About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-100S
By integrating a 100mm adjustment mechanism, this model creates an 850-950mm usable travel window, allowing precise end-position tuning without swapping out the entire actuator. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE electronic solid-state switches for reliable position feedback.
Configured for demanding environments, this unit utilizes a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The 25mm rod diameter and M20x1.5 rod thread provide excellent structural rigidity, though the 950mm stroke length necessitates an external guide to prevent excessive side-loading on the piston. Variable air cushions at both ends absorb kinetic energy, but the rear adjuster acts strictly as a travel stop rather than a load-holding lock.

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 SAIJ100BX950-100S Is Used
Variable End-Stop Tuning
Dial in the retraction distance anywhere between 850mm and 950mm during machine commissioning to perfectly match product dimensions without changing the actuator.
Product-Size Changeovers
Quickly adapt automated lines to new part lengths by rotating the rear adjuster screw, reducing downtime between production runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX950-100S the Right Cylinder?
The 100mm adjustment range is ideal for dialing in exact retraction distances during commissioning, entirely avoiding the need to bolt on external physical stops. To match this exact configuration for an ISO 15552 replacement, verify the 100mm bore, 950mm stroke, PT port threads, and the -S magnet option.
Because the 950mm stroke exceeds typical compact dimensions, you must support the load with an external linear guide to protect the rod from bending. Furthermore, if your application requires the load to be held in place without live air pressure, the rear adjuster cannot serve as a brake; you should instead utilize a SAIL pneumatic lock cylinder, a BSAI clamp-lock variant, or an external pilot-operated check valve. This SAIJ model uses the standard SAIJ mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100BX950-100S FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 850-950mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
At a maximum operating pressure of 1.0 MPa, the push force increases to 801kgf.
