About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-10
It features a robust 25mm piston rod and a PT G3/8 port. By integrating a rear stopper screw, this model allows you to fine-tune the effective stroke during commissioning, providing a usable travel window of 165-175mm without adding external stops.
This extruded aluminum barrel omits heavy tie-rods and includes sensor grooves on both sides for straightforward position feedback. Configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance, it operates at speeds of 30-800mm/s. The rear adjuster acts purely as a travel stop to set deceleration and end positions, meaning it will not hold a load without continuous live air pressure.

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 SAIJ80BX175-10 Is Used
Machine Setup Calibration
Dial in the exact 165-175mm end position during initial commissioning to perfect a pressing operation without machining custom spacers.
Product Changeover
Quickly adjust the rear stopper by up to 10mm on a packaging line when switching to a slightly different product size.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-10 the Right Cylinder?
The 10mm adjustment range is ideal for dialing in exact end positions during machine setup or product changeovers, offering flexibility that a fixed-stroke SAI cannot match. To replace an ISO 15552 cylinder, match the 80mm bore, 175mm stroke, PT G3/8 port, and your required mounting style.
Because the nominal stroke is under 300mm, side-load stress on the 25mm rod is manageable for standard loads, though long unsupported strokes still require external guiding. For applications needing true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder, as the SAIJ adjuster is not a locking mechanism. This specific SKU lacks a magnet, so it requires external physical sensors rather than CMSE or DMSE switches.
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 SAIJ80BX175-10 FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 175mm nominal stroke by up to 10mm. This creates a 165-175mm usable travel window for fine-tuning end positions without replacing the cylinder.
