About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-30
The AirTAC SAIJ32X55-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 25 to 55 mm. The extruded aluminum barrel features sensor grooves on both sides, ensuring easy installation of CMSE or DMSE switches if position sensing is added later.
This model utilizes PT tapered port threads (G1/8) and achieves speeds of 30-800 mm/s. The rear mechanical stopper allows you to dial in the exact end position during commissioning without adding external stops. Remember that this adjuster acts solely 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 SAIJ32AX55-30 Is Used
End-Position Tuning
Dial in the exact retract distance between 25 and 55 mm during machine commissioning to perfect part seating without swapping cylinders.
Product Changeovers
Quickly adjust the stroke stop on the fly when running a new batch of varying-sized components on the same assembly line.
Light-Duty Clamping
Apply 402 N of clamping force at 0.5 MPa while fine-tuning the approach distance to avoid crushing delicate workpieces.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-30 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning within a 25-55 mm window. The adjustable stroke is ideal for product changeovers on a line, whereas a fixed SAI cylinder is better for static, unchanging endpoints. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 55 mm nominal stroke, 30 mm adjustment range, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). The 12 mm rod and M10x1.25 thread handle moderate side loads well, though any stroke over 300 mm requires an external guide.
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 SAIJ32AX55-30 FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 55 mm nominal stroke by up to 30 mm. This creates a usable travel window of 25 to 55 mm. It only sets the travel end and does not lock the load without live air.
