About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-30S
The AirTAC SAIJ160X140-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 110 to 140 mm. The piston rod is manufactured from SUS304 stainless steel (code B), offering superior corrosion resistance for harsh production environments.
This adjustable-stroke design allows operators to fine-tune the retract end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear screw acts purely as a travel stop to set deceleration limits and does not hold the load without live air pressure.

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 SAIJ160BX140-30S Is Used
Heavy Press Positioning
Dial in the exact 110 to 140 mm retract position for heavy stamping or pressing tools during machine setup without swapping hardware.
Product Size Changeover
Adapt to varying product lengths on a packaging line by turning the rear adjuster to modify the effective end-stop distance on the fly.
Corrosive Assembly Jigs
Leverage the SUS304 stainless steel rod for heavy-duty assembly jigs in washdown or chemically exposed manufacturing areas.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-30S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires heavy thrust—stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, which is often insufficient for high-mass tooling. The 30 mm adjustment window is ideal for variable end-stops during product changeovers. For true load-holding without continuous air pressure, select the SAIL pneumatic lock or BSAI clamp-lock series instead of relying on the SAIJ adjuster.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints but uses a reduced SAIJ accessory set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The fluid port is PT tapered, and the 140 mm stroke is well within the 1500 mm maximum standard travel for this bore.
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 SAIJ160 Adjustable Cylinder SAIJ160BX140-30S FAQ
The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you trim the effective travel back by up to 30 mm, creating a usable 110 to 140 mm stroke window. This stopper only sets the end position and does not lock the load.
