About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-40S
The AirTAC SAIJ100X850-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 40mm trim range, creating an exact 810-850mm usable travel window for precise end-position calibration.
This model includes a piston magnet (-S) for CMSE reed and DMSE electronic sensors, fitting directly into the dual-side extruded barrel grooves. The rear stopper acts purely as a travel end deceleration device, so live air pressure is required to maintain position. It supports a 30-800mm/s speed range and uses a G1/2 port.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX850-40S Is Used
Machine Changeover
Dial in the 810-850mm travel window during product-size changeovers to set new end positions instantly without replacing the cylinder.
End-Position Tuning
Fine-tune the retract stop at commissioning to perfect machine timing, using the 40mm adjustment range to absorb mechanical tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-40S the Right Cylinder?
If your setup requires less thrust, stepping down to an 80mm bore provides 4523N. The adjustable stroke is perfect for commissioning fine-tunes or product-size changeovers without swapping the cylinder or bolting on external stops. Because the 850mm stroke is long, an external guide is recommended to manage side loads on the 25mm rod.
For ISO 15552 replacement matching, specify the 100mm bore, 850mm stroke, 40mm adjustment, PT tapered port threads, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster is not a lock; for load-holding without live air, consider SAIL or BSAI cylinders.
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 SAIJ100AX850-40S FAQ
It can deliver a maximum of 801kgf at 1.0MPa.
The rear adjuster screw lets you trim the effective travel by up to 40mm, creating an 810-850mm usable window. It acts as a mechanical stop to set the end position, but it does not lock the load without live air pressure.
