About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-50S
The AirTAC SAIJ80X190-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 140-190 mm, letting you dial back the nominal 190 mm stroke by up to 50 mm during commissioning. This bore delivers 2513 N of pull force at 0.5 MPa and reaches 4523 N at 0.9 MPa.
This SKU features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The rear screw acts as a travel stop for end-position tuning, but it does not hold the load without live air. Mounting options include Basic, FA, LB, TC, FTC, TCM1 and TCM2.

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 SAIJ80BX190-50S Is Used
Variable End-Stop Tuning
Dial in the exact 140-190 mm travel distance during machine commissioning without adding external physical stops.
Product Size Changeover
Quickly adapt the cylinder reach on a packaging line when processing different carton or part lengths.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for pushing or pulling tasks in washdown or mildly corrosive settings.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-50S the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N pull at 0.5 MPa) lacks the force for your payload, but you want to avoid the bulk of a 100 mm body. The 50 mm adjustment window is ideal for product changeovers where the exact end-stop varies, unlike a fixed SAI cylinder. For position holding without continuous air pressure, use an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series. To match this ISO 15552 replacement, keep the 80 mm bore, 190 mm stroke, PT ports, and -S magnet.

- ✓ 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 SAIJ80BX190-50S FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw lets you shorten the effective travel from the 190 mm nominal stroke down to 140 mm. It acts as a mechanical stop to fine-tune the end position, but it does not lock the load without live air pressure.
