About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-75
The AirTAC SAIJ32X145-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 145 mm travel by up to 75 mm. This creates a highly flexible 70 to 145 mm usable window, perfect for dialing in exact end positions during commissioning without external stops.
This extruded aluminum profile cylinder includes sensor grooves on both sides for CMSE or DMSE switches, though this specific SKU is supplied without a magnet. The rear adjuster functions strictly as a travel stop to set the retraction endpoint and relies on the integrated air cushion for deceleration; it does not hold the load without continuous air pressure.

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 SAIJ32AX145-75 Is Used
Product Changeovers
Quickly modify the retraction endpoint across a 70 to 145 mm window to accommodate different product sizes on the same conveyor line without swapping hardware.
Commissioning Calibration
Fine-tune the final end position during machine setup to achieve exact positioning, using the rear stopper instead of adding external shims.
Variable End Stops
Set precise retract distances for testing fixtures where the required stroke length needs frequent adjustment across the 75 mm range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-75 the Right Cylinder?
The 75 mm adjustment range is ideal for product changeovers on a line where multiple end-stop distances are required from a single cylinder.
For a direct ISO 15552 replacement match, ensure you specify the 145 mm stroke, 75 mm adjuster, PT tapered port thread, and the SUS420J2 rod material. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the nominal stroke is under 300 mm, side-load stress is manageable, but external guiding is still recommended for unsupported loads. Note that for load-holding without live air, you must use a SAIL or BSAI variant.
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 SAIJ32AX145-75 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster acts as a stopper that lets you shorten the effective stroke from the nominal 145 mm down to as little as 70 mm. It sets the travel end and relies on the air cushion for deceleration, but it does not lock or hold the load without live air pressure.
