About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-40S
The AirTAC SAIJ80X200-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 160-200 mm usable travel window from its 200 mm nominal stroke. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for CMSE reed and DMSE electronic solid-state switches.
This configuration uses a SUS304 stainless steel rod for corrosion resistance and PT tapered ports. The 25 mm rod and M20x1.5 thread handle side loads well, but long unsupported strokes still need an external guide. The rear adjuster acts purely as a travel stop for end-position tuning at commissioning; it does not hold the load without live air.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX200-40S Is Used
Machine Changeover
Dial in the exact retract position within the 160-200 mm window during product size transitions without adding external stops.
Variable End-Stop
Set precise end-of-stroke limits for multi-format assembly lines using the 40 mm rear adjustment screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-40S the Right Cylinder?
An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune the retract end-position during machine setup or product changeover without swapping hardware. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
For ISO 15552 replacement matching, specify bore 80, stroke 200, adjustment 40, PT ports, SUS304 (B) rod material, and the -S magnet. Because the nominal stroke is 200 mm, an external guide is recommended for heavy side loads. If you need true load holding without live air, the rear stop is not a lock; consider an SAIL or BSAI cylinder instead.
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 SAIJ80 Adjustable Cylinder SAIJ80BX200-40S FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw trims the effective travel back by up to 40 mm, creating a 160-200 mm usable stroke window. It functions as a hard stop for position tuning, not a load-holding lock.
