About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-50
The AirTAC SAIJ32X55-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 55 mm travel by up to 50 mm. This creates a highly versatile 5 to 55 mm usable window, perfect for dialing in exact end positions during machine commissioning without swapping hardware.
This model uses a PT G1/8 port and includes variable air cushions at both ends to manage deceleration. The rear screw acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ32AX55-50 Is Used
Machine Changeover
Quickly adapt end positions for different product sizes on a packaging line without replacing the cylinder or adding external stopper blocks.
Prototype Setup
Fine-tune the exact retraction point during initial commissioning to perfect a 5 to 55 mm pick-and-place motion.
Variable End Stops
Dial in the precise stroke limit for delicate pressing or sensing tasks where a fixed 55 mm travel might overshoot.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-50 the Right Cylinder?
Choose this 32 mm bore when your application requires precise positioning within a 5 to 55 mm travel window. The adjustable stroke is ideal for product changeovers where end-stops vary, eliminating the need to buy multiple fixed-stroke SAI cylinders.
This configuration features a PT tapered port, a SUS420J2 stainless steel rod, and no magnet. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load concerns are minimal, though external guides are still recommended for optimal cylinder longevity.
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 SAIJ32AX55-50 FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 50 mm. This means the 55 mm nominal stroke can be fine-tuned down to a 5 mm effective stroke, giving you a 5 to 55 mm usable window.
