About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-30S
The AirTAC SAIJ160X155-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 125 to 155 mm for precise end-position tuning. Delivering massive thrust, it pushes 18095 N and pulls 9425 N at 0.9 MPa. The extruded aluminum barrel features sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback.
This model utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance, paired with a G3/4 PT tapered port and an M36x2 rod thread. The rear stopper allows you to dial in the exact retract distance during commissioning without adding external stops. It includes adjustable air cushions at both ends with a 50 mm cushion stroke to decelerate heavy loads smoothly.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX155-30S Is Used
Heavy Press Tuning
Fine-tune the 125 to 155 mm travel window during machine setup to apply exact clamping force without mechanical modifications.
Product Size Changeover
Quickly adjust the retract end-stop by up to 30 mm when switching between different product dimensions on a heavy assembly line.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for high-thrust pushing tasks in washdown or chemically exposed manufacturing settings.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-30S the Right Cylinder?
The adjustable stroke is ideal for product changeovers on heavy machinery, letting you trim the travel back by up to 30 mm instead of swapping cylinders. For load-holding without live air pressure, note that the rear adjuster is a travel stop, not a lock; you would need an external rod lock, a pilot-operated check valve, or the SAIL/BSAI cylinder variants. When replacing an ISO 15552 unit, match the 155 mm stroke, 30 mm adjustment, G3/4 PT port, and the -S magnet requirement.
Because the 155 mm stroke is relatively short for this large bore, side-load stress is minimal, but you should still ensure the M36x2 rod thread is properly aligned to avoid binding. The robust SUS304 rod material handles demanding environments better than standard carbon steel.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX155-30S FAQ
At 0.5 MPa, the push force is 10053 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 155 mm down to 125 mm. It sets the travel end and relies on the air cushion for deceleration, but it does not lock the load without live air pressure.
