About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-100
The AirTAC SAIJ80X190-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous 100 mm adjustment range, allowing you to dial the effective travel down from the 190 mm nominal stroke to a 90 mm minimum. This creates a wide 90-190 mm usable window for precise end-position tuning at commissioning. In the 80 mm bore class, it delivers a robust 2268 N pull force at 0.5 MPa and up to 4523 N at 0.9 MPa.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not lock or hold the load without continuous live air pressure. For true load-holding without air, consider an external rod lock or related types like the SAIL or BSAI.

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 SAIJ80BX190-100 Is Used
Product Changeovers
Leverage the 100 mm adjustment range to switch between different package sizes on a conveyor line without disassembling the cylinder or adding external stops.
Machine Setup Tuning
Fine-tune the 90-190 mm travel window during initial commissioning to dial in exact end-of-stroke positions for critical clamping or pressing tasks.
Corrosive Forming
Utilize the SUS304 stainless steel rod in packaging or light forming environments where moisture exposure would degrade standard carbon steel rods.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-100 the Right Cylinder?
You might step down to a 63 mm bore (providing 1402 N pull at 0.5 MPa) if the load is lighter, or step up to 100 mm (3681 N pull at 0.5 MPa) for heavier forces. The 100 mm adjustment range is particularly useful for product-size changeovers on a line, allowing you to reposition the stop without swapping the entire cylinder or adding external spacers.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 190 mm stroke, PT port threads, and the chosen mounting accessory. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting FB, CA, CB, and CR styles. Because this model lacks the -S magnet option, it cannot use AirTAC CMSE or DMSE sensors. Furthermore, the 25 mm rod and M20x1.5 thread handle side loads well, but because the stroke approaches 190 mm, always guide the load externally to prevent rod binding.
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 SAIJ80BX190-100 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw lets you shorten the 190 mm nominal stroke by up to 100 mm, creating a 90-190 mm usable travel window. It functions as a mechanical stop to set the end position and does not hold the load without live air pressure.
