About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-20
The AirTAC SAIJ32X135-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 115 to 135 mm without swapping out the unit. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This SKU is configured with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The rear adjustment screw acts purely as a mechanical stop to set the retract end position during commissioning, and it does not hold the load dynamically without live air pressure. Pneumatic flow is controlled via a PT tapered G1/8 port, and the unit reaches speeds up to 800 mm/s.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32AX135-20 Is Used
Machine Commissioning
Dial in the exact retract position within the 115-135 mm window during initial setup to align tooling without machining custom spacers.
Product Changeover
Quickly adapt the end-stop for varying part sizes on a packaging line, using the rear screw rather than swapping the entire cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-20 the Right Cylinder?
Choose this 32 mm bore when your application requires precise positioning of lighter loads up to roughly 82 kgf at 1.0 MPa. The 20 mm rear adjuster on this specific model is ideal for product changeovers where the exact end-of-stroke varies slightly, eliminating the need to machine external stops or replace a fixed-stroke SAI cylinder.
Because the 135 mm stroke is under the 300 mm threshold, side-load stress on the 12 mm rod is minimal, though an external guide is still recommended for heavy lateral loads. This cylinder is dimensionally interchangeable per ISO 15552, utilizing a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your process requires true load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a locking mechanism.
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 Adjustable Cylinder SAIJ32 SAIJ32AX135-20 FAQ
The rear adjuster screw lets you mechanically shorten the nominal 135 mm stroke by up to 20 mm, providing an effective travel window of 115 to 135 mm. It acts as a physical stop to fine-tune the end position and is not a lock, meaning the cylinder still requires live air to hold its load.
If you increase the operating pressure to 0.9 MPa, the push force rises to 724 N.
