About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-30
The AirTAC SAIJ32X375-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 375mm nominal stroke that can be fine-tuned backward by up to 30mm, creating a usable travel window of 345-375mm. In this configuration, the piston rod uses SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the fluid ports are PT tapered threads.
Delivering 402N of push force and 345N of pull force at 0.5MPa, it operates at speeds between 30-800mm/s. The defining benefit is on-the-fly end-position tuning during commissioning or product changeover, letting you dial in the exact retract stop without swapping the cylinder or bolting on external hardware. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-30 Is Used
Variable End-Stop Setup
Dial in the exact retract distance between 345mm and 375mm during machine commissioning to accommodate varying material thicknesses without changing hardware.
Product Changeover
Quickly adjust the stroke stop on the fly when switching a packaging line to a different carton size, saving downtime versus physically replacing cylinders.
Precision Forming
Fine-tune the bottoming position of a small pressing or clamping task, relying on the 402N push force at 0.5MPa to execute consistent light-duty work.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-30 the Right Cylinder?
Choose this 32mm bore adjustable-stroke cylinder when your application requires precise retract positioning that might vary slightly between product runs, making a fixed-stroke SAI cylinder less practical. If your process needs more thrust, stepping up to the 40mm bore yields 628N of push force at 0.5MPa.
Because the 375mm stroke is relatively long for a 32mm rod, an external guide is recommended to prevent excessive side loading and premature seal wear. The rear adjuster acts strictly as a travel stop and works with the variable air cushions to decelerate the load; it does not hold the load without live air. For true load-holding without continuous pressure, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32AX375-30 FAQ
At a 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7MPa, the push force increases to 563N.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 30mm. This creates a usable travel window of 345-375mm from the 375mm nominal stroke, allowing precise end-position tuning without adding external stops.
