Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-10S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 400mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-10S
The AirTAC SAIJ32X400-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 390-400 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning without swapping the cylinder or bolting on external stops. Featuring a 32 mm bore, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant includes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and ships with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 porting for this bore size. The rear adjuster acts purely as a travel stop, meaning it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-10S Is Used
End-Position Tuning
Dial in the exact 390-400 mm retract distance during machine commissioning to perfect product seating without adding external stops.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a slightly different package size.
Assembly Fixtures
Use the 402 N push force to press small components, relying on the rear screw to fine-tune the final pressing depth.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-10S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when you need fine end-position tuning of a 400 mm stroke, delivering 402 N push force at 0.5 MPa. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. Conversely, if you need less force, the SAIJ series does not offer a smaller standard ISO 15552 bore. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed-stroke SAI cylinder is preferred when the end position never changes.
Because the 400 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to support the load and prevent excessive side-loading on the 12 mm rod. To replace an ISO 15552 cylinder, match the 32 mm bore, 400 mm stroke, 10 mm adjustment, PT port threads, and the -S magnet. For load-holding without live air, the rear stopper here is not a lock; you would need an external rod lock or a SAIL pneumatic lock 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 SAIJ32AX400-10S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 400 mm nominal stroke by up to 10 mm. This provides a usable travel window of 390-400 mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ32X400-10-S generates 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 724 N.
