About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-10S
The AirTAC SAIJ32X45-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a 402N push force at 0.5 MPa, making it suited for lighter-duty tasks. The integrated -S magnet supports position sensing via CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves.
This specific SKU features a 10mm adjustment mechanism, creating a usable travel window of 35-45mm from the 45mm nominal stroke. This built-in rear stopper allows for fine end-position tuning at commissioning without adding external stops. It features a SUS420J2 stainless steel rod and PT tapered port threads.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-10S Is Used
Machine Setup Tuning
Dial in the exact 35-45mm travel window during commissioning to perfect part ejection without physically swapping the cylinder.
Product Changeover
Adapt to slightly different product sizes on a packaging line by adjusting the rear stopper up to 10mm in seconds.
Variable End Stops
Achieve precise end-position control on light-duty assembly fixtures where external hard stops are impractical to mount.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-10S the Right Cylinder?
Choose this 32mm bore when a compact ISO 15552 footprint is needed but exact end-positioning is variable; step up to a 40mm bore if you require greater force (528N pull at 0.5 MPa). The adjustable stroke is ideal for product changeovers, letting you dial back the travel by up to 10mm on the fly. Remember that the rear adjuster functions strictly as a travel stop, not a lock, and it cannot hold a load without live air. For secure load-holding without continuous pressure, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 replacement exactly, verify the 45mm stroke, 10mm adjustment, PT G1/8 port, and the -S magnet option.
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 SAIJ32AX45-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides a push force of 402N and a pull force of 345N. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster acts as an external mechanical stop that lets you shorten the effective stroke from 45mm down to 35mm. It allows fine-tuning of the end position without replacing the cylinder.
