon steel.
This model features PT tapered port threads and a G1/2 fluid connection. Instead of relying on external stops, the integrated rear screw mechanism allows you to fine-tune the retract end-position directly during commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic solid-state switches if position feedback is later required.

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 SAIJ100AX135-20 Is Used
Product Changeover
Quickly dial in the 115-135 mm travel window during line changeovers to accommodate different package sizes without swapping the cylinder.
End-Position Tuning
Fine-tune the retract stroke at machine commissioning to perfect the seating force against a workpiece, avoiding the need for external stopper blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-20 the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI cylinder when you need a variable end-stop to accommodate multiple product sizes on the same line.
For any stroke length of 135 mm, side-load is generally manageable, but for longer unsupported travels of 300 mm or more, an external guide is recommended to prevent rod binding. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; if mechanical locking is required, consider the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting 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 SAIJ100AX135-20 FAQ
It features a rear adjusting screw that lets you shorten the nominal 135 mm stroke by up to 20 mm. This creates a usable travel window of 115-135 mm, allowing you to set the exact retract end-position during commissioning without adding external stops.
The maximum operating pressure is 1.0 MPa.
