About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-75S
The AirTAC SAIJ160X145-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 70 to 145 mm, allowing you to dial back the nominal 145 mm stroke by up to 75 mm during commissioning without adding external stops.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It uses PT tapered ports and includes adjustable air cushions at both ends to decelerate heavy moving 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 SAIJ160BX145-75S Is Used
Heavy Press Setup
Fine-tune the 70-145 mm travel window during heavy press commissioning to achieve exact contact depth without swapping cylinders.
Product Changeover
Rapidly adjust the retract end-stop on automated lines when switching between product sizes, minimizing mechanical downtime.
Variable End Stops
Dial in the precise stroke distance for heavy-duty material handling equipment that processes varying package dimensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-75S the Right Cylinder?
Choose the SAIJ adjustable-stroke variant over a fixed SAI model when you need precise end-position tuning during machine setup or product changeover. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an SAIL or BSAI cylinder.
This configuration includes a -S magnet for position sensing, a SUS304 stainless steel rod, and PT threaded ports. It is dimensionally interchangeable per ISO 15552 mounting interfaces. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ160BX145-75S FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back from the 145 mm nominal stroke down to 70 mm. This stop only sets the end position and does not lock or hold the load without live air pressure.
