About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-75S
The AirTAC SAIJ32X80-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 80 mm stroke that can be dialed back by up to 75 mm, yielding a highly versatile 5 to 80 mm usable travel window for precise commissioning. Delivering 402 N of push force at 0.5 MPa, this compact 32 mm bore unit is designed for demanding changeovers.
This variant includes a magnet for position sensing with CMSE reed or DMSE electronic switches. It features a SUS420J2 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-75S Is Used
Variable End-Stop Tuning
Dial in the exact end position from 5 to 80 mm during machine commissioning to accommodate varying material thicknesses without external stopper hardware.
Product Size Changeover
Quickly adjust the retract stroke on packaging lines when switching between different package dimensions, saving downtime on the production floor.
Precision Assembly Pressing
Leverage the 402 N push force and fine stroke adjustment to press delicate components to a precise, repeatable depth without bottoming out.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-75S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires 402 N of push force at 0.5 MPa. If your process demands less force, stepping down is not an option in this size range, but stepping up to a 40 mm bore yields 628 N. The 75 mm adjustment range is ideal for machines processing variable product sizes, allowing operators to fine-tune the end position without swapping cylinders or adding external stops. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding without pressure, consider an SAIL or BSAI cylinder.
To replace an ISO 15552 cylinder, match the 32 mm bore, 80 mm stroke, 75 mm adjustment, PT port, and the -S magnet requirement. Because the stroke is under 300 mm, side-load stress is minimal, though the 12 mm rod and M10x1.25 thread still require standard alignment practices.
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 SAIJ32AX80-75S FAQ
It features a rear adjusting screw that acts as a physical stop, allowing you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 5 to 80 mm. The adjuster only sets the travel end; it does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ32X80-75-S provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
