About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-50S
The AirTAC SAIJ80X130-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in fine-tuning allows operators to dial in the retract end-position during commissioning without adding external stops or swapping the entire actuator.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. Fluid is filtered air, operating pressure spans 0.15-1.0 MPa, and the G3/8 PT port ensures high flow for rapid cycling.

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 SAIJ80BX130-50S Is Used
Product Changeovers
Quickly reconfigure the 80-130 mm stroke window on packaging lines when switching to different carton sizes, eliminating the need to physically swap out cylinders.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to prevent crashes, using the rear adjuster to perfectly set the deceleration point without external stopper blocks.
Stainless Rod Operations
Leverage the SUS304 stainless steel rod in washdown or mildly corrosive manufacturing environments where carbon steel rods would degrade over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-50S the Right Cylinder?
The adjustable 80-130 mm travel window is ideal for packaging lines that undergo frequent product-size changeovers, replacing the need to maintain an inventory of multiple fixed-stroke SAI cylinders. For exact ISO 15552 replacement matching, verify the 130 mm stroke, 50 mm adjuster, G3/8 PT port, and SUS304 rod.
Because the nominal stroke is 130 mm, side-loading is less of a concern, but the 25 mm rod and M20x1.5 thread still require external guiding if the load is heavy or off-center. Remember that the rear adjuster acts as a travel stop, not a lock; the SAIJ80X130-50-S will not hold its position without live air. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder, or an external pilot-operated check valve.
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 SAIJ80BX130-50S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 80 to 130 mm, letting you set the exact retract end-position at commissioning. Note that this mechanism is a stop, not a lock, and requires live air to maintain position.
