About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-75S
The AirTAC SAIJ100X85-75-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, equipped with a SUS420J2 stainless steel rod and a magnet for position sensing. The 75 mm adjustment screw on this 85 mm nominal stroke creates a highly versatile 10 to 85 mm usable travel window, allowing you to dial in exact retract positions without adding external stops.
This adjustable-stroke model uses a PT tapered G1/2 port and operates at speeds from 30 to 800 mm/s. It supports AirTAC CMSE reed and DMSE electronic sensors via its dual-side sensor grooves. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure; for dead-stop holding, consider a SAIL or BSAI variant.

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 SAIJ100AX85-75S Is Used
Product Changeover
Quickly reposition the retract end-stop within the 10-85 mm window to accommodate varying package sizes on a packaging line without swapping cylinders.
End-Position Tuning
Fine-tune the final resting position during machine commissioning to achieve exact alignment, using the 75 mm rear adjuster rather than machining spacers.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-75S the Right Cylinder?
The 10-85 mm travel window is selected over a fixed SAI cylinder when a machine requires frequent product changeovers or precise end-position commissioning without mechanical rework.
As a dimensionally interchangeable ISO 15552 cylinder, it uses the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB/CA/CB/CR mounts. Because the 85 mm stroke is relatively short, side-load risks are minimal, but an external guide is always recommended for heavy lateral loads. This configuration includes a magnet (-S) for CMSE/DMSE switches and a SUS420J2 rod.
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 SAIJ100AX85-75S FAQ
The rear adjuster allows you to trim the effective stroke by up to 75 mm from the 85 mm nominal length, creating a usable travel window of 10 to 85 mm. It acts as a mechanical stop to set the end position and does not function as a lock.
At 0.9 MPa, the push force increases to 7068 N.
