About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-40S
The AirTAC SAIJ32X95-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 55 to 95 mm without external stops. It delivers 402N of push force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks.
This specific SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for position sensing. You can mount AirTAC CMSE reed or DMSE electronic solid-state switches directly into the sensor grooves extruded on both sides of the aluminum barrel.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-40S Is Used
Machine Setup Calibration
Dial in the exact end-of-stroke position within the 55-95 mm window during initial commissioning without machining custom spacers.
Product Size Changeovers
Quickly adapt the cylinder's stroke on packaging lines when handling different carton lengths or product widths.
Sensor Positioning
Leverage the dual sensor grooves and built-in magnet to mount CMSE or DMSE switches for precise adjustable end-stop feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-40S the Right Cylinder?
Choose this 32mm bore when your application requires precise end-position tuning during commissioning or product changeovers, stepping up from smaller actuators while keeping the footprint compact. If your setup needs greater thrust, the neighboring 40mm bore provides 628N of push force at 0.5 MPa.
Because the stroke is 95 mm, side loads remain manageable, but always guide the load externally for optimal seal life. The rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure; for fail-safe load holding, select an AirTAC SAIL or BSAI series cylinder. This adjustable model uses a PT tapered port and supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), ensuring dimensionally interchangeable per ISO 15552 compatibility.
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 SAIJ32BX95-40S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum of 82 kgf at 1.0 MPa.
The rear adjusting screw allows you to shorten the 95mm nominal stroke by up to 40mm, creating a usable travel window of 55 to 95mm. This stopper decelerates the travel end but does not lock the load without live air pressure.
