About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-75S
The AirTAC SAIJ100X950-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows precise end-position tuning during commissioning without swapping hardware.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for CMSE reed or DMSE electronic solid-state sensors. The extruded aluminum barrel carries sensor grooves on both sides, and the M20x1.5 rod thread handles high side loads. It uses PT tapered ports sized at G1/2 and operates at speeds of 30-800mm/s.

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 SAIJ100BX950-75S Is Used
Variable End-Stop Setup
Dial in the exact retraction point within the 875-950mm window during machine commissioning without adding external physical stops.
Product Size Changeovers
Quickly adapt the stroke length on automated lines processing different sized parts by turning the rear adjuster screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-75S the Right Cylinder?
Select this 100mm bore cylinder when an application requires substantial thrust—stepping down to a 63mm bore drops the 0.5MPa push force to 1559N, while moving up to 125mm increases it to 6136N. Choose the SAIJ adjustable-stroke design over a fixed SAI when you need variable end-stops for product changeovers. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air, so use a SAIL or BSAI lock for dead-air positioning. Because the 950mm stroke is long and unsupported, an external guide is recommended to manage side loads. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ100BX950-75S FAQ
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this model, the 950mm nominal stroke can be trimmed back by up to 75mm, creating a usable travel window of 875-950mm. It is a travel stop, not a lock, and cannot hold a load without live air pressure.
At the maximum 1.0MPa pressure, the push force reaches 801kgf.
