About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-40S
The AirTAC SAIJ32X185-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the rear adjustment screw, you can trim the nominal 185mm stroke back by up to 40mm, creating a precise 145-185mm usable travel window for exact end-position tuning.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during product changeover. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports CMSE reed and DMSE electronic solid-state switches. It uses a PT tapered G1/8 port and variable air cushions at both ends to decelerate the load smoothly.

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 SAIJ32BX185-40S Is Used
End-Position Tuning
Dial in the exact 145 to 185mm travel distance during machine commissioning without machining external stopper blocks.
Product Changeover
Quickly adapt the stroke end-point on packaging lines when handling slightly different carton or product sizes.
Sensor Setup
Leverage the dual sensor grooves and -S magnet to precisely set CMSE or DMSE switch positions alongside the mechanical stop.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-40S the Right Cylinder?
The 40mm adjustment range is ideal for machine setups requiring variable end-stops without replacing hardware. Mounting options include the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop; for load-holding without live air, select an SAIL or BSAI cylinder. As a true ISO 15552 cylinder, it matches standard interface dimensions and requires a PT G1/8 port, M10x1.25 thread, and -S magnet for sensors.
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 SAIJ32BX185-40S FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective travel from the 185mm nominal stroke down to a minimum of 145mm. It sets the end position but does not lock the load without live air pressure.
