About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-40S
The AirTAC SAIJ32X160-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 120-160 mm usable travel window from its 160 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it provides precise end-position tuning without external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and PT tapered ports for a tight seal. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position at commissioning; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-40S Is Used
Product Changeover
Dial in the 120-160 mm travel window during line size changes without physically replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract stroke at commissioning to absorb minor mechanical tolerances and achieve exact positioning of the 12 mm rod.
Corrosive Environments
Leverage the SUS304 stainless steel rod for light-duty testing or packaging tasks where moisture resistance is critical to component longevity.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-40S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa and on-the-fly end-stop adjustments during machine changeover. If your application requires less force, stepping down is not an option in this footprint, but stepping up to a 40 mm bore yields 628 N of push force. The adjustable stroke is ideal for dialing in exact positioning without swapping cylinders, unlike a fixed-stroke SAI model.
To match this ISO 15552 replacement exactly, use a 32 mm bore, 160 mm stroke, 40 mm adjustment range, PT port threads, and a -S magnet for CMSE or DMSE sensors. The 12 mm rod and M10x1.25 thread handle moderate side loads, but because the stroke is 160 mm, ensure proper guidance to prevent rod binding. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ32BX160-40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 160 mm nominal stroke by up to 40 mm, creating a 120-160 mm travel window. It only sets the end position and does not lock the load without live air pressure.
