About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-50S
The AirTAC SAIJ160X140-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 14074N at 0.7 MPa, making it ideal for heavy-duty operations. The integrated -50 mm adjustment screw allows you to fine-tune the effective travel down from the 140 mm nominal stroke, creating a precise 90-140 mm usable window without swapping out hardware.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads ensure a robust pneumatic connection.

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 SAIJ160BX140-50S Is Used
Heavy-Duty Pressing
Dial in the exact 90-140 mm pressing depth during setup to accommodate different material thicknesses without changing the cylinder.
Robotic End Effectors
Utilize the SUS304 stainless steel rod for corrosion resistance in washdown environments while fine-tuning the tooling reach.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-50S the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI model when you need to dial in the exact end-of-stroke position during commissioning or product changeover. Because the stroke is 140 mm, side-loading is manageable, but always ensure adequate external guiding for heavy loads.
For an exact ISO 15552 replacement match, verify the 160 mm bore, 140 mm stroke, 50 mm adjustment range, PT G3/4 port, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX140-50S FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 50 mm. This creates a usable stroke window of 90 to 140 mm, letting you set the exact retract end-position during commissioning without adding external stops.
At 0.5 MPa it pushes 10053N and pulls 9425N. At 0.9 MPa, the push force increases to 18095N, with a maximum rated force of 2050 kgf at 1.0 MPa.
