About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-20S
The AirTAC SAIJ32X80-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 80mm nominal stroke by up to 20mm. This yields a precise 60-80mm usable travel window, perfect for fine-tuning end positions at commissioning without adding external stops. It delivers a 402N push force at 0.5 MPa and 724N at 0.9 MPa, matching standard SAI output in a compact 32mm bore.
Built for sensing and durability, this variant includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the extruded aluminum barrel's dual sensor grooves. It features a SUS304 stainless steel rod for corrosion resistance and utilizes PT tapered ports. The rear adjuster acts purely as a travel stop for deceleration; 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 SAIJ32BX80-20S Is Used
End-Position Tuning
Dial in the exact 60-80mm travel distance during machine commissioning to perfect product placement without swapping physical cylinders.
Product Changeover
Quickly adapt the stroke length on packaging lines when running different package sizes, using the rear screw to set new endpoints.
Adjustable Clamping
Apply up to 724N of clamping force at 0.9 MPa while fine-tuning the travel to accommodate varying workpiece thicknesses.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-20S the Right Cylinder?
Select this 32mm bore adjustable cylinder when your machine setup requires variable end-stops or frequent product-size changeovers, rather than relying on a fixed-stroke SAI model. If your application requires greater thrust, stepping up to the 40mm bore yields 528N pull force at 0.5 MPa. Conversely, this 32mm unit is ideal when 345N pull force is sufficient but adjustability is paramount. To guarantee an exact ISO 15552 replacement, match the 80mm stroke, 20mm adjustment, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, and the -S magnet requirement.

- ✓ 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 SAIJ32BX80-20S FAQ
At 0.5 MPa it provides 402N push and 345N pull force. At 0.9 MPa the push force increases to 724N.
The rear adjuster allows you to shorten the 80mm nominal stroke by up to 20mm, creating a 60-80mm usable travel window. It functions as an end stop, not a lock.
