About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-40
The AirTAC SAIJ80X175-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 175 mm stroke that can be fine-tuned down by up to 40 mm, creating a precise 135-175 mm usable travel window for product changeovers. The extruded aluminum barrel includes sensor grooves on both sides.
This specific configuration utilizes a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The 25 mm rod and M20x1.5 thread provide robust side-load capacity, though external guides are still recommended for optimal performance. The rear adjuster acts strictly as a mechanical stop to set the end position and does not hold the load without 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 SAIJ80BX175-40 Is Used
Machine Changeover
Quickly dial in the 135-175 mm travel window when switching product sizes on a packaging line, avoiding physical cylinder swaps.
End-Position Tuning
Fine-tune the retract stop during commissioning to perfect material seating without machining custom external spacers.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-40 the Right Cylinder?
The 40 mm adjustment range is ideal for dialing in exact end positions during commissioning without adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock. Dimensionally interchangeable per ISO 15552, replacement requires matching the 175 mm stroke, 40 mm adjuster, PT ports, SUS304 rod, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. Since the stroke is under 300 mm, side-load risks are moderate, but proper guiding remains best practice.

- ✓ 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 SAIJ80BX175-40 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from 175 mm down to 135 mm. It sets the travel end point but does not lock the load without live air pressure.
