About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-75S
The AirTAC SAIJ80X180-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel from 105 to 180 mm without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This model includes a magnet for position detection, supporting AirTAC CMSE reed switches and DMSE solid-state sensors. The rear adjuster acts solely as a travel stop to set the end position during commissioning; it does not lock the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ80BX180-75S Is Used
Product Changeover
Dial in the 105-180 mm travel window during format changes on packaging lines, avoiding the need to physically swap cylinders for different package sizes.
Machine Setup
Use the rear stopper to precisely set the retract end-position at commissioning, fine-tuning the motion without installing external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-75S the Right Cylinder?
If your force requirements are lower, stepping down to a 63 mm bore provides 2182 N at 0.7 MPa, while stepping up to a 100 mm bore yields 5497 N. The 75 mm adjustment range is ideal for machines processing varying product sizes, allowing operators to dial in the exact stroke rather than swapping out a fixed-stroke SAI cylinder.
When specifying a replacement, ensure you match the ISO 15552 mounting interface dimensions, the PT G3/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the 180 mm stroke is under the 300 mm threshold, side-load concerns are minimal, but always ensure the load is properly guided.
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 SAIJ80BX180-75S FAQ
It can achieve a maximum push force of 513 kgf at 1.0 MPa.
The rear adjusting screw acts as a travel stop, allowing you to trim the nominal 180 mm stroke back by up to 75 mm. This creates a usable travel window of 105-180 mm for fine-tuning end positions without replacing the cylinder.
