About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX250-30
The AirTAC SAIJ100X250-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, enabling you to fine-tune the end position during commissioning. With a nominal 250 mm stroke and a 30 mm adjustment range, it provides a usable travel window of 220 to 250 mm. This allows you to dial in the exact retract distance without swapping out the hardware or adding external stops.
This model is equipped with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic sensors directly. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and relies on adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIJ100BX250-30 Is Used
Machine Setup & Changeover
Fine-tune the 220 to 250 mm retract window during line changeovers to accommodate different product sizes without replacing the cylinder.
Variable End-Stop Tuning
Dial in the exact end position during commissioning to perfect the mechanical timing of a multi-stage assembly process.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX250-30 the Right Cylinder?
The adjustable stroke is ideal for machinery requiring variable end-stops or frequent product changeovers. At 250 mm stroke, the 25 mm rod diameter provides a sturdy interface, but for long unsupported loads, you should incorporate an external guide to prevent excessive side-loading.
This cylinder is dimensionally interchangeable with ISO 15552 cylinders. It is double-acting and uses PT ports. Note that the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the load without live air. For true position holding without continuous pressure, consider an AirTAC SAIL or BSAI model, or use 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 SAIJ100BX250-30 FAQ
The rear adjuster screw allows you to shorten the effective travel from the nominal 250 mm down to as little as 220 mm. This stop mechanism lets you fine-tune the retract end position without adding external stops, though it does not lock the load without live air.
