About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-75
The AirTAC SAIJ32X80-75 is a double-acting 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 flexible 5-80 mm usable travel window for precise end-position tuning. Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, it suits light-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. It features PT tapered port threads (G1/8) and adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-75 Is Used
Variable End-Stop Tuning
Dial in the exact clamping distance on short-stroke assembly fixtures, adjusting the travel window anywhere from 5 to 80 mm during commissioning.
Product Changeover Setup
Quickly reposition the retract end-stop on packaging lines when switching between different product sizes without changing the cylinder hardware.
Light-Duty Positioning
Handle delicate component placement tasks requiring up to 402 N of push force, utilizing the SUS420J2 stainless steel rod for environmental resilience.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-75 the Right Cylinder?
Choose this 32 mm bore when you need standard 0.5 MPa thrust (402 N push) but require significant on-the-fly stroke variability without swapping cylinders. If your application demands less adjustability, a fixed-stroke SAI cylinder or a smaller SAIJ40X80-10 (628 N push) might suffice. The rear adjuster acts solely as a travel stop; it does not hold the load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 80 mm nominal stroke, 75 mm adjustment range, PT G1/8 ports, and your required mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the 80 mm stroke is short, side-loading risks are minimal, but always ensure the piston rod is properly aligned to prevent premature seal wear.
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 SAIJ32AX80-75 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke from 80 mm down to as little as 5 mm. This provides a 5-80 mm adjustable travel window for fine-tuning at commissioning without external stops.
At a 0.5 MPa operating pressure, the SAIJ32X80-75 provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at its maximum 0.9 MPa pressure.
