About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-40S
The AirTAC SAIJ100X950-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 910 to 950 mm. The integrated -S magnet enables position feedback via AirTAC CMSE reed or DMSE electronic sensors.
This model features a SUS304 stainless steel rod for superior corrosion resistance and features a G1/2 port. The rear adjuster acts purely as a mechanical stop to fine-tune the retract distance without adding external stops. It is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100BX950-40S Is Used
Product Changeovers
Dial in the 910-950 mm retract end-stop during format size changes on a packaging line without swapping out the entire actuator.
Long-Stroke Positioning
Move heavy jigs across a 950 mm span while using the rear screw to perfectly seat the load against a fixture at the end of travel.
Commissioning Calibration
Fine-tune the final resting position of a large press during machine setup, absorbing mechanical tolerances by trimming up to 40 mm of travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-40S the Right Cylinder?
The adjustable stroke is ideal for product-size changeovers on a line, functioning as a travel stop rather than a load lock; for dead-air load holding, consider an SAIL or BSAI cylinder. Because the 950 mm stroke is long, the 25 mm rod should be paired with an external guide to prevent excessive side-loading.
To match this exact configuration, specify a 100 mm bore, 950 mm stroke, 40 mm adjustment, PT tapered port threads, SUS304 rod material, and the -S magnet option.
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 SAIJ100BX950-40S FAQ
The rear adjuster screw lets you mechanically shorten the nominal 950 mm stroke by up to 40 mm, creating a 910-950 mm travel window. It acts as a physical stop and does not lock the load without live air pressure.
