About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-30S
The AirTAC SAIJ32X55-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 25 to 55 mm, letting you dial in the exact retract position without adding external stops. It delivers 402 N of push force at 0.5 MPa and uses a PT tapered port.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, and it features an SUS420J2 stainless steel rod (option A) for improved corrosion resistance. The extruded aluminum barrel keeps the footprint dimensionally interchangeable with ISO 15552 cylinders, and the adjustable stopper acts purely as a travel end, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-30S Is Used
Machine Setup Changeover
Dial in the exact 25 to 55 mm retract position during product changeover without swapping the cylinder or bolting on external stops.
Variable End Stops
Fine-tune the retract end position on packaging or assembly machines to accommodate minor variations in component sizing.
Sensor-Ready Positioning
Leverage the integrated magnet with DMSE electronic sensors to confirm the adjusted end position in automated control systems.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-30S the Right Cylinder?
Choose this 32 mm bore if your application requires 402 N push force at 0.5 MPa and precise end-position tuning. If you need less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. Select this adjustable-stroke model over a fixed SAI when you need frequent product changeover or commissioning fine-tune capabilities. The rear screw sets the travel end but does not hold the load without live air; for true load holding, consider SAIL or BSAI. Configuration: 32 mm bore, 55 mm stroke, 30 mm adjustment, PT port, SUS420J2 rod, magnet included.
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 SAIJ32AX55-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you trim the 55 mm nominal stroke back by up to 30 mm, creating a usable travel window of 25 to 55 mm. The adjuster acts as a travel stop and does not lock the load without live air pressure.
