About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-50
The AirTAC SAIJ80X160-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 110 to 160 mm, allowing you to dial back the nominal stroke by up to 50 mm during commissioning. Delivering 2513 N of pull force at 0.5 MPa, it is built with a SUS304 stainless steel piston rod and PT tapered port threads for robust performance.
This adjustable model uses a reduced mounting interface set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear stopper screw acts purely as a travel end-limit and does not hold the load without live air pressure; for fail-safe load holding, consider an external rod lock or the SAIL series. The extruded aluminum barrel includes dual sensor grooves, compatible with AirTAC CMSE reed and DMSE electronic switches when a magnet is specified.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX160-50 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 110 and 160 mm to accommodate different material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the stroke stopper on a packaging line when switching to a new carton size, reducing machine downtime significantly.
Commissioning Calibration
Fine-tune the end-of-stroke position during initial machine setup to prevent crashes, using the rear screw instead of remounting the entire assembly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-50 the Right Cylinder?
Choose this 80 mm bore when 50 mm or 63 mm cylinders lack thrust, as the SAIJ80X160-50 provides 2513 N pull force at 0.5 MPa compared to 1402 N on a 63 mm bore. The 50 mm adjustment window is ideal for production lines running multiple product sizes, letting you fine-tune the retract position without swapping hardware or adding external stops. To match an ISO 15552 replacement, verify the 160 mm stroke, 50 mm adjuster, PT port threads, and SUS304 rod material. Because the stroke is under 300 mm, side-load stress is manageable, but external guides are still recommended for heavy lateral loads.
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 SAIJ80 Adjustable Cylinder SAIJ80BX160-50 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 160 mm down to 110 mm. It functions as a mechanical stop to set the end position, but it does not lock the load without continuous air pressure.
