About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-50S
The AirTAC SAIJ32X230-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a 402N push force at 0.5 MPa. It features a SUS304 stainless steel rod and a PT tapered port. With a 230mm nominal stroke and a 50mm adjustment range, you gain a usable travel window of 180-230mm to perfectly dial in retract end positions during commissioning.
This adjustable stopper lets you trim the stroke without swapping the cylinder or adding external stops, which is invaluable during product changeovers. The extruded aluminum barrel includes sensor grooves on both sides for CMSE and DMSE switches. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for position holding, consider an external rod lock or the SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-50S Is Used
Machine Changeover
Quickly adjust the 180-230mm travel window to accommodate new product sizes on a packaging line without changing the cylinder.
End-Position Tuning
Fine-tune the retract stroke during initial commissioning to achieve exact positioning without adding external mechanical stops.
Variable Diverter Stops
Dial in the exact stop distance for varying package lengths on a conveyor system, utilizing the 50mm adjustment range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-50S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning, stepping up from smaller non-standard options if you need the 402N push force at 0.5 MPa. If your setup demands higher thrust, a 40mm bore provides 628N. The adjustable stroke is ideal for machine setups requiring variable end stops, whereas a fixed SAI cylinder is better for static, repeatable cycles. As an ISO 15552 replacement, match the 32mm bore, 230mm stroke, PT port, and -S magnet.
Because this unit features a 230mm stroke, ensure adequate guidance for the load to prevent excessive side loading on the M10x1.25 rod thread. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and CA options. For load-holding without live pressure, look to the BSAI clamp-lock series instead of relying on the air cushion or adjuster.
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 SAIJ32BX230-50S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides a push force of 402N and a pull force of 345N. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 50mm. This creates a usable travel window of 180-230mm from the 230mm nominal stroke, enabling fine-tuning of the end position without replacing the cylinder.
