About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-50
The AirTAC SAIJ32X230-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 230 mm travel by up to 50 mm. This yields a usable positioning window of 180-230 mm, enabling fine end-position tuning at commissioning without swapping the hardware. In the 32 mm bore class, it generates 402 N of push force at 0.5 MPa and 345 N of pull force, making it suitable for lighter-duty tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE solid-state switches. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-50 Is Used
Variable End-Stop Tuning
Dial in the exact 180-230 mm travel distance during machine commissioning to accommodate varying material thicknesses without adding external physical stops.
Product Changeover
Quickly readjust the cylinder's end position on automated lines when switching between different product sizes, minimizing downtime between runs.
Corrosive Environments
Leverage the SUS304 stainless steel rod in light-duty testing or processing environments where standard carbon steel rods would be susceptible to rust.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-50 the Right Cylinder?
Choose this 32 mm bore when your application requires a maximum push force of 402 N at 0.5 MPa, which is a step down in thrust from the 40 mm bore that provides 628 N. The 50 mm adjustable range is ideal for machine setups requiring variable end-stops or frequent product changeovers, replacing the need for fixed-stroke SAI cylinders and external stop blocks. Because the stroke is 230 mm, ensure adequate guidance to prevent excessive side-loading on the 12 mm rod. To match this ISO 15552 footprint, specify the 32 mm bore, 230 mm stroke, 50 mm adjustment, PT port, and the desired mounting style from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ32BX230-50 FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke from its nominal 230 mm down to as little as 180 mm. This provides a 50 mm tuning window to perfectly set the end position without changing the cylinder itself.
At 0.5 MPa, it provides a push force of 402 N and a pull force of 345 N. At the maximum operating pressure of 1.0 MPa, the push force increases to 724 N.
