About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-30S
The AirTAC SAIJ160X185-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 185 mm nominal travel by up to 30 mm for a precise 155-185 mm usable window. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet enables seamless position detection.
This model utilizes PT tapered ports and operates within a 30-500 mm/s speed range. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load without continuous live air. For position holding without pneumatic pressure, an external rod lock or a related SAIL pneumatic-lock cylinder is required.

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 SAIJ160BX185-30S Is Used
Heavy Press Tuning
Dial in the exact 155-185 mm retract end-stop during machine commissioning to accommodate varying material thicknesses without adding external mechanical stops.
Corrosive Assembly
Utilize the SUS304 stainless steel rod in humid or washdown assembly stations, relying on the DMSE electronic sensors for precise end-position confirmation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-30S the Right Cylinder?
Selecting this 160 mm bore cylinder is ideal when your application requires the substantial thrust of a larger rod diameter to handle heavy side loads, though for strokes of 300 mm or more you should still incorporate an external guide. This adjustable-stroke model is chosen over a fixed SAI cylinder when you need variable end-stops or rapid product changeovers without swapping hardware.
When specifying an ISO 15552 replacement, match the 160 mm bore, 185 mm stroke, 30 mm adjustment range, PT port threads, and the -S magnet requirement. The SAIJ series supports a specific mounting subset—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR styles. The -S magnet works precisely with AirTAC CMSE reed switches and DMSE electronic solid-state sensors.

- ✓ 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 SAIJ160BX185-30S FAQ
At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster acts as a mechanical stop that shortens the 185 mm nominal stroke by up to 30 mm, creating a 155-185 mm travel window. It only sets the end position and does not hold the load without live air pressure.
