About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX100-40
The AirTAC SAIJ160X100-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 40 mm. This yields a usable stroke window of 60 to 100 mm, enabling precise end-position tuning at commissioning without adding external stops or swapping the barrel. Built with a robust 40 mm SUS304 stainless steel rod and a PT G3/4 port, it delivers substantial thrust, generating 9425 N of pull force at 0.5 MPa.
Because the rear adjuster acts purely as a mechanical stop, it does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. This model omits the FB, CA, CB, and CR mounting interfaces, supporting a focused set of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides, ready for direct CMSE reed or DMSE solid-state switch integration when a magnet is specified.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|

| 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 SAIJ160BX100-40 Is Used
Variable End-Stop Positioning
Dial in the exact 60-100 mm travel window during machine commissioning to fine-tune end positions without physically swapping out the cylinder.
Product Size Changeover
Adapt quickly to varying product dimensions on a packaging line by adjusting the rear stopper up to 40 mm, accommodating different package sizes on the fly.
High-Force Clamping
Leverage the 9425 N pull force at 0.5 MPa for heavy-duty clamping tasks, using the adjustable stroke to prevent over-travel and precisely control clamping depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX100-40 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high force combined with variable end-stop positioning, such as accommodating product size changes on a line. If the 9425 N pull force at 0.5 MPa is excessive, stepping down to a 125 mm bore yields 5734 N, whereas moving up to a 200 mm bore provides 15080 N. The SUS304 rod material is specifically chosen here for corrosion resistance in harsher environments. Unlike a fixed-stroke SAI cylinder, this SAIJ variant allows you to dial in the exact 60-100 mm travel window during setup.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 100 mm nominal stroke, 40 mm adjustment range, PT G3/4 port, and the required mounting interface. For any stroke of 300 mm or more, external guiding is recommended to manage side loads, though this 100 mm stroke typically avoids such issues. To hold a load without live air, an external rod lock or pilot-operated check valve is required.
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 SAIJ160BX100-40 FAQ
The rear adjuster acts as an external mechanical stop that lets you shorten the nominal 100 mm stroke by up to 40 mm. This creates a usable travel window of 60 to 100 mm, allowing precise end-position tuning without changing the cylinder.
