About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-40S
The AirTAC SAIJ80X175-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 135 to 175 mm, allowing you to dial back the nominal 175 mm stroke by up to 40 mm during commissioning without adding external stops.
This variant features a SUS304 stainless steel piston rod (code B) for superior corrosion resistance and ships with a magnet for position sensing. It accepts CMSE reed and DMSE electronic solid-state switches in its dual-side sensor grooves. The PT tapered port threads ensure a tight pneumatic seal, while the integrated air cushions handle end-of-stroke deceleration.

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 SAIJ80BX175-40S Is Used
Machine Changeover
Dial in the exact 135 to 175 mm end position during product size changeovers without swapping the physical cylinder or adding shims.
Variable End Stops
Use the 40 mm adjustment window to set precise retract positions for multi-format assembly tooling, monitored via DMSE electronic sensors.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-40S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (982 N at 0.5 MPa) lacks the thrust for your tooling but a 100 mm bore (3927 N) would be excessive overkill. The 40 mm adjustment range is ideal for product changeovers where the exact end-of-stroke position must be fine-tuned on the machine, replacing the need to swap out a fixed-stroke SAI cylinder.
Because the rear adjuster acts purely as a mechanical travel stop and the air cushions only manage deceleration, neither will hold a load without live air pressure. For fail-safe load holding, consider an external rod lock or the AirTAC SAIL or BSAI series. For this 175 mm stroke, side loads are moderate, but always guide the load externally to prevent rod binding.
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 SAIJ80BX175-40S FAQ
The rear adjuster screw lets you mechanically shorten the 175 mm nominal stroke by up to 40 mm, creating a usable travel window of 135 to 175 mm. It functions as an end-position stop and does not lock the load without live air.
