About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-50S
It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. With a 750 mm nominal stroke and a 50 mm adjustment range, you can fine-tune the effective travel to any point within a 700-750 mm window during commissioning.
This adjustable stopper lets you dial in exact end positions without swapping the cylinder or adding external stops. The PT tapered port threads ensure a tight pneumatic seal, while the extruded aluminum barrel maintains standard ISO 15552 mounting dimensions. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

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 SAIJ100BX750-50S Is Used
Variable End-Stop Machining
Fine-tune the 700-750 mm travel window to accommodate different part lengths on a machining line without physically swapping out actuators.
Product Changeover Diverters
Quickly adjust the retract position by up to 50 mm during packaging line format changes to handle varying box dimensions on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-50S the Right Cylinder?
The 50 mm adjustment window is ideal for product changeovers, allowing you to shift the end-of-stroke position dynamically rather than relying on a fixed-stroke SAI cylinder. To match this exact ISO 15552 footprint, specify a 100 mm bore, 750 mm stroke, 50 mm adjustment, PT ports, SUS304 (B) rod, and the -S magnet option.
Because the stroke is 750 mm, the 25 mm rod diameter needs external guidance to prevent excessive side-loading on the seals. For applications requiring the load to be held mechanically without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ100BX750-50S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 750 mm nominal stroke by up to 50 mm. This creates a usable travel window of 700-750 mm for fine-tuning end positions at commissioning.
