About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-50S
The AirTAC SAIJ32X225-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 175 to 225 mm, allowing you to dial back the 225 mm nominal stroke by up to 50 mm during machine commissioning. It delivers a 0.5 MPa push force of 402 N and a pull force of 345 N.
This SKU features a SUS420J2 stainless steel rod for enhanced durability against minor corrosion and wear. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The PT tapered port threads are G1/8, and the standard speed range spans 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-50S Is Used
Machine Changeover
Fine-tune the retract end position on the fly when switching between product sizes on a packaging line, utilizing the 175-225 mm adjustable travel window.
Variable End Stops
Dial in the exact clamping depth during assembly commissioning without adding external mechanical stops or replacing the entire cylinder.
Light Payload Positioning
Drive small actuators with a 402 N push force at 0.5 MPa, leveraging the 30-800 mm/s speed range for rapid cycling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-50S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning without swapping out physical components. Compared to the neighboring 40 mm bore that yields 628 N of push force at 0.5 MPa, this 32 mm unit is optimal for lighter payloads where exact variable end-stops are critical. If your process demands holding a load without live air pressure, note that the rear adjuster acts only as a travel stop; you should instead select an SAIL air-released lock or BSAI clamp-lock cylinder.
For ISO 15552 replacement matching, specify a 32 mm bore, 225 mm stroke, 50 mm adjustment range, PT G1/8 port, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 225 mm stroke is relatively long for a 32 mm rod, external guidance is recommended to prevent excessive side-loading on the rod thread.

- ✓ 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 SAIJ32AX225-50S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 50 mm. This creates a usable travel window of 175 to 225 mm, allowing precise retract end-position tuning without replacing the cylinder.
At a 0.5 MPa operating pressure, it provides a push force of 402 N and a pull force of 345 N. The maximum push force reaches 724 N at 0.9 MPa.
