About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-50
The AirTAC SAIJ32X65-50 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This adjustability allows you to dial in the exact end position at commissioning without adding external stops.
This configuration features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. It uses a PT tapered port thread, operates at speeds of 30-800mm/s, and includes variable air cushions at both ends. Note that the rear adjuster acts only as a travel stop and does not hold the load without live 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 SAIJ32AX65-50 Is Used
Machine Changeovers
Dial in the 15-65mm retraction point during product size changes without physically swapping the cylinder or adding external mechanical stops.
Prototype Positioning
Ideal for prototype tooling where the exact end-of-stroke position is unknown, allowing 50mm of rear adjustment to find the optimal travel distance.
Actuator Setup
Fine-tune the retracted position of small pneumatic actuators during initial machine commissioning to prevent mechanical interference.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-50 the Right Cylinder?
If your setup demands less force, stepping down is not an option in this size range, but stepping up to a 40mm bore yields 628N. The 50mm adjustment range is exceptionally wide for a 65mm stroke, making it perfect for prototyping or product changeovers where the exact retraction point varies. For load-holding without live air, consider the SAIL or BSAI series instead of relying on this stopper.
To replace an ISO 15552 cylinder, match the 32mm bore, 65mm stroke, PT port thread, and your desired mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because this specific unit lacks the -S magnet option, it cannot host CMSE or DMSE sensors.

- ✓ 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 SAIJ32AX65-50 FAQ
At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 50mm. This creates a usable travel window of 15mm to 65mm, depending on how far the adjuster is screwed in. It functions as a stop, not a lock, and requires live air to hold position.
