About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-30S
The AirTAC SAIJ80X160-30-S 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 30 mm. This creates a 130-160 mm usable stroke window, letting you dial in the exact retract position without adding external stops.
Equipped with a SUS304 stainless steel rod (code B) and a PT tapered port, this unit handles demanding environments. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. The rear adjuster acts only as a travel stop, so you must maintain live air pressure to hold a load, unlike the SAIL or BSAI locking cylinders.

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 SAIJ80BX160-30S Is Used
Machine Changeover
Fine-tune the 130-160 mm retract position during product size changes without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Dial in the exact end-of-stroke location at commissioning using the rear adjuster to compensate for mechanical tolerance stack-ups.
Variable End Stops
Set custom retraction depths on automated assembly lines where multiple products require slightly different cylinder travel distances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-30S the Right Cylinder?
Choose this 80 mm bore when you need more thrust than the 63 mm variant (1559 N at 0.5 MPa) but want to avoid the bulk of a 100 mm body. The adjustable stroke is perfect for machine changeovers, letting you fine-tune the end position on the fly instead of swapping out a fixed-stroke SAI cylinder. For a direct ISO 15552 replacement, match the 80 mm bore, 160 mm stroke, 30 mm adjustment, PT G3/8 port, and -S magnet.
Since the 160 mm stroke is under the 300 mm side-load threshold, you can mount it using the standard SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) without needing external guides. The 25 mm rod and M20x1.5 thread provide robust resistance to bending, though the air cushions at both ends handle deceleration rather than locking the load.
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 SAIJ80BX160-30S FAQ
It can reach up to 4523 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 160 mm nominal stroke by up to 30 mm, providing a 130-160 mm travel window. It acts as a mechanical stop and does not lock the load without live air pressure.
