About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-75S
The AirTAC SAIJ32X210-75-S is a double-acting, adjustable-stroke ISO 15552 profile cylinder. A rear stopper screw lets you dial back the 210 mm nominal stroke by up to 75 mm, providing a usable travel window of 135-210 mm for precise end-position tuning at commissioning. 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 (option B) for corrosion resistance and includes a magnet for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the standard PT tapered port for this 32 mm bore is G1/8.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-75S Is Used
Machine Setup & Changeover
Fine-tune the 135-210 mm travel window during commissioning or product changeovers without physically swapping cylinders or adding external mechanical stops.
Variable End-Stop Positioning
Ideal for diverter gates or pushers on a conveyor line where the exact retraction end-position needs to be adjusted on the fly to accommodate different package sizes.
Corrosive Environment Actuation
The SUS304 stainless steel rod (option B) provides excellent corrosion resistance for light-duty manufacturing tasks in food processing or chemical packaging environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-75S the Right Cylinder?
Choose this 32 mm bore when your application requires around 402 N of thrust at 0.5 MPa. If your setup needs substantially more force, stepping up to the 40 mm bore yields 628 N of push force. The 75 mm adjustment range is ideal for product-size changeovers on a line, allowing you to reposition the end stop without swapping the cylinder or adding external stops. Remember that the rear adjuster is a travel stop, not a lock; the cylinder will not hold its load without live air. For true load-holding, consider an external rod lock or the SAIL series.
Because the 210 mm stroke exceeds 300 mm? No, but even at 210 mm, long unsupported strokes can induce side-load. Ensure you use an external guide to prevent rod binding. This SAIJ model uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552.
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 SAIJ32BX210-75S 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 the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear stopper screw allows you to shorten the effective stroke by up to 75 mm from the 210 mm nominal length, creating a usable travel window of 135-210 mm. The adjuster acts as a stop to set the travel end and is not a lock; it will not hold the load without live air pressure.
