About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-50
The AirTAC SAIJ100X950-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to trim the effective travel down by 50 mm, yielding a usable window of 900-950 mm for precise product changeovers. This unit omits a magnet, meaning position sensing is not equipped out of the box.
This model uses a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. The extruded aluminum barrel retains sensor grooves on both sides should you later require switches. The rear stopper acts purely as a travel end, so it does not hold the load without live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100BX950-50 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 900-950 mm window during machine setup to accommodate varying workpiece lengths without physical rebuilds.
Long-Stroke Positioning
Execute extended linear movements where the SUS304 rod provides corrosion resistance, adjusting the final stop precisely to match sensor targets.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-50 the Right Cylinder?
The 50 mm adjustment window is ideal for fine-tuning the retract position at commissioning without adding external stops or swapping cylinders. For load-holding without continuous air pressure, integrate an external rod lock or select a SAIL or BSAI model, as the SAIJ adjuster is not a locking mechanism.
With a 950 mm stroke, the 25 mm rod and M20x1.5 thread provide robust support, but an external guide is recommended to prevent side-load damage over long unsupported travels. This SKU is dimensionally interchangeable per ISO 15552 and uses a PT tapered port thread. Mounting options are restricted to Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ100BX950-50 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the nominal 950 mm stroke by up to 50 mm, creating a 900-950 mm travel window. It acts as a mechanical stop to fine-tune the end position and is not a lock.
