About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX85-10
The AirTAC SAIJ80X85-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the travel window from 75 to 85 mm without adding external stops.
Because the adjuster acts purely as a mechanical stop on the retract end, it does not hold the load without live air pressure; for true load-holding requirements, consider the SAIL or BSAI series. This 80 mm bore model uses a 25 mm rod and M20x1.5 rod thread to handle high side loads, while the extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.

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 SAIJ80BX85-10 Is Used
Machine Changeover
Dial in the 75-85 mm travel window during product size transitions to set exact retract positions without physically replacing the cylinder.
Assembly Press Fitting
Adjust the 10 mm stroke window on the fly to accommodate slight variations in part tolerances during delicate press-fit operations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX85-10 the Right Cylinder?
The 10 mm adjustment range is perfect for dialing in short 85 mm strokes without swapping out the entire actuator.
For an exact ISO 15552 replacement, match the 80 mm bore, 85 mm stroke, 10 mm adjustment code, PT port thread, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces. Since this is a non-magnetic variant without the -S option, it will not support AirTAC CMSE or DMSE sensors directly.
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 SAIJ80BX85-10 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 85 mm nominal stroke by up to 10 mm, creating a usable travel window of 75 to 85 mm. It only decelerates and sets the end position; it does not lock the load without live air pressure.
