About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-40S
The AirTAC SAIJ80X160-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This built-in adjuster allows you to fine-tune the retract end position during commissioning without adding external stops.
Built for demanding environments, this variant uses a SUS304 stainless steel rod and PT tapered ports. It includes a magnet for CMSE and DMSE sensors, with extruded aluminum barrel sensor grooves on both sides. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ80BX160-40S Is Used
Variable End-Stop Machining
Dial in the exact 120-160mm retract position during product changeovers without disassembling the fixture or swapping cylinders.
Commissioning Fine-Tuning
Use the 40mm rear adjustment screw to perfectly align the tooling contact point at machine setup, absorbing mechanical tolerances.
Adjustable Diverter Arm
Accommodate different package sizes on a sorting line by adjusting the stroke window rather than repositioning the entire actuator assembly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-40S the Right Cylinder?
Choose this 80mm bore when 50mm (982N at 0.5MPa) is too weak but 100mm (3927N at 0.5MPa) is oversized. The 40mm adjustment range is ideal for machines processing variable product sizes, letting you dial in the exact end stop on the fly instead of swapping cylinders. For any stroke of 300mm or more, an external guide is recommended to handle side loads, though this 160mm stroke is well within standard limits.
As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. To match this exact configuration, specify: 80mm bore, 160mm stroke, 40mm adjustment, PT ports, SUS304 (B) rod material, and a -S magnet. Note that the rear adjuster is a travel stop, not a lock; it will not hold the load without live air pressure. For true load-holding, consider the SAIL or BSAI series.
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 SAIJ80BX160-40S FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop that can shorten the 160mm nominal stroke by up to 40mm, creating a usable travel window of 120 to 160mm. It requires live air pressure to maintain position, as the adjuster is a stop, not a locking device.
