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. 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.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-40S the Right Cylinder?
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.
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 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.
