About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-50
The AirTAC SAIJ32X175-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, designed to fine-tune end positions without adding external stops. It provides a usable travel window of 125 to 175 mm, allowing precise calibration during machine commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
Equipped with a SUS420J2 stainless steel rod (code A), this 32 mm bore model delivers 402 N of push force and 345 N of pull force at 0.5 MPa. It features PT tapered port threads (G1/8) and variable air cushions at both ends to manage impact deceleration across its 30-800 mm/s operating speed range.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-50 Is Used
End-Position Calibration
Dial in the exact retract distance within the 125-175 mm window during machine setup to accommodate varying material thicknesses without swapping hardware.
Product Changeover
Quickly readjust the stroke stopper on packaging lines when switching to a different package size, minimizing downtime between production runs.
Assembly Positioning
Fine-tune the approach distance of a small pneumatic press, relying on the 12 mm rod and M10x1.25 thread to handle moderate side loads accurately.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-50 the Right Cylinder?
Select this 32 mm bore cylinder when an application requires 402 N of push force at 0.5 MPa, stepping up to the 40 mm bore yields 628 N if your load demands increase. The adjustable stroke is chosen over a fixed SAI cylinder when you need a variable end-stop for setup calibration, whereas the SAIL or BSAI series should be specified if the mechanism must hold a load without continuous live air pressure. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders such as the Festo DSBC or SMC C95. Ensure your replacement matches the 32 mm bore, 175 mm stroke, 50 mm adjustment, PT G1/8 port, and the required mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ32AX175-50 FAQ
The rear adjuster acts as a mechanical stopper that shortens the effective stroke by up to 50 mm. This provides a usable travel window of 125 to 175 mm, allowing you to set the exact end position at commissioning. The adjuster and air cushions only manage travel ends and do not hold the load without live air.
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. If higher pressure is available, it can reach up to 724 N of push force at 0.9 MPa.
