About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-10
The AirTAC SAIJ32X45-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and uses a PT G1/8 port. The integrated rear stopper allows you to fine-tune the effective travel down to 35 mm from the 45 mm nominal stroke, giving you a 35-45 mm usable window for precise end-position tuning during commissioning.
This 32 mm bore model is equipped with a SUS420J2 stainless steel piston rod for enhanced durability against minor nicks and corrosion. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic solid-state switches. Mounting options include the standard SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-10 Is Used
Precision End-Stop Tuning
Dial in the exact retraction point within the 35-45 mm window during machine setup to accommodate minor dimensional variations in parts.
Product Changeover
Quickly adjust the stroke length on the fly when switching between slightly different product sizes on a packaging line.
Fixture Calibration
Fine-tune the clamping position on small pneumatic fixtures without disassembling the cylinder or adding spacer blocks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-10 the Right Cylinder?
Select this 32 mm bore adjustable cylinder when your application requires exact end-position calibration without adding external mechanical stops. It delivers a 345N pull force at 0.5 MPa. If your process needs greater clamping power, stepping up to the 40 mm bore yields a 528N pull force. The rear adjuster acts purely as a travel stop and does not lock the load; for position holding without live air pressure, consider the SAIL or BSAI series.
When specifying a drop-in ISO 15552 replacement, verify the 45 mm stroke, the 10 mm adjustment range, PT tapered port threads, and the SUS420J2 rod material. Because the stroke is under 300 mm, side-load stress is minimal, though the 12 mm rod diameter still requires standard alignment during installation.
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 SAIJ32AX45-10 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the stroke by up to 10 mm. This provides a usable travel window of 35-45 mm. It only sets the end position and does not hold the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ32X45-10 provides a push force of 402N and a pull force of 345N. It can deliver up to 724N push force at 0.9 MPa.
