About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-50S
The AirTAC SAIJ80X180-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 130 to 180 mm without adding external stops. This variant includes a SUS304 stainless steel rod and a magnet for position sensing.
The rear adjustment mechanism acts as a travel stop for end-position tuning during commissioning, but it does not lock or hold the load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series. This model uses a G3/8 PT tapered port and supports mounting options including 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 SAIJ80BX180-50S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 130-180 mm window during machine setup to accommodate different product lengths without swapping cylinders.
Product Changeover Systems
Quickly readjust the stroke stop on packaging or handling lines when switching between product variants, reducing downtime significantly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-50S the Right Cylinder?
The 50 mm adjustable range is ideal for product changeovers on a line where end positions frequently vary by part size. When replacing an ISO 15552 cylinder, match the 80 mm bore, 180 mm stroke, 50 mm adjustment, G3/8 PT ports, and the -S magnet requirement. The 25 mm rod and M20x1.5 thread handle substantial side loads, but for this 180 mm stroke, ensure external guiding if heavy lateral forces are present.
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 SAIJ80BX180-50S FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke anywhere within a 130 to 180 mm travel window. It requires live air to maintain position and does not function as a lock.
