About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-30
The AirTAC SAIJ32X65-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 35 to 65 mm. Delivering 402 N of push force at 0.5 MPa, it integrates a 12 mm piston rod with an M10x1.25 thread. The barrel is extruded aluminum with sensor grooves on both sides for flexible mounting.
This configuration uses a SUS304 stainless steel rod for superior corrosion resistance and PT tapered port threads. The external rear stopper allows fine end-position tuning at commissioning without swapping the cylinder or adding external stops. The adjuster acts solely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-30 Is Used
Variable End-Stop Tuning
Dial in the exact retraction point between 35 and 65 mm during machine commissioning without machining new hard stops.
Product Changeover
Quickly adjust the cylinder's effective stroke on the line when switching between product sizes that require different travel distances.
Position Calibration
Fine-tune the end-of-stroke position to calibrate sensor triggers and mechanical interfaces during initial equipment setup.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-30 the Right Cylinder?
Choose this 32 mm bore model when an application requires precise variable end-stops within a 35-65 mm window, delivering 402 N of push force at 0.5 MPa. If your setup needs more thrust, stepping up to the 40 mm bore yields 628 N. The rear adjuster allows rapid product changeover without external stops, but note that the SAIJ does not hold position without live air; for load-holding, consider the SAIL or BSAI series.
This model is dimensionally interchangeable per ISO 15552. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is under 300 mm, side-load concerns are minimal, but long unsupported strokes still need an external guide. Sensors are not included as no magnet is specified.
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 SAIJ32BX65-30 FAQ
It features a rear adjusting screw that shortens the effective stroke by up to 30 mm. This creates a usable travel window of 35 to 65 mm, allowing you to fine-tune the end position without changing the cylinder.
At 0.5 MPa, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. It can reach a maximum push force of 724 N at 0.9 MPa.
