About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-75
The AirTAC SAIJ32X125-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the nominal 125 mm travel back by up to 75 mm, creating a highly flexible 50-125 mm usable positioning window. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic switches if position feedback is later required.
Because the rear screw acts purely as a mechanical stop to set the end-of-travel position, it does not lock the load or hold position without continuous live air pressure. This model uses the standard SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, intentionally omitting the FB, CA, CB, and CR styles found on some other ISO variants.

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 SAIJ32AX125-75 Is Used
Machine Changeover
Dial in the 50-125 mm stroke window during product size transitions to set new end-stops without replacing hardware.
Assembly Positioning
Fine-tune the exact extend position of a tooling head at commissioning to achieve precise part placement.
Variable End Stops
Adjust the rear mechanical stop on the fly to accommodate varying material lengths fed into a workstation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-75 the Right Cylinder?
Selecting this 32 mm bore cylinder makes sense when your application requires on-the-fly end-position tuning during commissioning or frequent product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. If your setup demands greater clamping power, stepping up to the 40 mm bore increases thrust to 628 N at 0.5 MPa; conversely, dropping to a smaller bore would sacrifice too much force for most standard industrial tasks. When matching ISO 15552 replacements, verify the 125 mm stroke, 75 mm adjustment range, PT port thread, and your required mounting bracket.
Since the 125 mm stroke is relatively short, side-loading on the 12 mm rod is minimal, though external guiding remains a best practice for heavy lateral loads. Remember that the air cushion and rear stopper only decelerate the piston—they do not function as a brake. For true load-holding without pneumatic pressure, consider an external rod lock or pilot-operated check valve.
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 SAIJ32AX125-75 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf of push force.
The rear adjuster screw lets you shorten the 125 mm nominal stroke by up to 75 mm, yielding a usable travel window of 50 to 125 mm. This stopper sets the end position but does not lock the load without live air pressure.
