About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-100
Its integrated rear stopper allows you to trim the effective travel, creating an 850-950mm usable window for precise end-position tuning without swapping out the entire actuator. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback integration.
This configuration utilizes a SUS304 stainless steel rod (option B) for superior corrosion resistance and ships with PT tapered port threads. Because the 950mm stroke is substantial, the 25mm rod diameter and M20x1.5 rod thread provide a robust interface, though an external guide is strongly recommended to manage side loads over this long travel distance.

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 SAIJ100BX950-100 Is Used
Variable End-Stop Positioning
Ideal for diverter gates or push-off stations where the retract distance must be fine-tuned on the fly within the 850-950mm window to accommodate different package depths.
Machine Changeover Setup
Allows production lines to switch between product sizes rapidly by turning the rear adjuster screw to set a new physical stop, eliminating the need to install manual mechanical spacers.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-100 the Right Cylinder?
The 100mm adjustment range is ideal for production lines running mixed product sizes, allowing operators to dial in the exact retract stop during changeovers rather than machining custom external spacers. If your setup demands holding a load statically without continuous air pressure, note that this standard SAIJ adjuster acts only as a travel stop; you would need to specify a SAIL or BSAI locking cylinder instead.
For a true ISO 15552 replacement match, verify the 100mm bore, 950mm stroke, PT G1/2 port, and your required mounting hardware from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. This specific SKU does not include a magnet, so it will not directly support AirTAC CMSE or DMSE sensors without modification.
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 SAIJ100BX950-100 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the nominal 950mm stroke by up to 100mm. This creates an adjustable travel window between 850mm and 950mm, which is set during commissioning. Note that this screw is a stop, not a lock, and will not hold the load without live air pressure.
The pull force at 0.5 MPa is 3681N due to the rod displacement.
