About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-20S
The AirTAC SAIJ100X950-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 930 to 950 mm. This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors.
Because the nominal 950 mm stroke falls within the standard maximum for this bore, it avoids made-to-order delays, yet the long travel distance necessitates careful alignment. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts strictly as a travel stop to fine-tune the retract position, not as a lock, meaning live air is required to maintain the load position.

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 SAIJ100BX950-20S Is Used
Variable End-Stop Machining
Dial in the exact retract distance within the 930-950 mm window during machine setup to accommodate different part depths without changing tooling.
Product Size Changeover
Quickly adjust the rear stopper on a packaging line to handle varying box lengths, ensuring precise positioning on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-20S the Right Cylinder?
Choose this adjustable-stroke cylinder when your setup requires exact end-position tuning on the fly, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, a plain SAIJ is insufficient—consider an SAIL or BSAI lock cylinder instead.
When specifying a replacement, match the 100 mm bore, 950 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option. Given the 950 mm stroke, the 25 mm rod and M20x1.5 thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading on the long unsupported travel. This model supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting styles.
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 SAIJ100BX950-20S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 930 to 950 mm. This stopper fine-tunes the retract end position but does not lock the load without live air pressure.
