Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-10
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX230-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-10
It features a SUS304 stainless steel rod and PT tapered ports. By turning the rear screw, you can trim the effective travel within a 220-230mm window, providing precise end-position tuning during commissioning without needing external stops.
This adjustable-stroke design allows for rapid machine changeovers and product-size adjustments on the fly. The rear mechanism acts purely as a travel stop to set the retraction endpoint and relies on the integrated air cushion for deceleration; it is not a locking device. For applications requiring true load-holding without live air pressure, an external pilot-operated check valve or a dedicated SAIL locking cylinder is required.

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 SAIJ80BX230-10 Is Used
Product Size Changeovers
Dial in the 220-230mm retraction window quickly when switching between product sizes on a packaging line, avoiding the need to physically swap cylinders or add spacer blocks.
Machine Setup Commissioning
Fine-tune the end-stop during initial machine commissioning to achieve exact positioning, using the rear adjuster to perfect the 230mm nominal stroke.
Variable End-Stop Positioning
Ideal for automated assembly stations where the retraction point needs occasional micro-adjustments to accommodate varying material thicknesses without reprogramming the motion controller.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-10 the Right Cylinder?
Selecting this 80mm bore makes sense when your application requires substantial thrust but demands on-the-fly end-position tweaking; if you need less force, the 63mm bore provides 1559N at 0.5 MPa. Choose the SAIJ adjustable format over a fixed-stroke SAI cylinder when you anticipate minor product variations or need to dial in a precise retraction point. To match this exact ISO 15552 replacement, specify: 80mm bore, 230mm stroke, 10mm adjustment, PT ports, SUS304 (B) rod material, and no magnet. Because the 230mm stroke is relatively long, ensure external guides are used to prevent excessive side-loading on the rod.
Mounting options for this series include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations. The extruded aluminum barrel includes sensor grooves on both sides, though this specific unit lacks the -S magnet and therefore cannot host CMSE or DMSE switches without a configuration change.
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 SAIJ80BX230-10 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the 230mm nominal stroke by up to 10mm, creating a usable travel window of 220-230mm. This stopper sets the end position but does not lock the load without continuous air pressure.
