About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-100S
The AirTAC SAIJ32X300-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 300 mm stroke that can be fine-tuned down by up to 100 mm, creating a precise 200-300 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups requiring exact end-position tuning.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while offering an adjustment range suited for high-mix production environments.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-100S Is Used
Product Changeovers
Dial in the 200-300 mm travel window during line format changes to accommodate different product lengths without mechanical rebuilds.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve precise seating, preventing damage to delicate components.
Variable Sorting
Adjust the stroke on the fly for diverting varying package sizes on a conveyor system, ensuring accurate physical placement.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-100S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with on-the-fly stroke trimming; step up to a 40 mm bore if your application requires 628 N. The 100 mm adjustment window is ideal for product changeovers, allowing you to shift the retract end-position without swapping the cylinder or adding external stops. Because the 300 mm stroke is relatively long for a 32 mm bore, ensure you use an external guide to prevent excessive side-loading on the 12 mm rod.
When specifying a replacement, confirm the 300 mm nominal stroke, 100 mm adjuster code, PT tapered port threads, and the -S magnet. The rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32AX300-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, providing a usable travel range of 200 to 300 mm. The adjuster is a mechanical stop that sets the end position, but it does not lock the load without continuous air pressure.
