About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX20-10S
The AirTAC SAIJ32X20-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 20 mm stroke that can be dialed back by up to 10 mm, creating a 10-20 mm usable travel window for exact end-position tuning at commissioning. Delivering 402 N of push force at 0.5 MPa, it handles light-duty positioning with precision.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for direct feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX20-10S Is Used
Product Changeovers
Dial in the 10-20 mm travel window during format changes on packaging lines without physically swapping out the actuator.
End-Stop Calibration
Use the rear screw to precisely set the final retract position for delicate assembly tasks requiring 402 N of force.
Sensor-Equipped Sorting
Leverage the built-in magnet with DMSE electronic sensors for position feedback on small diverter mechanisms.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX20-10S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa within a very tight 10-20 mm travel window. If your setup needs less force, dropping to a smaller bore is advised, but stepping up to a 40 mm bore yields 628 N of thrust. The adjustable rear stopper is ideal for product changeovers, allowing you to fine-tune the end position without swapping the cylinder or adding external stops.
Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without continuous live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock or an external rod lock. When replacing an ISO 15552 cylinder, match the 32 mm bore, 20 mm stroke, 10 mm adjustment, PT G1/8 port, and the -S magnet requirement.
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 SAIJ32BX20-10S FAQ
It uses an external adjusting screw at the rear that shortens the effective stroke by up to 10 mm. This gives a usable travel window of 10-20 mm, allowing you to trim the retract end-position without adding external stops.
At 0.5 MPa operating pressure, it 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.
