About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-10S
The AirTAC SAIJ32X55-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 45-55 mm usable travel window, letting you trim the 55 mm nominal stroke by up to 10 mm during machine setup. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant uses an SUS420J2 stainless steel rod for improved corrosion resistance and includes a built-in magnet for CMSE or DMSE sensors. The rear screw acts as a travel stop for fine end-position tuning, but it does not lock the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-10S Is Used
End-Position Tuning
Dial in the exact 45-55 mm travel window during commissioning to perfect pick-and-place movements without swapping cylinders.
Machine Changeover
Quickly adapt the retract end-stop when switching product sizes on a packaging line, saving setup time and tooling costs.
Light-Actuation Stops
Manage precise stops for 402 N push applications using the rear adjuster, ensuring repeatable end-of-stroke positioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX55-10S the Right Cylinder?
Select this 32 mm bore when you need precise end-stop tuning without external stops; for higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The PT tapered port is G1/8. To replace an ISO 15552 cylinder, match the 32 mm bore, 55 mm stroke, 10 mm adjustment, PT port, and -S magnet. Since the stroke is under 300 mm, side-load risks are minimal, but always guide unsupported loads.
Choose this adjustable-stroke model over a fixed SAI when product changeovers require slight travel tweaks. For load-holding without live pressure, use an external rod lock or explore the SAIL or BSAI series instead of relying on the rear adjuster.
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 SAIJ32AX55-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. Maximum thrust is 82 kgf at 1.0 MPa.
A rear screw stopper lets you shorten the 55 mm nominal stroke by up to 10 mm, creating a 45-55 mm travel window. The adjuster sets the end position but does not hold the load without live air.
