About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-20
The AirTAC SAIJ32X75-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel. With a 75 mm nominal stroke and a 20 mm adjustment screw, you get a usable 55-75 mm travel window for precise end-position tuning at commissioning. It delivers 402 N of push force at 0.5 MPa, making it suited for lighter-duty tasks.
This bore features a 12 mm SUS420J2 stainless steel rod and M10x1.25 rod thread. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-20 Is Used
Machine Setup Calibration
Dial in the exact 55-75 mm travel window during initial commissioning to perfectly strike a part without adding bulky external stoppers.
Product Size Changeover
Quickly readjust the retract end-position by up to 20 mm when running a different product size on the same line.
Light Assembly Clamping
Provides 402 N of push force at 0.5 MPa for holding small components, with fine end-stop tuning to prevent over-travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-20 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and a variable end-stop for product changeovers, rather than swapping a fixed-stroke SAI cylinder. If your application requires less force, step down is not an option from 32 mm as it is the smallest in this series, but stepping up to a 40 mm bore yields 628 N at 0.5 MPa for heavier loads. For an ISO 15552 replacement match, ensure you specify the PT tapered port thread, the SUS420J2 rod material, and the 20 mm adjustment range.
Because the nominal stroke is only 75 mm, side-load stress is minimal, but the 12 mm rod still requires external guiding if subjected to lateral forces. Remember that the rear adjuster and the variable air cushions only decelerate the travel end; they do not function as a lock. For true load-holding without live air, select an SAIL or BSAI cylinder 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 SAIJ32AX75-20 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from 75 mm down to 55 mm, creating a 20 mm adjustable travel window for fine-tuning without changing the cylinder.
It provides 402 N of push force and 345 N of pull force at 0.5 MPa. It uses a standard ISO 15552 mounting interface, supporting Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
