About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-100S
The AirTAC SAIJ160X145-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 45 mm from the 145 mm nominal stroke. This wide 100 mm adjustment range is ideal for accommodating multiple product sizes on a single line without physically swapping the actuator.
This unit is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries the -S magnet option for compatibility with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the fluid porting uses PT tapered threads (G3/4). The rear adjuster acts purely as a mechanical stop to set the end position and relies on the integrated air cushions for deceleration; it does not lock or 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 SAIJ160BX145-100S Is Used
Variable Product Changeover
Dial in the 45-145 mm travel window during format changes on packaging lines, allowing a single cylinder to process multiple carton sizes without mechanical rebuilds.
Commissioning End-Tuning
Fine-tune the exact retract end-position during machine setup to perfect pressing forces, avoiding the need to add external shims or swap out the entire actuator.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-100S the Right Cylinder?
Choose this adjustable SAIJ over a fixed-stroke SAI when your machine setup involves frequent product changeovers that demand variable end-stops.
For an exact ISO 15552 dimensional replacement, match the 160 mm bore, 145 mm stroke, 100 mm adjustment range, PT G3/4 ports, SUS304 rod, and -S magnet. The available mounting interface is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 145 mm, you are under the 300 mm threshold where external side-load guides become strictly critical, but the robust 40 mm rod and M36x2 thread still handle high offset loads effectively. Remember that the rear adjuster is a stop, not a brake; for true load-holding without live air, use an SAIL or BSAI cylinder.
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 SAIJ160BX145-100S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window between 45 and 145 mm, which is set at commissioning without needing to replace the cylinder.
If you increase the pressure to 0.7 MPa, the push force rises to 14074 N.
