About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-100
The AirTAC SAIJ32X230-100 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a generous 130-230 mm usable travel window, allowing you to dial back the nominal 230 mm stroke by up to 100 mm during commissioning. This built-in adjustability eliminates the need to swap out physical cylinders or add bulky external stops when refining end positions. Delivering 563 N of push force at 0.7 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threading.
Because the stroke extends to 230 mm on a 12 mm rod, the piston is subject to increased bending moments, meaning an external guide rail is strongly recommended to prevent side-load damage. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific unit lacks a magnet, the grooves remain ready for future automation upgrades. The rear adjuster acts strictly as a travel stop to set deceleration, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-100 Is Used
Product Changeover
Dial in the exact end-stop for different package lengths on a single machine without physically swapping cylinders or adding external shims.
Assembly Fixtures
Fine-tune the 130-230 mm travel window during initial commissioning to perfect the pressing force and position of delicate components.
Laboratory Testing
Leverage the SUS304 stainless steel rod and adjustable stroke for repeatable material testing across varying sample sizes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-100 the Right Cylinder?
Choose this 32 mm bore when your application requires 563 N of push force at 0.7 MPa but demands highly variable end-stop positioning. If your setup needs less force and a smaller footprint, the 40 mm bore offers 879 N; conversely, stepping down is not an option here as 32 mm is the smallest in the series. The massive 100 mm adjustment range makes this specific SKU ideal for packaging lines or testing fixtures where product sizes change frequently. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets. For a direct ISO 15552 replacement, match the 32 mm bore, 230 mm stroke, PT port, and SUS304 rod material.
If your process requires the load to be held in place without continuous live air pressure, note that the SAIJ rear adjuster and air cushions function only as travel stops, not as brakes. For true pneumatic locking, you would need to step up to an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder, or integrate an external pilot-operated check valve.

- ✓ 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 SAIJ32BX230-100 FAQ
This 32 mm bore cylinder provides 402 N of push force at 0.5 MPa and 563 N at 0.7 MPa, with a pull force of 345 N at 0.5 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 230 mm down to as little as 130 mm. It only sets the travel end and does not hold the load without live air pressure.
