About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-40
The AirTAC SAIJ32X185-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down to a 145-185 mm window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads. The rear stopper mechanism lets you fine-tune the retract end position during commissioning without adding external stops, while the standard variable air cushions decelerate the piston at both ends.

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 SAIJ32AX185-40 Is Used
Machine Changeover
Dial in the exact retract position within the 145-185 mm window when switching product sizes on a packaging line.
Commissioning Setup
Fine-tune the end-of-stroke stop during initial machine setup without fabricating or bolting on external physical spacers.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-40 the Right Cylinder?
The integrated rear adjuster acts purely as a travel stop, not a lock; the cylinder will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The 12 mm rod and M10x1.25 thread handle moderate side loads, but because the 185 mm stroke is substantial for this bore size, an external guide is recommended to prevent rod wear.
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 SAIJ32AX185-40 FAQ
The operational speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop that shortens the nominal 185 mm stroke, giving you a usable travel window of 145 to 185 mm. It only sets the end position and does not lock the load without air pressure.
