About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-50
The AirTAC SAIJ32X145-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 145 mm nominal stroke to a 95 mm minimum. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch installation.
This specific SKU is built with a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and features PT tapered port threads. The rear adjustment mechanism acts purely as a mechanical stop to set the retract end position and does not lock or hold the load without continuous air pressure. For load-holding requirements without live air, a SAIL or BSAI series cylinder would be required.

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 SAIJ32AX145-50 Is Used
Machine Changeover
Quickly adapt the end-of-stroke position from 95 to 145 mm during product size transitions without disassembling the fixture or changing the cylinder.
End-Position Tuning
Dial in the exact retract distance during commissioning using the rear stopper screw, compensating for mechanical tolerances in the assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-50 the Right Cylinder?
Choose this 32 mm bore when your application requires approximately 345 N of pull force at 0.5 MPa. If your setup demands greater thrust, stepping up to the 40 mm bore yields 528 N of pull force, while dropping down is not an option below 32 mm in this series. The 50 mm adjustment range is particularly useful for machine changeovers, allowing you to dial in the exact 95 to 145 mm travel window without physically swapping the cylinder or adding external stops.
Because the 145 mm stroke is well under the 300 mm threshold, side-load stress on the M10x1.25 rod thread is minimal, though external guides are always recommended for heavy off-axis loads. This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 standards.

- ✓ 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 SAIJ32AX145-50 FAQ
The rear adjuster screw allows you to shorten the nominal 145 mm stroke by up to 50 mm, providing a usable travel window of 95 to 145 mm. The adjuster acts as a mechanical stop and does not function as a lock, meaning the cylinder requires live air pressure to hold its position.
The maximum thrust is 82 kgf at 1.0 MPa.
