About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-10S
It features a 950mm nominal stroke that can be fine-tuned down by up to 10mm, creating a precise 940-950mm usable travel window. This built-in adjustability allows you to dial in the retract end-position during commissioning without swapping out the entire cylinder or adding external stopper blocks.
This specific SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual-side sensor grooves of the extruded aluminum barrel. The cylinder operates at 30-800mm/s and utilizes PT tapered port threads (G1/2) for reliable pneumatic connections.

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 SAIJ100BX950-10S Is Used
Precision End-Stop Tuning
Micro-adjust the retract position by up to 10mm during machine commissioning to achieve exact part placement without machining new hard stops.
Product Changeover
Quickly adapt a 950mm stroke length to accommodate slightly different product sizes on a packaging line by dialing the rear adjuster within the 940-950mm window.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-10S the Right Cylinder?
The 10mm adjustable window is ideal for applications requiring micro-adjustments to the retract position during product changeovers. Because the stroke is 950mm, the M20x1.5 rod is highly susceptible to side-loading; an external guide mechanism is strongly recommended to prevent premature seal wear and rod binding.
For ISO 15552 dimensional interchangeability, match these exact parameters: 100mm bore, 950mm stroke, 10mm adjustment range, PT G1/2 port, and the -S magnet. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
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 SAIJ100BX950-10S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 950mm nominal stroke by up to 10mm, yielding a 940-950mm travel window. It sets the end position but does not lock the load without continuous air pressure.
