About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-40S
The AirTAC SAIJ160X65-40-S is a double-acting, adjustable-stroke ISO 15552 profile cylinder. A rear stopper screw lets you trim the nominal 65mm stroke back by up to 40mm, creating a precise 25-65mm usable travel window for exact end-position tuning. In the 160mm bore class, it delivers 9425N of pull force at 0.5MPa and 14074N of push force at 0.7MPa.
This unit includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and carries the -S magnet option for position sensing. You can mount AirTAC CMSE reed or DMSE solid-state switches directly into the extruded aluminum barrel sensor grooves. The SAIJ mounting set omits FB, CA, CB, and CR brackets, utilizing a focused range of Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-40S Is Used
Machine Changeover
Dial in the 25-65mm travel window during product size transitions without physically replacing the cylinder or adding external shims.
Variable End Stops
Fine-tune the retract position on heavy machinery to accommodate varying material thicknesses on the fly.
Setup Commissioning
Use the 40mm rear adjustment screw to precisely set the end-of-stroke datum during initial machine commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-40S the Right Cylinder?
Choose this 160mm bore if your application requires heavy thrust that exceeds the 5734N pull force of a 125mm cylinder, but does not need the massive 15080N pull of a 200mm bore. The 40mm adjustment range is perfect for product changeovers, allowing you to shorten the stroke without swapping the cylinder or adding external stops. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series. This configuration features PT tapered ports and a -S magnet.
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.
