About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-20S
The AirTAC SAIJ32X230-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 210 to 230 mm, allowing you to dial back the nominal 230 mm stroke by up to 20 mm during commissioning without adding external stops. With a 32 mm bore, 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 for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to fine-tune end positions, meaning it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-20S Is Used
Machine Changeover
Fine-tune the 210-230 mm stroke window on the fly during product size changes without physically swapping cylinders or bolting on external stoppers.
End-Stop Calibration
Perfect for dialing in exact retracted positions during initial commissioning, ensuring precise tooling alignment using the rear adjusting screw.
Corrosive Testing
The SUS304 stainless steel rod handles light side loads and provides necessary corrosion resistance for test fixtures or environments with moisture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-20S the Right Cylinder?
Choose this 32 mm bore unit when your application requires 402 N of thrust at 0.5 MPa and precise end-position tuning. If you need more force, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. The adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, replacing the need to swap a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as this cylinder relies on live air. When replacing an ISO 15552 cylinder, match the 32 mm bore, 230 mm nominal stroke, 20 mm adjustment, PT G1/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface.
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 SAIJ32BX230-20S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 230 mm down to 210 mm. This creates a 20 mm adjustable window for fine-tuning the retract end position at commissioning, but it acts only as a stop and does not lock the load.
