About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-40S
The AirTAC SAIJ32X45-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to a 5-45 mm range from its 45 mm nominal stroke. Built with a SUS304 stainless steel rod and a PT tapered port thread, it delivers 402N of push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a magnet for position detection, this model supports AirTAC CMSE reed and DMSE solid-state sensors. The rear adjuster acts purely as a mechanical stop to set the end position without needing external stops, but it does not lock the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-40S Is Used
Product Changeover
Quickly dial in the end-stop from 45 mm down to 5 mm when switching between product sizes on the same conveyor line.
Commissioning Setup
Fine-tune the exact retract position during machine setup without machining custom external spacers.
Variable End Stops
Set precise mechanical travel limits for small parts pushing tasks requiring up to 402N of force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-40S the Right Cylinder?
Choose this 32 mm bore when your application requires precise end-position tuning during commissioning or product changeovers, offering a 402N push force at 0.5 MPa. If your setup needs less force, stepping down to a smaller bore is an option, while moving up to a 40 mm bore provides 628N of push force. Unlike a fixed-stroke SAI cylinder, this model's rear screw allows you to dial back the stroke by up to 40 mm without swapping components.
This configuration includes a -S magnet for CMSE or DMSE sensors and a SUS304 rod for enhanced corrosion resistance. It uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552. Remember that the air cushion and adjuster only decelerate the travel end; they do not function as a brake or lock.

- ✓ 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 SAIJ32BX45-40S FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 40 mm, providing a usable travel window of 5 to 45 mm. The adjuster acts as a mechanical stop to set the end position and does not hold the load without live air pressure.
At an operating pressure of 0.5 MPa, the SAIJ32X45-40-S provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
