About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-30S
The AirTAC SAIJ100X325-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a durable SUS304 stainless steel rod and an integrated magnet for position sensing. The built-in rear stopper allows you to fine-tune the effective travel down from the 325mm nominal stroke, creating a precise 295-325mm usable window without requiring external stops.
This adjustable capability is ideal for product changeovers on packaging lines, letting you dial in the exact end position at commissioning. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Because the 325mm stroke is relatively long, the 25mm rod diameter provides robust support, though an external guide is still recommended for heavy lateral loads.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-30S Is Used
Product Changeovers
Dial in the 295-325mm stroke window during format changes on packaging lines, avoiding the need to physically swap cylinders for different carton sizes.
End-Position Tuning
Fine-tune the retract end-position at machine commissioning to perfect pressing or clamping depth without adding bulky external mechanical stops.
Heavy Payload Handling
Leverage the 3927N push force at 0.5 MPa to move heavy materials, relying on the 25mm SUS304 rod for reliable operation in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-30S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (2513N push at 0.5 MPa) lacks the thrust for your tooling, but a 125mm unit (6136N) would be excessive. The 30mm adjustment range is selected when you need a variable end-stop to accommodate minor product size differences on the fly, rather than swapping to a fixed-stroke SAI cylinder. Ensure your mounting choice uses the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
When replacing an ISO 15552 cylinder, match the 100mm bore, 325mm stroke, PT tapered port threads, and the -S magnet requirement. Remember that the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air. For dead-load holding, specify an SAIL pneumatic lock or an external rod lock.
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 SAIJ100 Adjustable Cylinder SAIJ100BX325-30S FAQ
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N. The operating pressure ranges from 0.15 to 1.0 MPa, and the standard speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 325mm nominal stroke by up to 30mm, resulting in a usable travel window of 295-325mm. It only sets the travel end and does not lock the load without continuous air pressure.
