About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-10S
The AirTAC SAIJ100X325-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to trim the effective travel back by up to 10 mm. This yields a usable end-position window of 315 to 325 mm, letting you dial in the exact retract distance without adding bulky external stops. It delivers robust thrust, providing 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the unit uses a G1/2 port. Because the 325 mm stroke is relatively long, an external guide is recommended to prevent excessive side-loading on the rod thread.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-10S Is Used
Machine Changeover
Dial in the retract stop from 315 to 325 mm to accommodate different product lengths on the same line without swapping out the entire cylinder.
End-Position Tuning
Fine-tune the final retract position during initial commissioning to compensate for mechanical wear or sensor placement variations.
Variable Discharge Stops
Adjust the physical backstop distance on a conveyor sorting system to handle varying package sizes accurately.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-10S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (delivering 2182 N push at 0.7 MPa) is insufficient for your load, but a 125 mm bore is overkill. The adjustable stroke is ideal for machine setups requiring fine end-position tuning during commissioning or product changeover, rather than relying on a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL/BSAI series. This model is dimensionally interchangeable per ISO 15552 and features PT tapered ports, a Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set, and a -S magnet.
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 SAIJ100BX325-10S FAQ
This 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 325 mm stroke by up to 10 mm, providing an adjustable travel window of 315 to 325 mm. It is a stop, not a lock, and requires live air to maintain position.
