About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX25-10
The AirTAC SAIJ32X25-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position without adding external stops. With a nominal 25mm stroke and a 10mm adjustment range, it provides a usable travel window of 15-25mm for precise machine setup. In the compact 32mm bore class, it delivers 402N of push force at 0.5MPa, making it ideal for light-duty positioning tasks.
This model is configured with 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, although this specific SKU is built without a magnet for position sensing. You can fine-tune the retract end position directly at the rear screw, which acts as a travel stop rather than a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX25-10 Is Used
Precision Positioning
Dial in the exact 15-25mm travel window during machine commissioning to perfectly strike or push small components without re-engineering the fixture.
Product Changeovers
Quickly adjust the rear stop to accommodate varying part sizes on a high-mix assembly line, reducing downtime between production runs.
Light-Duty Clamping
Utilize the 402N of push force at 0.5MPa to hold small workpieces securely in place during light machining or bonding processes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX25-10 the Right Cylinder?
Select the 32mm bore when your application requires around 402N of push force at 0.5MPa; if you need greater clamping power, stepping up to the 40mm bore yields 628N. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops to accommodate product changeovers or precise commissioning without physically swapping the actuator. For this 25mm stroke, side-loading is minimal, but the M10x1.25 rod thread still requires alignment to prevent premature seal wear.
To replace this cylinder on an ISO 15552 footprint, match the 32mm bore, 25mm nominal stroke, 10mm adjustment, PT G1/8 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set. Because the SAIJ rear adjuster only sets the travel end and does not hold the load without live air pressure, you must use a SAIL or BSAI locking cylinder for any fail-safe load-holding requirements.
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 SAIJ32BX25-10 FAQ
At 0.5MPa operating pressure, the 32mm bore generates 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9MPa.
The rear adjuster screw lets you shorten the 25mm nominal stroke by up to 10mm, creating a 15-25mm usable travel window. This stopper sets the end position but does not lock the load without continuous air pressure.
