About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-40
The AirTAC SAIJ160X140-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 140 mm stroke that can be fine-tuned backward, delivering a usable travel window of 100-140 mm to perfectly dial in end positions during commissioning.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and ships without a magnet. It uses a PT tapered port thread and relies on a variable air cushion at both ends to decelerate heavy loads. The rear adjuster acts strictly as a travel stop for position tuning, meaning it will not hold a load safely without continuous 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 SAIJ160BX140-40 Is Used
Heavy Press Tuning
Dial in the exact 100-140 mm pressing depth during machine commissioning without swapping out the entire cylinder or fabricating spacer shims.
Product Changeover
Quickly adjust the rear stopper to accommodate different product heights on a production line, minimizing downtime between batch runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-40 the Right Cylinder?
Choose this adjustable-stroke SAIJ variant over a fixed-stroke SAI when you need to trim the travel window between 100 and 140 mm without adding external physical stops.
For an exact ISO 15552 replacement, match the 160 mm bore, 140 mm stroke, 40 mm adjustment range, PT port thread, and SUS304 rod material. Note that this unit lacks a magnet; adding an -S suffix is required if you need to track position with CMSE reed or DMSE electronic sensors. Because the nominal stroke is 140 mm, side-load risks are moderate, but always ensure adequate external guiding for the heavy 160 mm class piston rod. If your process requires true load-holding without live air, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ160BX140-40 FAQ
The rear adjuster screw allows you to shorten the effective travel from the nominal 140 mm down to 100 mm. This creates a 100-140 mm usable window for fine-tuning the end position at commissioning, but the adjuster functions only as a mechanical stop and does not lock the load without live air.
