About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-50
The AirTAC SAIJ32X225-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 225 mm stroke that can be dialed back by up to 50 mm, creating a precise 175-225 mm usable travel window for commissioning without external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches later if position detection becomes necessary.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-50 Is Used
Product Changeovers
Dial in the 175-225 mm travel window during format size changes on a packaging line, avoiding the need to physically swap out the entire cylinder.
Commissioning Fine-Tune
Precisely set the retract end-position during machine setup, using the rear stopper to absorb minor mechanical deviations without external shims.
Corrosive Assembly Tasks
Leverage the SUS304 stainless steel rod for light-duty pushing tasks in environments where standard carbon steel rods would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-50 the Right Cylinder?
Choose this 32 mm bore when your application requires roughly 402 N of thrust at 0.5 MPa; stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N if your payload increases. The 50 mm adjustment range is ideal for product changeovers, letting you fine-tune the retract end position on the fly instead of physically swapping cylinders. The rear adjuster acts purely as a travel stop and does not hold the load without live air—consider an AirTAC SAIL or BSAI cylinder if your cycle demands true load-holding without pressure.
To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 225 mm stroke, 50 mm adjustment, PT G1/8 port, and your desired mounting bracket from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Since the 225 mm stroke is relatively short for this bore, side-load risks are minimal, but always ensure the M10x1.25 rod thread is aligned with your load coupling.
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 SAIJ32BX225-50 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At a maximum 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 225 mm down to as little as 175 mm. It only sets the travel end point and does not lock the load without continuous air pressure.
