About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-100S
The AirTAC SAIJ80X175-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE solid-state switches seated in the dual-side sensor grooves.
With a 175 mm nominal stroke and a 100 mm adjustment range, this SKU provides a wide usable travel window of 75 to 175 mm. This allows operators to dial in exact retract end positions during commissioning without adding external stops. The rear screw acts purely as a travel stop for deceleration alongside the standard air cushions; it is not a lock, so load holding requires live air or a separate SAIL/BSAI locking cylinder.

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 SAIJ80BX175-100S Is Used
Variable End-Stop Tuning
Ideal for packaging lines where the retract position must be shifted by up to 100 mm to accommodate different carton depths without changing the cylinder.
Product Size Changeover
Enables rapid format adjustments on automated assembly equipment by simply rotating the rear adjuster rather than replacing the entire actuator.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-100S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust, stepping up from a 63 mm bore that yields 1559 N at 0.5 MPa. The 100 mm adjustment range is ideal for machinery that frequently processes varying product sizes, allowing the retract endpoint to be reconfigured rapidly rather than swapping out a fixed-stroke SAI cylinder. To replace an ISO 15552 unit, match the 80 mm bore, 175 mm stroke, PT ports, SUS304 rod, and the -S magnet.
Because the 175 mm stroke is relatively long, the 25 mm rod and M20x1.5 thread provide robust support, but an external guide should still be used to prevent excessive side-loading on the extruded aluminum barrel. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ80BX175-100S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster allows you to shorten the 175 mm nominal stroke by up to 100 mm, creating a usable travel window of 75 to 175 mm. This stopper only sets the end position and does not lock the load without live air pressure.
