About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-30
The AirTAC SAIJ32X80-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 50-80 mm usable travel window, letting you dial back the 80 mm nominal stroke by up to 30 mm during machine commissioning. In the 32 mm bore class, it yields 402 N of push force at 0.5 MPa and 563 N at 0.7 MPa.
This SKU features a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes PT tapered G1/8 air ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear stopper mechanism fine-tunes the end position without requiring external stops, though it functions only as a travel limiter and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-30 Is Used
Product Changeovers
Dial in the 50-80 mm travel window during packaging format changes to accommodate varying product lengths without replacing the cylinder.
Commissioning Calibration
Fine-tune the exact retract end-position during initial machine setup, preventing the need to bolt on external mechanical stops.
Light Assembly Clamping
Provides repeatable clamping using 402 N of push force at 0.5 MPa, with the rear screw allowing precise depth control for delicate components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 563 N push force at 0.7 MPa; stepping up to a 40 mm bore increases that output to 879 N. The adjustable stroke is ideal for product changeovers where exact end-of-trim positioning varies, saving the time of physically swapping a fixed-stroke SAI cylinder. For a dimensionally interchangeable ISO 15552 replacement, match the 32 mm bore, 80 mm stroke, 30 mm adjustment, PT G1/8 port, and standard mounting interface. Since this model lacks the -S magnet suffix, it cannot host AirTAC CMSE or DMSE sensors without a configuration update. If your setup requires load holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the rear stopper.
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 SAIJ32AX80-30 FAQ
The 32 mm bore generates 402 N of push force and 345 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop that shortens the 80 mm nominal stroke by up to 30 mm, providing a usable travel window of 50-80 mm. It only sets the end position and does not lock or hold the load without live air pressure.
