About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-30S
The AirTAC SAIJ32X65-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force and 345N of pull force at 0.5 MPa. The built-in rear stopper allows you to trim the effective travel, providing a usable stroke window of 35 to 65 mm for precise end-position tuning during machine commissioning.
This specific configuration features a SUS304 stainless steel rod for enhanced corrosion resistance and includes a piston magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. It uses a PT tapered port thread and relies on variable air cushions at both ends to decelerate the load. Remember that the rear adjuster acts only as a travel stop, not a lock, so it will not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-30S Is Used
Machine Changeover
Dial in the exact 35 to 65 mm retract position during product size changes without swapping the cylinder or bolting on external stops.
End-Stop Calibration
Fine-tune the final end-position at commissioning using the rear adjusting screw, ensuring precise placement of small parts.
Sensor Trigger Setup
Leverage the -S magnet and dual sensor grooves to mount CMSE or DMSE switches exactly where needed along the adjusted travel path.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-30S the Right Cylinder?
Select this 32mm bore model when your application requires fine-tuning of the retract position within a 35 to 65 mm travel window without adding external stops. If your setup needs higher force, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. Conversely, if you require a fixed standard stroke without the adjustment mechanism, the standard SAI series is the appropriate choice.
For a drop-in ISO 15552 replacement, match the 32mm bore, 65mm stroke, 30mm adjustment range, PT port, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 12mm rod and M10x1.25 thread carry moderate side loads, always use an external guide for lateral forces. For load-holding without live pressure, consider the SAIL or BSAI series instead.
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 SAIJ32BX65-30S FAQ
The rear adjusting screw acts as a mechanical stopper that shortens the effective stroke. For this 65mm nominal stroke model, the -30 code means you can trim the travel back by up to 30mm, giving a usable window of 35 to 65mm.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 801N.
