About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-75S
The AirTAC SAIJ100X950-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position without adding external stops. With a 950 mm nominal stroke and a 75 mm adjustment range, it provides a usable travel window of 875 to 950 mm for precise product changeovers. It delivers robust thrust, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing. The extruded aluminum barrel integrates dual-side sensor grooves compatible with CMSE reed and DMSE electronic solid-state switches. It supports a subset of ISO 15552 mounts: 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 SAIJ100AX950-75S Is Used
Product Size Changeovers
Dial in the exact end-position from 875 to 950 mm during line changeovers without physically swapping out the entire actuator assembly.
Long-Stroke Diverter
Pushes or diverts heavy pallets over a long travel distance, using the rear stopper to tune the extended position to match varying pallet widths.
Adjustable Pressing Station
Applies up to 7068 N of pressing force at 0.9 MPa, allowing operators to micro-adjust the stroke end to accommodate different material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-75S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires heavy thrust (up to 801 kgf at 1.0 MPa) alongside variable end-stops. The adjustable rear screw is strictly a travel stop; it does not hold the load without live air pressure. For true load-holding without continuous air, use an external rod lock, pilot-operated check valve, or AirTAC SAIL/BSAI series cylinders.
When ordering an ISO 15552 replacement, match the 100 mm bore, 950 mm stroke, 75 mm adjustment, PT tapered port threads, and -S magnet. Because the 950 mm stroke is long and unsupported, adding an external guide rail is critical to prevent rod side-loading and premature seal wear.
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 SAIJ100AX950-75S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 75 mm. This creates an adjustable window between 875 and 950 mm without changing the cylinder's physical mounting.
