About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-75
The AirTAC SAIJ80X200-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a highly flexible usable travel window of 125 to 200 mm, letting you dial in the exact retract end position during commissioning without swapping out the cylinder or adding external stops.
This specific configuration utilizes a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads for a reliable pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept AirTAC CMSE reed or DMSE electronic sensors if a magnet is added later. It is important to note that the rear adjuster functions strictly as a travel stop and does not lock 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 SAIJ80BX200-75 Is Used
Machine Changeover
Quickly adapt retract distances from 125 to 200 mm when switching between different product sizes on a packaging line, minimizing downtime.
End-Position Tuning
Fine-tune the exact stopping point during machine commissioning without machining external stop blocks or changing the cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-75 the Right Cylinder?
The wide 75 mm adjustment range is perfect for product-size changeovers on a packaging line, replacing the need to inventory multiple fixed-stroke SAI cylinders. To match this model exactly when replacing an ISO 15552 unit, specify the 80 mm bore, 200 mm stroke, 75 mm adjustment, PT port thread, SUS304 rod, and your required mounting bracket from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the nominal stroke is 200 mm, side-loading is manageable, but always ensure adequate external guiding if the load is heavy or offset. Remember that for load-holding without continuous air pressure, you must look to a SAIL locking cylinder or an external rod lock, as the SAIJ adjuster only acts as a physical stop.
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 SAIJ80BX200-75 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 200 mm nominal stroke by up to 75 mm. This provides a usable travel window of 125 to 200 mm, which can be fine-tuned during setup without replacing the cylinder.
