About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-50S
The AirTAC SAIJ100X325-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 275 to 325 mm. The integrated magnet enables position feedback via CMSE reed or DMSE electronic sensors.
Because the 325 mm stroke exceeds typical standard boundaries, an external guide is recommended to manage side loads on the long unsupported rod. The rear adjustment screw acts purely as a travel stop for end-position tuning, not a load-holding lock; maintaining position without live air requires a SAIL or BSAI variant.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-50S Is Used
Product Changeovers
Dial in the exact 275 to 325 mm end-stop during format size changes without physically replacing the actuator or bolting on external stops.
Diversion Arms
Adjust the stroke of conveyor sorting arms on the fly to accommodate varying package widths, using the SUS304 rod for durability in dynamic applications.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product-size changeovers on a packaging line, allowing operators to dial in the exact end-stop without swapping the cylinder or adding external stops. To match this ISO 15552 footprint, specify a 325 mm stroke, PT tapered ports, and the desired mounting from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ100 Adjustable Cylinder SAIJ100BX325-50S FAQ
When operating at 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the nominal 325 mm stroke by up to 50 mm, creating a usable travel window of 275 to 325 mm. It functions as a travel stop and does not hold the load without continuous air pressure.
