About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-10S
The AirTAC SAIJ32X180-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 170-180 mm usable travel window, allowing you to dial back the 180 mm nominal stroke by up to 10 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet supports CMSE reed and DMSE electronic switches for precise position feedback.
This model uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the retract end position; it does not lock the load or hold position without live air pressure. For load-holding requirements without continuous air, consider an external pilot-operated check valve or the SAIL lock series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-10S Is Used
Machine Setup Tuning
Fine-tune the 170-180 mm travel window during initial commissioning to perfectly align a pushing face without machining external stopper blocks.
Product Changeovers
Quickly adjust the retract end-position by up to 10 mm on a packaging line when switching between slightly different product sizes.
Light-Force Testing
Leverage the 402 N push force and SUS420J2 stainless steel rod for controlled, repeatable actuation in light-duty laboratory or testing fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and on-the-fly end-position tuning. If your setup needs less force, a smaller bore is preferable, while heavier loads require stepping up to the 40 mm bore, which provides 628 N. The adjustable stroke is ideal for product changeovers where exact end-stops vary slightly, eliminating the need to physically swap cylinders or bolt on external stopper blocks.
To match this ISO 15552 replacement, verify the 32 mm bore, 180 mm stroke, 10 mm adjustment range, PT port threads, and the -S magnet option. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for any stroke of 300 mm or more, an external guide is recommended to prevent rod bending. SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32AX180-10S FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates a push force of 402 N and a pull force of 345 N. It can deliver up to 724 N of push force at 0.9 MPa.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the 180 mm nominal stroke by up to 10 mm, creating a 170-180 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
